5th Grade - Gateway 2

The materials reviewed for STEMscopes Math Grade 5 meet expectations for developing conceptual understanding of key mathematical concepts, especially where called for in specific content standards or cluster headings.

STEMscopes materials develop conceptual understanding throughout the grade level. In the Teacher Toolbox, STEMscopes Math Philosophy, Elementary, Conceptual Understanding and Number Sense, STEMscopes Math Elements, this is demonstrated.  “In order to reason mathematically, students must understand why different representations and processes work.” Examples include:

• Scope 6: Model the Four Operations with Decimals, Explore 1–Adding Decimals, Procedure and Facilitation Points, students develop conceptual understanding of adding whole numbers and decimals to the hundredths place. “1. Read the following scenario: a. Mr. Hunley makes wooden signs for friends and family. He has decided that he wants to build other things too! Help Mr. Huntley figure out the total amount of wood needed for his different projects. 2. Pass out a set of bases ten blocks, Scenario Cards, and 2 complete Place Value Mats to each group. Distribute a Student Journal to each student. 3. Students should begin by reading the first Scenario Card and discussing with their group members what is happening in the problem. 4. Explain to students that we are going to change our whole. Instead of the unit cube as a value of 1, we are going to use the 100 flat as the value of 1. 5. Have the students work together to discuss and solve the following questions. Allow time for students to discuss and then share. a. DOK-1 If the 100 flat has a value of 1, what is the value of the rod? b. DOK-1 If the rod has a value of 0.1 or \frac{1}{10}, what is the value of the unit? 6. Next ask students to discuss and then share how they use place value when adding whole numbers. Listen and guide students as they talk within their groups before sharing. Students must have the following understanding: a. Digits 0-9 have a different value depending on the position in a number. b. Add whole numbers with like units, such as the digits in the ones place are added, the digits in the tens place are added, the digits in the hundreds place are added, etc. c. Regrouping or renaming numbers to add.$$79+8$$ -add 9 ones and 8 ones and regroup to have 1 ten and 7 ones to make 87. Students may rename 7 tens to make 79 ones to add 8 ones. Emphasize the same units that must be added. 7. Explain to students that adding decimals is the same as when they add with whole numbers. a. Digits have different values depending on the position in a number. b. Decimals use the base ten format the same as our whole numbers. c. Add the same units such as ones added with ones, tenths added with tenths, and hundredths added with hundredths. d. Flexible thinking by decomposing your digits and then composing your numbers to combine the values. 8. Students should use the base ten blocks to model the numbers being added on their Place Value Mats. Each number should be modeled on its own Place Value Mat before they are added together. 9. Ask students before they begin adding the decimals to refer back to the scenario. a. DOK-2 About how many feet do you think Mr. Henley will need for his project? Students should estimate the sum for 2.8 and 1.48. Listen to students’ understanding of place value and estimation. 10. Students will then combine the amounts and record the totals. If needed, students should regroup 10 of a place value for one of the next-highest place values or rename to add the values. 11. As students are working, circulate around the room and discuss the following: a. DOK-2 What did you have to do if there were 10 or more in one place value? b. DOK-2 Why do you think the Place Value Mat has the place values lined up? 12. Ask students if their estimations were close to their solutions. Discuss why or why not. 13. Representing the number that was built with base ten blocks, students should shade in grids and record as equations on their Student Journals. Students should repeat this process for each Scenario Card. 14. After the Explore, invite the class to a Math Chat to share their observations and learning. 15. When students are done, have them complete the Exit Ticket to formatively assess their understanding of the concept.” (5.NBT.7)

• Scope 9: Add and Subtract Fractions, Engage, Foundation Builder, Solve and Justify, Part 2, develops students’ conceptual understanding as they reason about different representations for fractions. “Continue to project the slideshow for student reference. Place students in small groups. Provide each group with a student handout and preview the instructions. Provide students access to fraction towers and explain that this visual tool can be used while solving a problem. Provide each group access to materials for making a visual display. Discuss the components of a visual display: It should be written in large bold writing. All work should be shown in an organized fashion. Colors may be used to emphasize key steps, but they should not be distracting or used for decorative purposes. Any combination of visual models, words, numbers, and equations are included to communicate thinking. Discuss how to prepare an explanation for the visual display: Determine who will speak and in what order, and practice the explanation several times. Have students work together to solve each problem. Find as many different strategies as possible, approve student work, and have each group make one visual display. Try to include an example of each type of each visual fraction model used in the class. Have each group post their visual display for the whole class to see. Allow groups to visit one another’s displays as they think about how each solution is similar or different from one another. Bring the whole class together. Invite students to share their visual displays and to explain their thinking. Highlight any additional visual fraction models that were not previously demonstrated on the slideshow. Discussion points: When you add or subtract fractions, what is the denominator of the solution? Explain why. The denominator is the same as that of the fractions you were adding together or subtracting. The denominator shows the size of the pieces, so it doesn’t change if you add on or take away some of the pieces. How do you find the numerator of the sum or difference? You add or subtract the numerators of the fractions. How does a number line help you add or subtract fractions? You can see how many tick marks to add or subtract to see what the total is. Each fraction you are adding or subtracting can be a jump on a number line. Once you put all the jumps together, you will land on the final solution. You jump to the right to model addition and jump to the left to model subtraction. How do fraction towers or tape diagrams help you add or subtract fractions? You can see how many fractional parts make up a whole. Each fraction part is the same size within the model. You can shade in or build on parts that are added on or remove parts that are taken away.” (5.NF.1)

• Scope 17: Volume in Cubic Units, Explore 1–Cubic Units, Procedure and Facilitation Points, students develop conceptual understanding of a cube with a side length of one as a unit cube and understand that the volume of a three-dimensional figure is the number of unit cubes packed within the space without gaps or overlaps. “Part 1: Boxing Hats, 1. Read the following scenario: a. The Jolly Elf hat Factory just got a big order for elf hats at the North Pole, and they have hired you to pack shipping boxes with the elf hats! It is your job to fit as many elf hats into each shipping box as you can. Each centimeter cube contains one elf hat. The boxes will have lids, so the elf-hat boxes cannot go over the top of the shipping box. 2. Give each student a Student Journal. Give each group Shipping Box 1, a centimeter ruler, and a centimeter cubes. Ask questions such as the following: a. DOK-1 How can you pack the boxes so that you can fit as many elf hats into Shipping Box 1 as possible? 3. Explain that students should record how many elf hats fit the length, width, and height of Shipping Box 1 on their Student Journals. 4. Allow students to pack the boxes and write their cube totals.  5. After they have packed their boxes with cubes, students should measure the length, width, and height of the shipping box and the elf-hat boxes using the centimeter ruler. Students should record these measurements on their Student Journals. Ask questions such as the following: a. DOK-1 What are the dimensions of the elf-hat boxes that you measured? 6. Explain that this is called a cubic centimeter. Have students refer to the cubic foot and cubic yard or meter that was built. . Discuss with students how each of these are called cubic units because their length, width, and height are each 1 unit of measure. For this activity, students will be working with cubic centimeters. For the “Missing boxes” part of this lesson, students will be using cubic centimeters and cubic inches. a. DOK-1 How many elf hats could you fit into a shipping box with dimensions of 5 cm long, 4 cm wide, and 3 cm tall?  7. Explain that the word for the amount of space objects or substances take up is volume. 8. Explain that because the cubes fit together side by side, we use cubic units to measure the space, or volume, inside an object like the shipping box. Ask questions such as the following: a. DOK-2 What is the volume of Shipping Box 1? 9. Students should write the volume of Shipping Box 1 on their Student Journals. 10. Give students Shipping Box 2. Ask questions such as the following: a. DOK-2  Compare Box 1 and Box 2. Which box do you think will hold more elf hats? b. DOK-1 How will you find the volume of this box? 11. Have students complete the information for Shipping Box 2 on their Student Journals. As students are working, monitor and check for understanding. Ask questions such as the following: a. DOK-1 How many eld-hat boxes could you fit into Shipping Box 2? b. DOK-1 What is the volume of Shipping Box 2? Part ll:nMissing Boxes 1. Tell students the Jolly Elf Hat Factory didn’t get their shipment of new boxes in yet, but they still need to figure out how many elf-hat boxes will fit into each shipping box when they do arrive. The factory knows many eld-hat boxes will fit in the length, the width, and the height of each box. a. Questions 3 and 4 are in cubic centimeters and 5 and 6 are in cubic inches. Be sure to emphasize that students need to be mindful when answering questions, using manipulatives, and labeling correctly. 2. Tell students that even though they don’t have the shipping boxes, they can still use the centimeter cubes to build the box shape and determine the volume of the shipping box. 3. Have students work on building the boxes using the information on the Student Journal and centimeter and inch cubes. Students should complete the information on their Student Journals. 4. As students are working, monitor and check for understanding. Ask questions such as the following: a. DOK-2 How did you know many centimeters the length of Shipping Box 3 was? b. DOK-1 What are the dimensions of the bottom, or base, of Shipping Box 4? 5. After students have found the volume of Shipping Boxes 3 - 6, have them meet with another group and review their answers. If there are discrepancies with the answers, have them rebuild the boxes using the centimeter or inch cubes and reach an agreement on the volume of the boxes. 6. Students should complete the reflection question on their Student Journals. 7. After the Explore, invite the class to a Math Chat to share their observations and learning.  8. When students are done, have them complete the Exit Ticket to formatively assess their understanding of the concept. 9. Return to the Hook, and instruct students to use their newly acquired skills to successfully complete the activity.” (5.MD.3) 

The materials provide opportunities for students to independently demonstrate conceptual understanding throughout the grade level. Examples include:

• Scope 7: Multiply Multi-Digit Whole Numbers, Elaborate, Fluency Builder-Multiplication Baseball, Procedure and Facilitation Points, students use the algorithm to multiply multi-digit whole numbers. The game cards used provide three by two multiplication problems for students to solve. “1. Demonstrate how to play a few rounds with another student. Students will need to become familiar with the basic skills of baseball. 2. Stack the game cards facedown in the center of the game board. 3. Roll a die to see who is at bat first. The player who rolls the greater number is the batter. The other player is the pitcher. 4. The batter should line up his or her four counters behind home plate. 5. The pitcher will draw a card from the pile without showing the batter and read it aloud. 6. The batter will solve the problem on scratch paper. The pitcher will check the batter’s work. The correct answer to each problem is in blue at the bottom of each card. 7. If the batter answers correctly, he or she will roll the die to see where to move his or her first counter. a. Roll a 1 or 3: Move to first base. b. Roll a 2 or 4: Move to second base. c. Roll a 5: Move to third base. d. Roll a 6: Home run! 8. If the batter answers incorrectly, it is an out. The pitcher should use the dry-erase marker to put a tally mark in the Outs section of the game board, 9. The pitcher places the game card in a separate pile. Game cards will only be used once each game. 10. The pitcher draws and reads a new equation card to the batter. The batter again answers and follows the rules in steps 7 and 8 of these instructions. Note: You should show students how to move multiple counters that are in play. For example, if the batter’s first counter is on second base and the batter rolls a 5 on his or her next turn, the batter will move the first counter home, and the second counter will go to third base. Model how to keep track of runs. 11. The batter will keep track of his or her runs by using the dry-erase marker to put tally marks in the Runs section of the game board. 12. Repeat steps 4-10 of these instructions until the batter has either gotten three outs or moved all his or her counters home. When either of these things happens, players will switch roles and begin a new inning. 13. Play four innings and count up the runs to determine the winner. 14. Students will work to complete the student recording sheet. They will be creating multiplication equations on their own and trade papers with their partner. Their partner will have to solve in the Work Space column on the recording sheet. a. Remind students to use a three-digit number multiplied by a two-digit number for their multiplication equation.” (5.NBT.5)

• Scope 9: Add and Subtract Fractions, Explain, Show What You Know-Part 1: Addition with Unlike Denominators Using Equivalent Fractions, students use pictorial models to find common denominators to add fractions. Students should individually complete the Show What You Know activity that correlates with the Explore activity they just completed. Each Show What You Know piece correlates with the same number Explore. For example, Show What You Know Part 1 will allow students to practice the skills they developed in Explore 1. “Find the common denominator and use equivalent fractions to solve. Complete the missing values within each row. \frac{3}{4}+\frac{1}{5} Visual Model ___ Equations ___   \frac{1}{2}+\frac{1}{3} Visual Model ___ Equations ___” (5.NF.1)

• Scope 10: Model Fraction Multiplication, Evaluate, Skills Quiz, engages students in conceptual understanding as they connect fraction equations with models. “Match the fraction equation to the fraction model it represents, and solve below.” Questions 1-5 listed below have models showing each fraction that must be matched to the correct fraction equation. Question 1: "\frac{1}{3\times5}" Question 2: \frac{3}{4}\times\frac{2}{3}, Question 3: \frac{4}{5}\times3 Question 4: \frac{1}{5}\times\frac{3}{4} Question 5: \frac{3}{6}\times4. (5.NF.4a) 

The materials reviewed for STEMscopes Math Grade 5 meet expectations for giving attention throughout the year to individual standards that set an expectation of procedural skill and fluency.

STEMscopes materials develop procedural skills and fluency throughout the grade level. In the Teacher Toolbox, STEMscopes Math Philosophy, Elementary, Computational Fluency, STEMscopes Math Elements, these are demonstrated. “In each practice opportunity, students have the flexibility to use different processes and strategies to reach a solution. Students will develop fluency as they become more efficient and accurate in solving problems.” Examples include:

• Daily Numeracy: Fifth Grade, Activities, Daily Numeracy–Solve It, Procedure and Facilitation Points and Slideshow, students demonstrate procedural skill and fluency as they solve whole number multiplication problems using the standard algorithm. Slide 7, "482\times45" “2. Display the slideshow prompt of the day, and ask students to silently think and solve. Instruct students to give hand signals when they are ready to answer. 3. Call on students to give out answers only. Record student answers on chart paper.” (5.NBT.5)

• Scope 7: Multiply Multi-Digit Whole Numbers, Explore, Explore 1–Standard Algorithm, Math Chat, students engage in procedural fluency with teacher support as they multiply multi-digit numbers using the standard algorithm. “Questions: DOK-2 How is multiplying three-digit numbers by two-digit numbers similar to multiplying three-digit numbers by one-digit numbers? DOK-1 Which place values do you use from each number to find partial products?” (5.NBT.5)

• Scope 14: Numerical Expressions, Explore, Explore 1–Order Matters, Procedure and Facilitation Points, students learn the value of a standard order of operations and how failing to follow the order of operations can change the value of an expression. “1. Share the following scenario with the class: a. Tran volunteers at the animal shelter on the weekends. His job is to feed the dogs. There are 5 big dogs, 6 medium-sized dogs, and 10 puppies. Each of the big dogs eats 3 cups of dog food, each of the medium-sized dogs eats 2 cups of dog food, and 1 cup of dog food is divided equally between two puppies. How much dog food does Tran need each time he feeds the dogs at the animal shelter? 2. Distribute 75 centimeter cubes or snap cubes to each pair. 3. Encourage pairs to use the cubes to solve the problem. 4. As students are working, monitor and check for understanding. Ask questions such as the following: a. DOK-1 How can you figure out how much dog food Tran needs for the big dogs? b. DOK-1 How can you figure how much dog food Tran needs for the puppies? d. DOK-1 how can you find out how much food Tran needs? 5. Tell students to use the whiteboard (or paper) to write an expression that would represent the entire problem and write their solution to the problem (32 cups of food). 6. Have each student pair share their expression with another student pair and discuss their thinking. 7. Write the expression 5\times3+6\times2+10\div2 on the board. Ask questions such as the following: a. DOK-1 What is the root word of evaluate? b. DOK-1 Why do you think we call this process “evaluating” an expression? c. DOK-1 How could we evaluate this expression? 8. Work from left to right evaluating this expression: 5\times3=15, 15+6=21, 21\times2=42, 42+10=52, 52\div2=26, Ask questions such as the following: a. DOK-1 What value did you get initially? b. DOK-2 Why is that value different from the value I just got? 9. Explain to students that sometimes certain parts of expressions need to be grouped together and evaluated first, rather than just necessary to do operations in a certain order other than simply left to right. There are symbols we can use to organize these steps. 10. Write the original expression with parentheses this time: (5\times3)+(6\times2)+(10\div2). 11. DOK-2 Ask students to turn and talk to a partner about what the addition of parentheses does for this expression and how this new version relates to the original problem. 12. Explain to students that there are also rules we can use to organize the steps when solving expressions. These rules make up a standard procedure used in mathematics called the order of operations. 13. Tell students that the first thing to do in the order of operations is to solve what is in parentheses. Ask students the following: a. DOK-1 How are multiplication and division related? 14. Explain that since division is the opposite, or inverse, of multiplication, they create related equations, as in 8\times4=32 and 32\div4=8. Therefore, multiplication and division expressions are done first in the order in which they appear, working left to right. 15. Emphasize that neither is more important than the other, so they are performed in order from left to right. 16. DOK-1 How are addition and subtraction related? 17. Explain that since subtraction is the opposite, or inverse, of addition, they create equivalent equations. In other words, 3+4=7 and 7-4=3. Therefore, addition and subtraction expressions are done next in the order in which they appear, working left to right. Neither one is more important than the other, so they are performed in the order they occur in the expression from left to right. 18. Distribute a Student Journal to each student. 19. Tell students that there is a problem that needs to be solved at each station. Their task is to solve the problem by first using the manipulatives and to then create an expression that represents the problem, using parentheses when needed to get the correct solution. 20. Explain that once they have written their expression, they should evaluate it using the correct order of operations. They should be on the lookout for times when parentheses must be used to ensure the correct order of operations is performed. 21. Assign student pairs to stations. As students are working, monitor and check for understanding. Ask questions such as the following: DOK-1 What expression did you write that represents the problem? DOK-2 Why did you put parentheses around 3 x $9.50? DOK-2 What process did you use to evaluate the expression? b. Station 2: DOK-1 How many bouncy balls does Sam have? DOK-2 What process did you use to find the solution? c. Station 3: DOK-2 How many action figures did the boys get? How do you know? DOK-3 Why did you use parentheses around the first 3 numbers? DOK-1 Were the parentheses necessary? d. DOK-2 Were parentheses necessary? Why or why not? 22. When students have finished, give each pair the two Task Cards. Have them use the 75 centimeter cubes or snap cubes to determine the expression that fits the scenario. Students should then evaluate the expression. 23. As students are working, monitor and check for understanding. Ask questions such as the following: a. DOK-1 How did you decide which expression matched the Cookin’ Up Something Sweet problem? b. DOK-1 How did you decide which expression matched the Extreme Chew problem? 24. After the Explore, invite the class to a Math Chat to share their observations and learning. 25. When students are done, have them complete the Exit ticket to formatively assess their understanding of the concept.” (5.OA.1)

The materials provide opportunities for students to independently demonstrate procedural skills and fluency throughout the grade level. Examples include:

• Scope 7: Multiply Multi-Digit Whole Numbers. Explain, Show What you Know Part 1–Using the Standard Algorithm, students demonstrate procedural skill and fluency of multiplying multi-digit whole numbers using the standard algorithm. “Students should individually complete the Show What You Know activity that correlates with the Explore activity they just completed. Each Show What You Know piece correlates with the same number Explore. For example, Show What You Know Part 1 will allow students to practice the skills they developed in Explore 1. Use the standard algorithm to solve each problem. 386\times34, 634\times62, 219\times87, 427\times51, 588\times44, 187\times73. (5.NBT.5)

• Scope 14: Numerical Expressions, Evaluate, Skills Quiz, Student Handout, Questions 1 and 11, students solve problems involving multiple operations. “Solve the expressions. 1. 7\times(32\div4)-8= ___, Write the statements as numerical equations with symbols. 11. Find 4 more than the quotient of 49 divided by 7.” (5.OA.1)

• Scope 19: Apply Volume Formulas, Explain, Show What You Know-Part 2: Volume of Rectangular Prisms, Student Handout, students find the volume of a rectangular prisms using the volume formula. “The local pet store provides a doggy-boarding service. Each dog that is boarded has a room in the shape of a rectangular prism, and each room has a volume of 160 cubic feet. In the boxes below, construct 2 different doggy rooms with a volume of 160 cubic feet. Include a drawing of each room and label the dimensions. Then choose the one you think has the best design. Explain your reasoning. Doggy Room #1, length = ___ feet, width = ___ feet, height = ___ feet,  volume = ___ cubic feet Doggy Room #2, length = ___ feet, width = ___ feet, height = ___ feet, volume = ___ cubic feet, Which doggy room (rectangular prism) did you choose? Explain your reasoning. ___, How did you figure out the volume of each doggy room so it was equivalent to 160 cubic feet? Explain your reasoning. ___” (5.MD.5b)

The materials reviewed for STEMscopes Math Grade 5 meet expectations for being designed so that teachers and students spend sufficient time working with engaging applications of mathematics.

STEMscopes materials include multiple routine and non-routine applications of mathematics throughout the grade level, both with teacher support and independently. Within the Teacher Toolbox, under STEMscopes Math Philosophy, Elementary, Computational Fluency, Research Summaries and Excerpt, it states, “One of the major issues within mathematics classrooms is the disconnect between performing procedural skills and knowing when to use them in everyday situations. Students should develop a deeper understanding of mathematics in order to reason through a situation, collect the necessary information, and use the mechanics of math to develop a reasonable answer. Providing multiple experiences within real-world contexts can help students see when certain skills are useful.”  

This Math Story activity includes both routine and non-routine examples of engaging applications of mathematics. For example:

• Scope 10: Model Fraction Multiplication, Elaborate, Math Story–Firefighters’ Pancake Supper, students solve both routine and non-routine problems with teacher support. “Read the passage and answer the questions that follow. 2. How much money did the first nine diners pay in all? 4. Based on the passage, how long did the pancake supper last? A. 2 hours and 45 minutes, B. 3 hours and 15 minutes, C. 3 hours and 30 minutes, D. 4 hours and 15 minutes, 5. Captain Addams kept a record of the orders so he would know how many supplies they needed for next year’s supper. Of the 25 families served, \frac{2}{5} bought the all-you-can-eat ticket. All the families who came are listed in the chart. How many families ordered the all-you-can-eat tickets? A 15, B 25, C 35, D 10” (5.NF.4a)

Engaging routine applications of mathematics include:

• Scope 5: Compare Decimals, Engage, Hook–Photo Finish, Procedure and Facilitation Points, students develop application of comparing two decimals with teacher support on routine problems. “Part II: Post-Explore, 1. After students have completed the Explore activities for this topic, show the phenomena video again and repeat the situation. 2. Review the problem and allow students to solve it. 3. Split the class into 6 small groups. Each group needs a resealable bag with the cards from Photo Finish! 4. Tell the students that the riders’ finishing times, in the close group of first finishers, were a little over 54 minutes. They were so close that we have times to the thousandths. They will pull out two times at a time and compare them by placing the correct comparison sign between them. They will also decide who the faster rider would be between the two. 5. Discuss the following:  a. DOK-1 Which place do you look at first when you’re comparing decimals? b. DOK-1 What does a 0 in the thousandths place mean? c. DOK-2 When you were deciding which rider was faster, what did you look at?” (5.NBT.3b)

• Scope 9: Add and Subtract Fractions, Explore, Explore 1–Adding with Unlike Denominators Using Equivalent Fractions, Procedure and Facilitation Points, students develop application with routine problems with teacher support as they use pictorial models to find common denominators to add fractions. “1. Read the following scenario: Your aunt and uncle have a big farm where they grow crops. You enjoy being on their farm, so you have offered to help your uncle and aunt with the chores during the weekends. They have divided their farmland into several different sections. They need your help in determining what fraction of the land is being used for some crops. Can you help? 2. Distribute the copies of the Student Journal to each student, and materials to each group. 3. Invite students to read Scenario 1 together. 4. Explain that your uncle and aunt have divided up an area of land for his corn crop. Ask the following questions: a. DOK-1 What does it mean that \frac{3}{8} of the field is being planted with corn? 5. Have students look at the area planned for planting wheat. 6. Explain that he has divided up an area of land for his wheat crop. Ask the following questions: a. DOK-1 What does it mean that \frac{1}{4} of the field is being planted with wheat? 7. Ask students to discuss in their groups: How can \frac{3}{8} and \frac{1}{4} be added together? 8. DOK-2 Invite students to share what was discussed among groups. 9. Explain to students that they will use manipulatives to come up with equivalent fractions for each fraction in order to create common denominators. 10. Invite them to draw the model and to use a colored pencil to indicate each crop. Ask them to use models to answer the questions in their Student Journal...” (5.NF.1)

Engaging non-routine applications of mathematics include:

• Scope 11: Multiplication Problem Solving Using Fractions, Explain, Show What You Know: Part 1, Area with Fractional Side Lengths engages students in independently solving non-routine problems involving multiplication of fractions. “Problem 3, Emmanuela wants to use half of the wrapping paper to wrap her brother's birthday gift. The dimensions of the wrapping paper are 3\frac{2}{4} inches by 7 inches. Once Emmanuela wraps the gift, what is the area size of the remaining piece of wrapping paper?“ (5.NF.6)

• Scope 20: Graph on a coordinate Plane, Explore 2 - Plotting Shapes, Procedure and Facilitation Points, students develop applications with non-routine problems with teacher support as they plot shapes on a coordinate plane in the first quadrant. “1. Distribute a Student Journal to each student. 2. Distribute a Blueprint and a Furniture Shapes handout to each pair. 3. Read the following scenario: a. Michaela is deciding how to arrange the furniture in her living room. She decides to use graph paper to create a blueprint of the room. She then cuts out shapes, to represent the furniture in her room. This way, she can experiment with different layouts without having to actually move the furniture. With your partner, cut out the shapes, and help Michaela find an arrangement for her furniture. 4. Invite students to discuss the following with their partners before sharing with the class: a. DOK-1 How can Michaela use a grid to help her determine the arrangement of her furniture? b. How can coordinate pairs relate to the furniture position? c. What are some things Michaela needs to take into consideration as she is plotting her furniture position? 5. Have students work with their partners to place the furniture on the Blueprint by cutting out the shapes and looking at the coordinates for each shape. Have them record the coordinates of each corner on the Blueprint. 6. As students collaborate, walk around to  monitor student understanding. 7. Have students complete the activity on their Student Journals. 8. After the Explore, INvite the class to a Math Chat to share their observations and learning. 9. When students are done, have them complete the Exit Ticket to formatively assess their understanding of the concept.” (5.G.2) 

The materials reviewed for STEMscopes Math Grade 5 meet expectations in that the three aspects of rigor are not always treated together and are not always treated separately. There is a balance of the three aspects of rigor within the grade.

All three aspects of rigor are present independently throughout the grade. Examples where instructional materials attend to conceptual understanding, procedural skill and fluency, and application include:

• Daily Numeracy: Fifth Grade, Activities, Daily Numeracy-Solve It, Slide 3 and Procedure and Facilitation Points, students demonstrate procedural fluency of subtracting decimal numbers. Slide 3, "431.4-31.43" Procedure and Facilitation Points, “1. Gather students in a group with a piece of chart paper and a marker. Students should not have anything with them for this activity. 2. Display the slideshow prompt of the day, and ask students to silently think and solve. Instruct students to give hand signals when they are ready to answer. 3. Call on students to give out answers only. Record student answers on chart paper. 4. Ask students to volunteer and to explain the strategies they used to get answers. For numberless word problems, students discuss the actions that occur in the problem. Numbers can be inserted after discussion, and students can solve the problem. 5. As students share strategies, ask the class if they agree or disagree, and provide sentence stems for their responses. a. I agree because . . ., b. I disagree because . . ., c.

During the draft, the 30 Major League clubs will take turns selecting players to play on their team. Once you enter the league and start playing games, a player will earn a batting average for how well they can hit the ball. The batting average is defined by the number of hits divided by at bats. It is usually reported to three decimal places. Baseball coaches want players on their team who have a batting average of .300 or greater. This means that the baseball player can usually hit the ball and get on base 1 out of 3 at bats.Your Task: You and a partner are coaches of MLB teams. Research baseball players and their batting averages, and draft your top 10 baseball players. Compare each player chosen from each round. The greater the number, the better the player. The catch is that one partner can only draft players between the years 1990-2000, and the other partner can only draft players between 2001-2011. Decide which person will draft from which set of years, and then complete your draft picks on the Make Your Picks page. Make sure you don’t choose the same player from another year since baseball players can play baseball for many years in a row. Decide on your team name and what years you will be drafting from and write them below. Then, using the internet, research baseball player batting averages and decide which 10 players you would like to draft. Record their names and their batting averages in the table.”
