Miriam fell through a trap door into a 9-foot-high rectangular room that measured 4 feet wide by 6 feet long. Suddenly, the room began to fill with water! It stopped when the water was 3 feet deep. Miriam sighed with relief, but her relief didn’t last long. The two 4-foot wide walls of the room began to move, making the room smaller and causing the water level to rise. Every 10 minutes, the walls were 1 foot closer together. To the right is a picture of what the room looked like after 10 minutes, when the 4-foot wide walls had moved 1 foot closer together. What is the approximate height of the water? Show how you found your answer.” Problem 2, “The only way to get out of the room is through the trap door in the ceiling. About how much time will pass before the water lifts Miriam to the trap door? Show your work. Explain how you used representations to help you solve the problem.” This activity provides the opportunity for students to apply their understanding of 5.MD.3, “Recognize volume as an attribute of solid figures and understand concepts of volume measure.”

Materials provide opportunities for students to independently demonstrate multiple routine and non-routine applications of the mathematics throughout the grade level. Independent Problem Solving provides “additional opportunities for children to apply the content they have learned during the section to solve non-routine problems independently. These problems often feature: applying math in the real world, multiple representations, drawing information or data from pictures, tables, or graphs, and opportunities for children to choose tools to support their problem solving.” Examples of independent demonstration of routine and non-routine applications of the mathematics include:

Kha-Minh has a box of 36 square tiles with a side length of \frac{1}{3} inch that she would like to use to make a mosaic. She wants the mosaic to be a rectangle and she wants to use all the tiles. Draw and label two different rectangles that Kha-Minh could make. Are the areas of each rectangle the same? Why or why not?” 

• Independent Problem Solving 4a, “to be used after Lesson 4-9”, students describe and explain what they do with a model and how it relates to the problem situation. Independent Problem Solving Masters, Problem 2, “Angelo’s mom pays him $5 per hour for doing work in the yard. His mom makes him save half of what he earns in a bank account and lets him spend the other half however he wants. Angelo wants to buy himself a pair of sneakers that cost $75. How many hours will Angelo have to work to earn enough money to buy the sneakers? Use the grid to help you model and solve the problem. Angelo will have to work ___ hours to earn enough money to buy the sneakers. Explain how you used the grid to model the problem.”

Materials provide intentional development of MP5 to meet its full intent in connection to grade-level content. Students choose appropriate tools strategically as they work with the support of the teacher and independently throughout the units. Examples include:

• Lesson 5-6, Multiplication of Fraction and Whole Numbers, Focus: Discussing Strategies for Multiplying Fractions by Whole Numbers, Math Journal 2, Problem 5, students choose and use appropriate tools as they multiply fractions and whole numbers. “Solve problems 2-5 using any strategy. Show your work. In a classroom, there are 14 cubbies along a wall. Each cubby is \frac{5}{6} foot wide. How long is the line of cubbies?”

• Independent Problem Solving 2a, “to be used after Lesson 2-8”, Problem 2, students recognize both the insight to be gained and limitations of tools and strategies as they convert measurements. “Jamie has a new fitness tracker. Her tracker gives her a goal of taking 10,000 steps each day. Jamie went for a 4-mile run on Saturday. She estimates that when she runs her stride length (the distance from the toe of one foot to the toe of the other foot) is 4 feet. Did Jamie meet her goal of 10,000 steps by running 4 miles? Choose and use an appropriate tool to help you solve the problem. Explain your answer and describe the tool you used.”

• Independent Problem Solving 3b, “to be used after Lesson 3-12”, Problem 1, students recognize both the insight to be gained and limitations of tools and strategies as they solve problems with fractions. “Write a number story to match the following expression. Then solve your number story. Choose and use an appropriate tool to solve your number story. Describe how you used the tool. (3\div4)+2\frac{1}{8}.”

The materials reviewed for Everyday Mathematics 4 Grade 5 meet expectations for supporting the intentional development of MP7: Look for and make use of structure; and MP8: Look for and express regularity in repeated reasoning, for students, in connection to grade-level content standards, as expected by the mathematical practice standards. 

Each lesson targets one to three MPs. Math Practices are identified for teachers in several places: Pathway to Mastery Correlation to the Mathematical Processes and Practices, Focus, Student Math Journals, Student Reference Book, Independent Problem Solving Masters, and Practice. Materials refer to the Mathematical Practices as GMPs (Goals for Mathematical Practice). 

Materials provide intentional development of MP7 to meet its full intent in connection to grade-level content. Students look for and make use of structure throughout the units as they describe, and make use of patterns within problem-solving as they work with the support of the teacher and independently throughout the units. Examples include

• Lesson 3-2, Connecting Fractions and Division, Part 2, Practice: Math Boxes, Math Journal, Problem 1, students make use of the structure as they explore patterns in multiplying with powers of 10. “Solve a. 4\times10= ___. b. 4\times10^2= ___. c. 6\times10^2= ___. d. 6\times1,000.” Problem 5, “Describe a pattern you noticed in Problem 1.” 

• Lesson 8-12, Pendulums, Part 2, Practice: Using the Quadrilateral Hierarchy, Math Journal 2, Problem 3, students look for and explain the structure within mathematical representations as they answer questions about quadrilateral hierarchy. “a. Classify the shape at the right on the hierarchy. List all of the categories you passed through while you were classifying. b. Explain how you knew when to stop classifying the quadrilaterals. How did you know that the shape couldn't move down into more subcategories?” 

• Independent Problem Solving 2a, “to be used after Lesson 2-8”, Problem 1, students look for patterns or structures to make generalizations and solve problems as they use place value knowledge of base-10. “DeShaun’s mom is a computer programmer. She explained that computers use a base-2 place value system. She showed him the following base-2 place-value chart and numbers written in base 2 and base 10. a. How is the base-2 place-value chart similar to a base-10 place-value chart? How is it different? b. How would you write the number 10 in base 2? Explain your thinking.”

Materials provide intentional development of MP8 to meet its full intent in connection to grade-level content. Students look for and express regularity in repeated reasoning throughout the units to make generalizations and build a deeper understanding of grade level math concepts as they work with the support of the teacher and independently throughout the units. Examples include:

• Lesson 1-9, Two Formulas for Volume, Focus: Finding a Formula for Volume, students use repeated reasoning to generalize the formula V=B\timesh and V=l\timesw\timesh. “Ask students to multiply the area of the base by the height of Prism E and verify that the product is the same as what they found for the volume of Prism E in the Math Message. 12cm^2\times3cm=36cm^3. Ask: What else do we need to know to find the volume? How could we find the number of layers in Prism E without using cubes? Why does this work? Summarize by asking: Why does multiplying the area of the base by height of a prism give the volume? Display the formula V=B\timesh and the formula  V=l\timesw\timesh. Ask: What is the relationship between these two formulas?”

• Lesson 4-10, Folder Art, Solving the Open Response Problem, Math Journal 1, Problem 1, students notice repeated calculations to understand algorithms and look for patterns when they create and apply a rule for enlarging an image on a coordinate grid. “Jake is designing a picture for the cover of his reading folder. He draws a picture of a book on a coordinate grid. After drawing the picture, Jake decides he wants to put a picture of a larger book on his folder. Write a new rule that Jake can use to make the picture of the book larger.”

• Lesson 8-2, Applying the Rectangle Method for Area, Practice: Using a Table, a Rule, and a Graph, Math Journal 2, Problem 2, students evaluate the reasonableness of their answers and thinking as they find a rule that relates to a table. “Organic apples are on sale for $1.50 per pound. Anita started making the table in Problem 1 to show how much different amounts of apples will cost. She thinks of $1.50 as 1.5 dollars. She says, “Each time I add 1 pound of apples, I add another $1.50 to the total cost.” She writes the rule “+ 1” in the Pounds of Apples column and the rule “+ 1.5” in the Total Cost in Dollars column. a. Look at the table in Problem 1. What rule relates the Pounds of Apples column to the Total Cost in Dollars column? b. Why does the rule you found in Part a make sense?”
