Focus and Coherence: The instructional materials are coherent and consistent with "the high school standards that specify the mathematics which all students should study in order to be college and career ready" (p. 57 of CCSSM).

The instructional materials reviewed for the Glencoe Traditional series partially meet expectations for Focus and Coherence. The materials meet expectations for: attending to the full intent of the mathematical content for all students; spending the majority of time on content widely applicable as prerequisites; and allowing students to fully learn each standard. The materials partially meet expectations for engaging students in mathematics at a level of sophistication appropriate to high school and making meaningful connections in a single course and throughout the series. The materials do not meet expectations for attending to the full intent of the modeling process and explicitly identifying and building on knowledge from Grades 6-8 to the high school standards.

The materials attend to the full intent of the mathematical content contained in the high school standards for all students.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for attending to the full intent of the mathematical content contained in the high school standards for all students.

The materials attend to the full intent of the following standards:

  • N-RN.3: In Algebra 1, Extend 1-4, students complete a table by determining the sum and product of each set of rational numbers. Students use the table to prove that the set of rational numbers is closed under addition and multiplication. In Algebra 1, Extend 7-4 states that “a conjecture can be made that the sum or product of a nonzero rational number and irrational number is an irrational number.” Also in Extend 7-4, the materials provide proofs for a product of a nonzero rational number and an irrational number that is irrational and the sum of a rational number and an irrational number that is irrational.
  • A-REI.4a: In Algebra 1, Lesson 9-5, students write and solve quadratic functions in vertex form by completing the square. In Algebra 1, Lesson 9-6, the derivation of the Quadratic Formula by completing the square is provided within the materials. In the Algebra 1, Interactive Student Guide (ISG), Solving by Using the Quadratic Formula, students follow steps to derive the Quadratic Formula by completing the square.
  • F-IF.4: In Algebra 1, Lesson 1-8, students interpret intercepts of the graph, symmetry, relative extrema, and end behavior from graphs of functions. Students estimate where the function is increasing, decreasing, positive, and negative. In Algebra 1, Lesson 9-1, students determine maximum or minimum values of quadratic equations. In Algebra 2, Lesson 2-2, students examine a table of values depicting the change in height of a kicked football, describe symmetry in the graph of the table, and interpret what the symmetry implies about the ball. In Algebra 2, Lesson 2-3, students estimate the relative maxima and minima using a table of values. In Algebra 2, Lesson 9-5, students find the amplitude and period of trigonometric functions and graph the functions.
  • F-IF.7b: In Algebra 1, Lesson 3-7, students graph step functions and piecewise-defined functions. In Algebra 1, Lesson 3-8, students graph absolute value functions. In Algebra 2, Lesson 2-5, students graph step functions, piecewise-defined functions, and absolute value functions. In Algebra 2, Lesson 5-4, students graph square root functions. In Algebra 2, Lesson 5-5, students graph cube root functions.
  • G-CO.12: In Geometry, Lessons 1-2, 1-3, and 1-4, students work with the definition of constructions to copy a segment using a compass, construct a segment bisector, copy an angle, and construct an angle bisector using a straightedge and compass. In Geometry, Extend 1-5, students follow instructions to construct “a line perpendicular to a given line through a point on the line, or through a point not on the line.” Students use constructions to observe similarities between two constructions. Students also compare perpendicular bisector constructions to segment bisector constructions. In Geometry, Explore 2-7, students use dynamic geometric software to construct parallel lines and a transversal to explore angles. In Geometry, Lesson 2-9, the instructions for constructing parallel lines through a point not on the line is provided within the materials. In Geometry, Extend 3-5, students explore constructions of parallel lines and perpendicular bisectors using a reflective device.
  • G-SRT.5: In Geometry, Lesson 4-2, students prove triangles are congruent using two-column proofs and students calculate missing values in congruent figures. In Geometry, Lessons 4-3 and 4-4, students prove triangles are congruent using Side-Side-Side, Side-Angle-Side, Angle-Side-Angle, and Angle-Angle-Side congruence criteria, and students calculate values using congruent triangles. In Geometry, Lesson 4-5, students write two-column proofs to prove right triangles are congruent. In Geometry, Lesson 7-3, students prove triangles are similar using the Angle-Angle Similarity Criteria and students identify triangles as similar or not similar. If the triangles are similar, students calculate missing measures within each problem. In Geometry, Lesson 7-4, students prove triangles similar using Side-Side-Side or Side-Angle-Side similarity criteria and students use similar triangles to solve real-world scenarios.
  • S-ID.6a: In Algebra 1, Lesson 4-4, students create scatter plots to determine a relationship between the variables in a set of data and draw a line of best fit to create an equation in slope-intercept form best representing the data. In Algebra 1, Lesson 4-6, students write regression equations to represent data and use the equations to make estimations.

The materials do not attend to the full intent of the following standards:

  • F-LE.3: In Algebra 1, Extend 9-8, students determine if a table of values represents a linear, quadratic, or exponential regression equation. Students are given instructions on how to use a graphing calculator to determine the regression equations. Students are not provided an opportunity to observe that a quantity increasing exponentially will eventually exceed a quantity increasing linearly or quadratically.

The materials attend to the full intent of the modeling process when applied to the modeling standards.

The instructional materials reviewed for the Glencoe Traditional series do not meet expectations for attending to the full intent of the modeling process when applied to the modeling standards. The instructional materials do not include some aspects of the modeling process across the series and students do not complete the entire modeling cycle independently due to excessive scaffolding. While aspects of the modeling process are present within the series, students do not make assumptions or develop their own solution strategies. Students analyze application problems and real-world scenarios, but the variables, parameters, units, and/or equations are frequently identified within the problems. Examples of students not completing the entire modeling cycle include: 

  • In Algebra 1, Chapter 1 Project, Want to be Your Own Boss, students develop a business plan as an entrepreneur. Students research challenges and factors involved in creating a business. Students write expressions representing rent, salary per employee, and other expenses. Students do not formulate their own variables as the materials state, “in terms of months m, employees x, or both months and employees.” Students also write expressions representing operating costs to evaluate costs for months with employees (A-CED.1). After the business plan is complete, students evaluate peer business reports to determine if the plans are valid based on the guidelines given within the rubric and description of the plan. Finally, students report, using presentation software, their business plans to their peers.
  • In the Geometry Interactive Student Guide (ISG), Spherical Geometry, students use a diagram with approximate dimensions of a liquid propane tank containing five gallons of propane when full. Students identify a solid that models the tank in order to use the formula of the solid to calculate volume. The materials state, “Let h represent the height of propane left in the tank at any time and g represent the gallons of propane remaining. If the ratio of h to 14 is always equal to the ratio of g to 5, express h in terms of g” (A-CED.4). Students do not formulate variables independently or make assumptions about the problem. A second diagram of the fuel gauge showing the amount of propane in the tank is given. Students express the angle the pointer makes with the empty marker in terms of the volume of the fuel in the tank, g, and the height of the fuel in the tank, h (G-GMD.3, G-MG.1). Students validate the reasonableness of the answer and compute whether or not there is enough propane for a cookout.
  • In the Algebra 2 ISG, Performance Task, A Complicated Greeting, students use technology to sketch a graph of the function p(t)=[15265t65+152]sin(9π130t)+152p(t)=[\frac{-152}{65}\vert t-65 \vert+152]sin(\frac{9\pi}{130}t)+152. Students determine the maximum height of the Bungee Drop and write a function for the vertical height of a Ferris wheel with a radius of 150 feet and the lowest point at 4 feet. Students do not formulate variables as the materials state, “Write a function for the vertical height h of a point on the wheel at a certain time t such that it starts at a height of 4 feet.” Students calculate the number of times the two rides will reach the same height during three minutes of riding. Students do not make assumptions but are instructed to assume the rides are continuous. Students also do not validate or report their findings (F-TF.5).
  • In Algebra 2, Lesson 8-6, the materials state, “Find a set of real-world data that appears to be normally distributed.” Students use the data to calculate the range of values associated with the distributions. Students do not make assumptions about the data but are told it must be normally distributed. Students also do not validate, report, or interpret the data (S-ID.4).

The materials, when used as designed, allow students to fully learn each standard.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for, when used as designed, letting students fully learn each non-plus standard.

The materials require students to engage in mathematics at a level of sophistication appropriate to high school.

The instructional materials reviewed for the Glencoe Traditional series partially meet expectations for engaging students in mathematics at a level of sophistication appropriate to high school. The instructional materials regularly use age appropriate contexts and apply key takeaways from Grades 6-8, yet do not vary the types of real numbers being used. 

Examples where materials regularly use age appropriate contexts include:

  • In Algebra 1, Lesson 2-2, students write one-step equations representing job occupations. Students are given approximations from the Bureau of Labor and Statistics and write one-step equations representing the number of people employed in production and repair occupations.

Examples where materials do not vary the types of real numbers being used include:

  • In Algebra 1, Lesson 8-1, students add and subtract polynomials. Within the problem sets, students write a polynomial in standard form with a rational coefficient.
  • In the Algebra 1 ISG, Graphing Linear Functions, students interpret tables of linear models. All tables consist of integer x and y values, so students model real-world situations without interpreting or graphing non-integer values.
  • In Geometry, Lesson 9-5, students calculate angle measures and arc lengths using characteristics of secants and tangents. All given angle measures and arc lengths are whole numbers. Students do not calculate using fractions or decimal values.

The materials are mathematically coherent and make meaningful connections in a single course and throughout the series, where appropriate and where required by the Standards.

The instructional materials reviewed for the Glencoe Traditional series partially meet expectations for being mathematically coherent and making meaningful connections in a single course and throughout the series. The materials include meaningful connections in a single course and throughout the series, but the materials also omit some connections in a single course or throughout the series. The materials identify connections within the series by listing prior standards addressed at the beginning of each chapter and lesson and each chapter begins with Then-Now statements connecting prior learning to expected learning for each lesson.

Examples where the materials foster coherence through meaningful mathematical connections in a single course or throughout the series include:

  • In Geometry, Teacher Edition, Lesson 4-7, Track Your Progress, a chart is given with Then-Now statements. Teachers are provided the standards used within the lesson (G-CO.10, G-GPE.4) and the standards connected to the lesson (G-CO.7,8).
  • In the Algebra 2 ISG, Solving Quadratic Equations by Graphing, students graph quadratic equations to find solutions and in the Algebra 2 ISG, Solving by Factoring, students solve quadratic equations by factoring. In the Algebra 2 ISG, Solving by Using the Quadratic Formula and the Discriminant, the materials state, “You have solved some quadratic equations by graphing, by factoring, and by completing the square” (F-IF.8a; A-SSE.2) and students solve quadratic equations by using the quadratic formula.

  • In Algebra 1, Lessons 6-1, 6-2, 6-3, and 6-4, students use substitution, elimination, and graphing to solve systems of equations (A-REI.6). In Algebra 1, Lesson 9-7, the materials state, “Like solving systems of linear equations, you can solve systems of linear and quadratic equations by graphing the equation on the same coordinate plane.” Students make connections between methods of solving systems of linear equations with solving systems of linear and quadratic equations. Students also solve systems of linear and quadratic equations graphically or algebraically (A-REI.7).

Examples where the materials do not foster coherence by omitting some appropriate and required connections in a single course or throughout the series include:

  • In Geometry, Lessons 3-1, 3-2, and 3-3, students transform figures by reflection, rotation, translation, and dilation (G-CO.A,B). In Algebra 2, Lesson 2-6, students perform and describe transformations of parent functions (F-BF.3). There is no connection made to the transformations in the previous course.
  • In Algebra 2, Lesson 3-2, students solve quadratic equations by graphing (A-REI.4). There is no connection made to Algebra 1, Lesson 9-3, where students also solve quadratic equations by graphing. Many of the examples in both lessons are identical.
  • In Algebra 1, Lesson 9-5, students solve quadratic equations by completing the square (A-REI.4b). In Geometry, Lesson 9-7, students create equations of circles by completing the square (G-GPE.1). In Algebra 2, Lesson 3-5, students solve quadratic equations by completing the square involving real and complex solutions (A-REI.4b).

The materials explicitly identify and build on knowledge from Grades 6--8 to the High School Standards.

The instructional materials reviewed for the Glencoe Traditional series do not meet expectations for explicitly identifying and building on knowledge from Grades 6-8 to the High School Standards. The instructional materials do not allow students to extend their previous knowledge by making  connections between Grades 6-8 and high school concepts.

Throughout the series, the materials provide Track Your Progress sections in the Teacher Edition. These include the Mathematical Background needed for the lesson as well as a Then-Now-Next chart. The chart provides previous standards connected to the lesson, standards taught within the lesson, and standards being taught in the future. Some of the standards from Grades 6-8 are listed, but standards from Grades 6-8 are often presented as new standards for students to learn. The following examples are examples where the materials do not explicitly identify and/or build upon standards from Grades 6-8:

  • In Algebra 1, Lesson 1-2, students use order of operations to evaluate equations and simplify expressions. There is no connection made to students applying properties of operations to expand expressions (7.EE.1). Order of operations is presented as a new standard and students are given the steps of the order of operations within a Key Concept chart.
  • In Algebra 1, Lessons 2-2, 2-3, and 2-4, students solve one-step, two-step, and multi-step equations in one variable. There is no connection made to students solving equations in one variable (8.EE.7).
  • In Algebra 1, Lesson 5-1, students write and solve inequalities with one variable. There is no connection made to constructing simple inequalities in one-variable (7.EE.4).
  • In Algebra 1, Lessons 6-1 through 6-4, students solve systems of equations using graphing, substitution, or elimination. There is no connection made to 8.EE.8 in which students solve pairs of simultaneous linear equations.
  • In Geometry, Lessons 3-1, 3-2, and 3-3, students perform transformations on geometric figures. There is no connection made to the effects of transformations on two-dimensional figures (8.G.A).
  • In Geometry, Lesson 8-2, students use the Pythagorean Theorem and its converse to solve problems. There is no connection made to 8.G.7 in which students apply the Pythagorean Theorem and its converse to calculate unknown side lengths of right triangles. Within the same lesson, students prove the converse of the Pythagorean Theorem and students are provided with a proof of the Pythagorean Theorem using geometric mean. There is no connection made within the lesson to proving the Pythagorean Theorem (8.G.6).

Rigor & Mathematical Practices

Criterion 2.1: Rigor

07/08
Rigor and Balance: The instructional materials reflect the balances in the Standards and help students meet the Standards' rigorous expectations, by giving appropriate attention to: developing students' conceptual understanding; procedural skill and fluency; and engaging applications.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for Rigor and Balance. The materials provide students opportunities to independently demonstrate conceptual understanding, procedural skills, and application, and the materials partially balance the three aspects of Rigor.

Indicator 2A

Attention to Conceptual Understanding: The materials support the intentional development of students' conceptual understanding of key mathematical concepts, especially where called for in specific content standards or clusters.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for developing conceptual understanding of key mathematical concepts, especially where called for in specific standards or cluster headings.The instructional materials develop conceptual understanding and provide opportunities for students to independently demonstrate conceptual understanding and most of the opportunities for students to develop conceptual understanding are located in the Interactive Student Guides (ISG). 

Examples of the materials developing conceptual understanding and students independently demonstrating conceptual understanding include: 

  • A-APR.1: In the Algebra 1 ISG, Adding and Subtracting Polynomials, students compare the behavior of polynomials to integers under addition and subtraction and write a conjecture describing closure under addition and subtraction of polynomials. In the Algebra 1 ISG, Multiplying a Polynomial by a Monomial, students determine if polynomials are closed under multiplication by proving the product of a monomial and a polynomial is a polynomial.
  • A-REI.11: In the Algebra 2 ISG, Solving Polynomial Equations, students use a graphing calculator to sketch f(x)=x42x5f(x)=x^4-2x-5 and g(x)=x6+3x2+3g(x)=-x^6+3x^2+3 and estimate the points of intersection. The materials state, “Explain the algebraic significance of a point of intersection on the graphs of f(x) and g(x).” Within the same lesson, students critique the reasoning of a student who claims two functions have no solutions due to no intersections and explain the reasoning behind their critique.
  • F-LE.1: In the Algebra 1 ISG, Analyzing Functions with Successive Differences, students complete a table of values for a linear function, a quadratic function, and an exponential function. Students compare charts with other students in order to make conjectures about each function. Students “look for connections between different function types and their successive differences and successive ratios.” Throughout the lesson, students explain connections between the type of function and the model of the scenario.
  • G-SRT.6: In the Geometry ISG, Trigonometry, students explore ratios in similar triangles by using Geometer’s Sketchpad. Students explain what they notice about side lengths when changing the size of the triangle. Students also examine two triangles with different side lengths and congruent angles to “explain why BCAB=EFDE\frac{BC}{AB}=\frac{EF}{DE}. What does this tell you about any right triangle with a 37° angle.” From the task, students determine trigonometric ratios for right triangles with an acute angle.
  • S-CP.5: In the Geometry ISG, Conditional Probability, students are given a scenario where event A represents owning a house and event B represents owning a car. Students must determine if the events are independent or dependent as well as compare the P(A|B) to P(B|A). After making the comparison, students must explain their reasoning using precise vocabulary.
Indicator 2B
02/02
Attention to Procedural Skill and Fluency: The materials provide intentional opportunities for students to develop procedural skills and fluencies, especially where called for in specific content standards or clusters.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for providing intentional opportunities for students to develop procedural skills, especially where called for in specific content standards or clusters. The instructional materials develop procedural skills throughout the series and students independently demonstrate procedural skills across the courses. 

Examples of the materials developing procedural skills and students independently demonstrating procedural skills include: 

  • A-SSE.2: In Algebra 1, Lesson 8-5, students rewrite quadratics into equivalent factored forms. Students use the distributive property and factoring by grouping in order to rewrite quadratic expressions and polynomials.
  • A-APR.3: In Algebra 2, Lesson 4-9, students factor polynomials to calculate the number and type of roots and sketch graphs based on the zeros. Students also match an appropriate graph to a given zero.

  • G-GMD.3: In Geometry, Lesson 11-2, students calculate the volume of different prisms, cylinders, and composite solids. In Geometry, Lesson 11-2, Preparing for Assessment, students calculate the volume of various three dimensional shapes.
Indicator 2C
02/02
Attention to Applications: The materials support the intentional development of students' ability to utilize mathematical concepts and skills in engaging applications, especially where called for in specific content standards or clusters.

The instructional materials reviewed for the Glencoe Traditional series meet expectations for supporting the intentional development of students’ ability to utilize mathematical concepts and skills in engaging applications, especially when called for in specific content standards or clusters. Students engage in routine and non-routine applications of mathematics throughout the series and demonstrate the use of mathematics flexibly in a variety of contexts.

Examples of students engaging in routine and non-routine application of mathematics and demonstrating the use of mathematics flexibly in a variety of contexts include: 

  • F-TF.5: In Algebra 2, Lesson 9-6, students solve a non-routine application by writing a trigonometric function to model the movement of carousel horses according to a list of provided constraints. Students also consider how to make changes to their function if the characteristics of the carousel change.
  • G-SRT.8: In the Geometry ISG, Angles of Elevation and Depression, students use trigonometric ratios to write a formula to calculate the height of a rock formation knowing the height of a geologist is 1.8m. Students also calculate the width of a lake given a helicopter with an altitude of 450 meters and two angles of depression.
  • G-MG.2: In Geometry, Lesson 11-7, students determine a solid with the greatest density when given certain conditions. The materials state, “A cylinder and a sphere have the same mass. The height of the cylinder is equal to its radius. The radius of the sphere is equal to the radius of a cylinder.” Students determine the greater density and explain their reasoning.
  • S-ID.2: In the Algebra 1 ISG, Comparing Sets of Data, students plan a vacation based on weather history. Students examine two charts showing the rainy days over a 10-year period. Students use the data to “determine the shape of each distribution and use the appropriate statistics to find the center and spread for each set of data.” Students provide advice on the better place to visit for vacation and explain their reasoning.
Indicator 2D
01/02
Balance: The three aspects of rigor are not always treated together and are not always treated separately. The three aspects are balanced with respect to the standards being addressed.

The instructional materials reviewed for the Glencoe Traditional series partially meet expectations that the three aspects of rigor are not always treated together and are not always treated separately. All three aspects of rigor are present in the materials, but there is over-emphasis of one of the three aspects of rigor. The majority of the lessons in the materials address procedural skills and some address application. Students complete series of examples addressing procedural skills followed by an application. Students also complete Check Your Understanding, Practice and Problem Solving, and Higher Order Thinking (HOT) Problems. The ISG develops conceptual understanding and students also complete a practice section within the ISG focused on conceptual understanding.

Examples of the materials over-emphasizing procedural skills include:

  • In Algebra 1, Lesson 5-3, and the ISG, Solving Multi-Step Inequalities, students write and solve multi-step inequalities (A-CED.1; A-REI.3). Most of the examples in the lesson involve procedural skills and, in the Check Your Understanding and Practice and Problem Solving, procedural skills are also primarily addressed with an application. In the ISG, students complete problems that develop conceptual understanding by justifying their steps, critiquing the reasoning of a student, describing a method, and explaining if the solution is reasonable.
  • In Algebra 1, Lesson 7-5, the materials address graphing exponential functions and identifying data that is exponential (F-IF.7e; F-LE.5). Three of the four examples emphasize procedural skills and Example 3 is an application for students to graph and interpret. In Check Your Understanding and Practice and Problem Solving, most of the problems develop procedural skills and there are a few, real-world applications. The corresponding ISG lesson, Exponential Functions, states the objectives are “creating exponential functions to model relationships between quantities” and “graph exponential equations on a coordinate plane.” Students develop conceptual understanding in the ISG lesson by writing exponential equations, interpreting different parts of the equation, using data in real-world context to explain why an exponential equation should be used, graphing exponential equations, and interpreting parts of the graphs in context.
  • In Geometry, Lesson 3-1, and the ISG, Reflections, students draw and identify reflections (G-CO.4,5). In the lesson, there are five examples, four of which emphasize procedural skills. Example 2 uses real-world context to minimize distance using a reflection. In the Check Your Understanding and Practice and Problem Solving, procedural skills are utilized in the majority of the problems. In the ISG, students develop the definition of reflection and the rules for mapping reflections through conceptual understanding and students construct arguments while identifying transformations that are reflections. The Practice in the ISG emphasizes conceptual understanding as students describe, critique, and construct arguments.
  • In Geometry, Lesson 7-6, and the ISG, Parts of Similar Triangles, students prove theorems about triangles, use congruence and similarity criteria for triangles to solve problems and prove relationships in geometric figures (G-SRT.4,5). In the lesson, two of the three examples emphasize procedural skills and the third example is an application. The example problems address finding side lengths with one correct solution and answer. In Check Your Understanding and Practice and Problem solving, students utilize procedural skills to find the value of a variable (side length) in the majority of the problems. In the ISG, students utilize Geometer’s Sketchpad to investigate parts of similar triangles and find patterns, make conjectures, describe steps to be used in a proof, calculate, and explain their solutions.
  • In Algebra 2, Lesson 4-6, students solve polynomial equations (A-CED.1) using procedural skills. Five of the six examples emphasize procedural skills and the sixth example is an application. In Check Your Understanding and Practice and Problem Solving, the majority of the problems require a numerical answer. As with each lesson, there are HOT Problems with five questions. In the ISG lesson, Solving Polynomial Equations, students examine a polynomial function in a real-world context, graph the function, and explain various aspects of the polynomial. Students use a graphing calculator to graph polynomials in order to approximate solutions. Also in the ISG lesson, students “explain the algebraic significance of a point of intersection on the graphs of f(x) and g(x)” and relate that to solving the equation f(x) = g(x). In Practice for the ISG lesson, students explain their reasoning, explain different methods for solving polynomials, and find two different equations given a graph.

In Algebra 1, Lesson 10-2, students create dot plots, bar graphs, or histograms based on a given data set. Students do not analyze the relationships within the models or solve problems based on the models.
  • MP6: In Geometry, Lesson 3-1, the materials state, “The image of a point reflected in a line is always, sometimes, or never located on the other side of the line of reflection.” Students do not attend to precision as they choose the correct word to complete the statement.
  • MP7: In Geometry, Lesson 2-9, students calculate the value of x when given expressions of two corresponding angles. Students identify the angles as acute, right, obtuse, or not enough information. Students do not look for and make use of structure. 
  • MP8: In Algebra 1, Lesson 9-8, students select tables of data to best model exponential equations. Students select appropriate models instead of evaluating the reasonableness of their results.

Students communicate precisely by justifying answers using definitions of symmetry and students describe reflectional and rotational symmetry of figures. Students also attend to precision by using correct terminology to communicate the types of symmetry.
  • In the Geometry ISG, Congruence, students determine if figures are congruent. Students “use precise language to justify your answer.”
  • In the Algebra 2 ISG, Distribution of Data, students draw a histogram to represent data on the wingspan of insects. Students describe the shape of the data set and what it means for the data to be skewed. Students also communicate precisely to explain what the data shows about the wingspan.

  • In Algebra 2, Lesson 6-1, students reason to write functions representing situations. Students determine if the function represents exponential growth or an exponential decay, identify the growth factor, and graph the function.

Examples of MP3 being used to enrich the mathematical content and intentionally developed to reach the full intent of the MP include:

  • In Algebra 1, Lesson 2-5, students perform an error analysis on the work of fictional students. Students determine if the fictional students are correct and explain any error in their reasoning.
  • In the Geometry ISG, Proving Triangles Congruent ASA, AAS, the materials state, “Raj says that he can draw two triangles that have two sides and a nonincluded angle congruent and that the two triangles are congruent.” Students agree or disagree with Raj justifying his claim with the SSA Congruence Theorem and provide a counterexample to disprove Raj’s claim.
  • In the Algebra 2 ISG, Designing a Study, students analyze a study on cat food and weight gain. Students calculate the mean weight of the cats and determine if the difference in weights is significant or not. Students construct an argument to explain their reasoning.

The instructional materials reviewed for the Glencoe Traditional series partially meet expectations for supporting the intentional development of modeling and using tools (MPs 4 and 5), in connection to the high school content standards. The majority of the time MP4 is used to enrich the mathematical content and is intentionally developed to reach the full intent of the MP, but the materials do not not develop MP5 to its full intent as students do not choose appropriate tools strategically.

Examples of MP4 being used to enrich the mathematical content and intentionally developed to reach the full intent of the MP include:

  • In Algebra 1, Lesson 9-5, students determine the dimensions of a painting after it is increased in size. The materials state, “the increase in the length is 10 times the increase in the width.” Students draw a model or use an algebraic model to calculate the new dimensions of the painting.
  • In Geometry, Lesson 9-7, students write the equation of a circle to represent different scenarios.
  • In Algebra 2, Lesson 1-7, students model systems of inequalities by graphing in order to calculate multiple possible solutions.
