8.AEE.B.6: : Write the equation for a line in slope intercept form y = mx + b, where m and b are rational numbers, and explain in context why the slope m is the same between any two distinct points.

8.AEE.C: : Analyze and solve linear equations and pairs of simultaneous linear equations.

8.AEE.C.7: : Solve linear equations with one variable including equations with rational number coefficients, with the variable on both sides, or whose solutions require using the distributive property and/or combining like terms.

8.AEE.C.8: : Find, analyze, and interpret solutions to pairs of simultaneous linear equations using graphs or tables.

8.AFN: : Algebraic Reasoning: Functions

8.AFN.A: : Define, evaluate, and compare functions.

8.AFN.A.1: : Understand in authentic contexts, that the graph of a function is the set of ordered pairs consisting of an input and a corresponding output.

8.AFN.A.3: : Understand and identify linear functions, whose graph is a straight line, and identify examples of functions that are not linear.

8.AFN.B: : Use functions to model relationships between quantities.

8.AFN.B.4: : Construct a function to model a linear relationship in authentic contexts between two quantities.

8.AFN.B.5: : Describe qualitatively the functional relationship between two quantities in authentic contexts by analyzing a graph.

8.NS: : Numeric Reasoning: Number Systems

8.NS.A: : Know that there are numbers that are not rational, and approximate them by rational numbers.

8.NS.A.1: : Know that real numbers that are not rational are called irrational.

8.NS.A.2: : Use rational approximations of irrational numbers to compare size and locate on a number line.

8.GM: : Geometric Reasoning and Measurement

8.GM.A: : Understand congruence and similarity using physical models, transparencies, or geometry software.

8.GM.A.1: : Verify experimentally the properties of rotations, reflections, and translations.

8.GM.A.2: : Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations.

8.GM.A.3: : Describe the effect of dilations, translations, rotations and reflections on two-dimensional figures using coordinates.

8.GM.A.4: : Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and/or dilations.

8.GM.A.5: : Use informal arguments to establish facts about interior and exterior angles of triangles and angles formed by parallel lines cut with a transversal.

8.GM.B: : Understand and apply the Pythagorean Theorem.

8.GM.B.6: : Distinguish between applications of the Pythagorean Theorem and its Converse in authentic contexts.

8.GM.B.7: : Apply the Pythagorean Theorem in authentic contexts to determine unknown side lengths in right triangles.

8.GM.B.8: : Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

8.GM.C: : Solve mathematical problems in authentic contexts involving volume of cylinders, cones, and spheres.

8.GM.C.9: : Choose and use the appropriate formula for the volume of cones, cylinders, and spheres to solve problems in authentic contexts.

8.DR: : Data Reasoning

8.DR.B: : Collect and Consider Data.

8.DR.B.2: : Collect or consider data using surveys and measurements to capture patterns of association, and critically analyze data collection methods.

8.DR.C: : Analyze, summarize, and describe data.

8.DR.C.3: : Analyze patterns of association between two quantitative or categorical variables and reason about distributions to compare groups.

8.DR.D: : Interpret data and answer investigative questions.

8.DR.D.4: : Interpret scatter plots for bivariate quantitative data to investigate patterns of association between two quantities to answer investigative questions.
