A.4 Create equations that describe number or relationships. 4 - Rewrite formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

36, 37

2

A.1 Understand solving equations as a process of reasoning and explain the reasoning. 1 - #Explain each step in solving an equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.

9.5

D.12 Represent and solve equations and inequalities graphically. 12 - "Graph a linear inequality (strict or inclusive) in two variables; graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes."

12, 13

2.5

A.2 Understand the concept of a function and use functions notation. 2 - Use function notation, evaluate functions, and interpret statements that use function notation in terms of a context.

26, 30, 33, 35

7

B.4 Interpret functions that arise in applications in terms of the context. 4 - For functions, including linear, quadratic, and exponential, that model a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing or decreasing, including using interval notation; maximums and minimums; symmetries

B.5 Interpret functions that arise in applications in terms of the context. 5 - Relate the domain of a function to its graph and find an appropriate domain in the context of the problem.

C.8 Analyze functions using different representations. 8 - " Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function."

1.5

A.1 Summarize, represent, and interpret data on a single count or measurement variable. 1 - Represent data with plots on the real number line (dot plots, histograms, and box plots).

2

3

A.2 Summarize, represent and interpret data on a single count or measurement variable. 2 - Use statistics appropriate to the shape and context of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

3

3

A.3 Summarize, represent, and interpret data on a single count or measurement variable. 3 - Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
