Ø Set up, solve, and use proportions to identify an unknown number or to make predictions from data. Ø Use direct and indirect variation equations, tables, and their graphs to solve real-world problems, including problems involving units of measure and rates. Ø Solve equations using the “undoing” method

*A1.1.A Select and justify functions and equations to model and solve problems.
*A1.2.B Recognize the multiple use of variables, determine all possible values of variables that satisfy prescribed conditions, and evaluate algebraic expressions that involve variables. A1.2.D Determine whether approximations or exact values of real numbers are appropriate, depending on the context, and justify the selection. *A1.3.B Represent a function with a symbolic expression, as a graph, in a table, and using words, and make connections among these representations. *A1.2.B Recognize the multiple uses of variables, determine all possible values of variables that satisfy prescribed conditions, and evaluate algebraic expressions that involve variables. *A1.4.A Write and solve linear equations and inequalities in one variable.
