In this performance assessment, students will evaluate expressions at specific values of their variables including expressions that arise from formulas used in real-world problems and those involving whole number exponents. Specifically, students will be asked to solve three problems given the formula and the values for the variables in the formula. The problems will include a variety of rational numbers and the exponents will be whole numbers.
This assessment would best be used after instruction on rational numbers, whole number exponents and evaluating expressions.

Below are analytic teacher rubrics. The column on the left shows the dimension that is being measured in the student’s performance. The levels across the top row indicate the performance level in the dimensions. Occasionally all dimensions and performance levels are exemplified by multiple students in a single recording.
