In this performance assessment, students will be using four operations and grouping symbols to simplify numeric expressions. Specifically, students will be asked to identify errors in the way an expression may have been simplified. Next, they will add parentheses in the expressions that were incorrect to make them equivalent.
This assessment should be given after students have learned order of operations. (Students do not need to understand how to simplify exponents.)

| Big Ideas | Competencies |
|---|---|
A. Understanding and Applying Number SystemsStudents understand that numbers hold value and can choose the appropriate representations and algorithms to reason quantitatively, abstractly, and efficiently. |
Properties of Operations 2Students can apply the properties of operation to generate or identify equivalent 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.
