In this performance assessment, students will write and solve one-step equations using inverse operations involving positive, rational numbers. Specifically, students will create and solve five equations. This assessment provides students with seven different scenarios to demonstrate their understanding of creating and solving single-step equations. Finally, students will create their own scenario, write an equation, and then solve their equation. Lunchroom and recess themes are utilized to engage students. Then, students will reflect on how they solved the problems.
Students should have had instruction on solving single-step equations and translating verbal descriptions into equations before this assessment is used.

| Big Ideas | Competencies |
|---|---|
B. Operations and Algebraic ThinkingStudents can use mathematics to analyze and evaluate historical, political, economic, scientific, and social problems and make conjectures about possible solutions. |
Solve Linear Equations 1Students can solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers. |
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.
