In this performance assessment, students will be asked to describe methods used to set up and solve inequalities with integer values. Specifically, students will be asked to describe inequalities that have been set up from student samples and to identify possible errors in the way the inequalities have been solved.
This assessment might best be used after students have learned about two-step solving involving inequalities with addition, subtraction, multiplication and division with rational numbers.

| 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 Inequalities 1Students can solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are 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.
