Overview

In this performance assessment, students write inequalities of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Specifically, students will be asked to read scenarios and answer questions using inequalities.

This assessment is best used once the students have had instruction and practice writing inequalities of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem.

NOTE ABOUT ASSESSMENT RUBRICS

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.
