In this performance assessment, students will construct triangles using only a pencil, ruler and protractor (or angle ruler), if possible, and decide if there are multiple triangles that can be constructed. This assessment is best used once students have had instruction and practice with constructing triangles using properties of triangles.

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.
