This document provides examples of tools for assessing student work: a rubric for teacher assessment, an assessment contract for peer assessment, and a self-assessment target for student self-assessment. The teacher's rubric includes criteria for identifying the problem, selecting strategies, and expressing the solution, each rated on a scale from excellent to poor. The peer assessment contract allows students to assign points and sign off to evaluate partners. The self-assessment target is a circle graph where students mark their performance on different criteria and explain areas for improvement.
