######## Evidence for Assessing Learning

######## Performance Tasks:

Demonstrate mastery of objectives through the assessment of graded homework, worksheets, quantitative (numerically graded) rubrics, quizzes, tests, and other formal assessments. Including but not limited to:

- • manipulatives such as number beads and chains to demonstrate solving for • manipulatives such as number beads and chains to demonstrate solving for operations formally assessed by teacher using rubric
