Edit Assessment Plan

Begin writing a unit by establishing what you want students to know and be able to do and planning how you will know "what they know". This Assessment Plan is a general plan (specific assessment instruments are in the teaching procedures); this section should both help you to plan and to give teachers an idea of the varied types of assessment that will be used in the unit. Be sure to include informal checks of understanding, student self-assessment, and authentic assessment. Include pre and post assessment.
