The Unit Overview is a clear, concise, focused synopsis of the unit and includes interesting, succinct descriptions of the learning activities in support of the objectives.

The Guiding Sub-questions are related, relevant, and connected to exploring the Essential Question. They are higher level questions and are specific enough to guide the work of the unit. (Subquestions must be entered one at a time and updated . . . they are numbered automatically.)

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.

Classroom preparation for implementation includes notes on preparing the classroom (i.e. ideas for organization, flexible grouping, technologies needed, etc.).

Preparation for students includes notes on preparing the learner such as possible misconceptions students may have, ideas of pre-exposure for learners, and prerequisite lessons. It includes ideas for accelerated learning.

Unit Resources include general, global resources that might include bookmarks, books, periodicals, media and software. URLs need to be provided for each resource to identify a source from which it can be obtained. Resources might include those purchased as part of an adoption. More specific resources will be referenced within the teaching procedures.
