Included in the Teacher Materials is an overview document called the Unit Plan, that summarizes the storyline of the unit and provides an outline for each of the learning sequences within the unit, highlighting key information. For each lesson sequence in the unit, the Teacher Materials also include step-by-step guidelines for enactment.
