Activities in a unit plan address the "how" of instruction. How are we going to approach the why (big ideas and essential questions) and the what (content and skills) in our curriculum? Unlike standards, where consistency is required for student success, activities should be flexible and personalized for learners. Activities aligned to skills, essential questions and assessments, can be varied to accommodate different teaching styles and student needs. Here Marie describes the 3 layers of assessment and how they are connected to activities in a unit.
