What You’ll Find Inside Each Course
Every grade-level course includes a lesson for each unit of study within that grade. In each session, Mossflower Staff Developers and authors unpack:
The big goals and essential understandings of the unit
Key teaching moves and instructional priorities
Practical planning guidance you can use right away
Differentiation strategies to support all learners
Tips for pacing and preparing materials
We recommend viewing each lesson a few weeks before launching the corresponding unit. Keep your Units of Study materials nearby and take notes as you plan.
