  2. 2 How I Think About…Students record their first ideas about the topic.
  3. 3 InvestigationAn Argument-Driven investigation launches the unit.
  4. 4 Concept and practice lessonsStudents build understanding, each cycle closed by a Checking In.
  5. 5 Words I LearnedStudents connect new vocabulary to the ideas.
  6. 6 Targeted Growth StationsEach student gets the next step they need.
  7. 7 How I Think … NowStudents look back at how their thinking changed.
