This product is intended to be used in a classroom modeled after Peter Liljedahl’s book Building Thinking Classrooms in Mathematics.

Launch Script: Slide 3-5. This is the mini lesson. It should be quick, 10 minutes.

Consolidation: Slide 6. Wrap up the lesson after tasks. This is like a second mini lesson. Have students gather around and possibly walk the room to show varying strategies used by classmates.

Notes: Slides 7-8. This page is intended to be printed for students to write on and glue into journals or hole punched for a notebook.
