Learning Objectives

Students will solve angle addition sentences using a folded paper model.


(5 minutes)
  • Hold the folded paper teacher model up and ask your class to turn to a neighbor and tell them what it reminds them of and why (i.e. typical ideas include "origami" or "paper airplane").
  • Call on students to share their ideas with the class.
  • Open your model, draw lines along the creases, and announce that the class will be exploring ways to add these angles.
