I made a problem solving flip book for Geometry riddles. Students use the attributes of a plane shape or 3D figure to write a riddle in small groups. They present the riddle to the class for their classmates to solve.
I’m having problems linking to the flip book at prometheanplanet.com. So I uploaded it to here to Google Docs.
