Paper Models of Polyhedra - Gijs Korthals Altes
Grades
6 to 10tag(s): paper folding (3), visual thinking (11)
In the Classroom
Why not print a pattern onto cardstock or other thick paper. Then project the image (that you printed for your students) onto a projection screen or interactive whiteboard, while students work independently at their seats. Before you pass out the paper copies, have them view the projected image and predict what it will be. These shapes can also serve as creative study aids for all subject areas, especially for students who need engaging ways to review. Have students write key terms and questions on the "faces" before assembling the figures, then "roll" them as a study game, testing each other to define or explain terms.Add your comments below (available only to members) | Become a Member
