Folding Surface Area

Topic: Mathematics
Title: Folding Surface Area  (5th-8th grade)
Presenter: Ruth Vanderpool Ph.D. Lecturer at University of Washington Tacoma

Activity: This activity runs about 60 minutes and builds intuition for surface area and volume with modular origami (paper folding).   Students are shown how to construct Sonobe units and build their own cube.  The surface area and volume can be computed with measuring devices or mathematical theory depending on what the teacher would like to emphasize.  The Sonobe units can then be used to construct other geometric three dimensional objects whose surface area and volumes are easy to compute and analyze.
