Explore ratios and proportions while making funny pictures that make things look wildly bigger and smaller than they really are. Take photos, make measurements, explore the world in a whole new way!

Size Wise

Forced perspective photography is a trick of the camera that can make things look wildly bigger or smaller than they really are. The effect works by arranging things at varying distances in front of the camera. Objects that are further away look smaller. Objects that are closer look bigger. Size Wise uses this camera trick to help you do real-world proportional reasoning while taking photos of your friends.

Ideal for middle and high school classrooms, Size Wise and accompanying curriculum activities address Common Core Math Standards (CCSM) by integrating content, mathematical practices, and delight.
