In this interactive, students explore how to use shadows, proportional reasoning, and similar figures to determine the unknown height of an object. The interactive allows students to explore the proportional relationships among the similar triangles formed by upright objects and their shadows at different times of day. The accompanying classroom activity provides guidance for using the interactive as a catalyst for discussing concepts and for incorporating it into whole, group, or individual instruction. This resource is part of the Math at the Core: Middle School Collection.

Explore how shadows, proportional reasoning, and similar figures can help you determine the unknown height of an object in this interactive from KET’s Scale City.
