# Math Instructional Strategies: Geometry

Special Collection

This collection of resources was produced by KET for adult educators. Videotaped segments taken in actual classroom settings provide examples of strategies for teaching geometry in the adult education classroom.

In these segments, learners are active participants in the lessons, often collaborating in small groups to find measurements for area, perimeter, missing dimensions, and compound shapes. You will also find techniques for moving learners from concrete to abstract methods of solution.

While some lessons are presented in traditional lecture-based style, most feature an inquiry-based approach.

Learners have been asked to find the area of a square when only one dimension is given. Inquiry is used to teach number operations.
