Math Instructional Strategies: Geometry
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 lecturebased style, most feature an inquirybased approach.

LectureBased: Concept Introduction
In this video, adult education professor Betsy Popple introduces the geometric concept of area. Learners have difficulty in differentiating between the concept of area and perimeter, so Popple spends a few moments clarifying these terms.

Grades: 13+ 
Inquiry Based: Concept Introduction
In this video, viewers observe as adult education professor Betsy Popple, following an inquirybased instruction model, introduces the main concepts of the day’s lesson on area. She frequently calls upon learners to fill in information, inviting them to investigate their own prior knowledge and understanding of the concept to answer her questions. Learners take ownership and feel a sense of pride mastering this lesson on area as they understand that there is more than one way of looking at a problem.

Grades: 13+ 
InquiryBased: Summarize
In this video, viewers watch as adult education professor Betsy Popple uses inquirybased instruction strategies and examines the various methods her learners have used to find the area of a space. She asks them to summarize for the class the best methods to solve the problem. This helps the learners see that multiplication is the most efficient method to find the area of a rectangle.

Grades: 13+ 
InquiryBased: Partner Practice
In this video, instructor Betsy Popple facilitates as learners work together on a practice problem that involves the formula for the area of a rectangle. Sharing knowledge and helping each other through the process reduces the stress a learner might feel on his or her own.

Grades: 13+ 
InquiryBased: Transfer: Practice Problems
In this video, viewers observe the technique of guided practice as small groups of learners find the areas of compound figures. Guided practice, either in small groups or individually, can increase concept understanding and retention. The instructor's role during guided practice is to allow learners to be challenged and even to struggle, providing guidance only when learners veer into misconception.

Grades: 13+ 
LectureBased: Independent Practice
Learners find the area of a compound shape independently, then review their answers.

Grades: 13+ 
InquiryBased: Extended Thinking
In this classroom example, adult education professor Betsy Popple leads an activity where learners work cooperatively to build their understanding of the lesson’s basic concept—the area of a space. Learners must use what they have just learned about the area of a rectangle to compose and decompose a compound shape and find its area.
