Lesson Plan

Learning Objective

Interactively explore set inclusion relationships among mathematical number sets.

Audience and Prerequisites

Designed for Algebra I students in grade 9. Students should have arithmetic fluency and introductory familiarity with algebraic notation.

Suggested Activity

1. Ask students to make a prediction before interacting with controls or moving parameters.
2. Highlight subsets to see which numbers belong to each category and see why integers are rational numbers.
3. Compare the visual model directly with the symbolic algebraic expression.
4. Have students summarize their observations in a single sentence.

Assessment

Students explain why all whole numbers are integers, but not all integers are whole numbers.
