Lesson Plan

Learning Objective

Distinguish between independent variables, dependent variables, parameters, and constants in algebraic equations.

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. Select quadrant cells in the 2x2 grid to explore real-world scenarios illustrating variable roles in formulas.
  3. Compare the visual model directly with the symbolic algebraic expression.
  4. Have students summarize their observations in a single sentence.

Assessment

Given a formula like d = rt, students identify which symbols represent variables, rates, and parameters.
