Curriculum Expectation: Use algebraic equations with variables to represent changing quantities in relationships

Definition of a Variable: A letter or symbol, such as “a”, “b”, or “x” that represents an unknown number.

Example: Go to the following website and follow the steps below: www.oame.on.ca/CLIPS 1. Click on “start”
2. Under the grade 7 column, click on the “>>” symbol across from “patterning and algebra”
3. Click on “representation of linear growing patterns”
4. Under the clips list, click on “simple linear growing patterns” 5. Under the activity list, click on “Robot Transformer” 6. Follow the on-screen instructions.
