Lesson objective: Fluently match equations with tables, graphs, situations, or patterns with the same relationship while playing a game.

This lesson helps to build fluency with independent and dependent variables. Tables, graphs, scenarios, and patterns are used here because they support the understanding of how independent and dependent variables create an equation. This work develops students' understanding that we can model the relationship between independent and dependent variables using equations.

Students engage in Mathematical Practice 3 (Construct viable arguments and critique the reasoning of others) as they play games with matching representations of equations and need to be able to defend their choices with their classmates.

**Key vocabulary:**

- dependent variable
- equation
- independent variable
- representation
