Lesson objective: Fluently identify equivalent equations.

This lesson helps to build fluency with identifying equivalent equations. Tape diagrams and number lines are used here because they support students' understanding of how to informally solve equations. This work develops students' understanding that equivalent equations have the same solution.

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they find the value of the solution to each equation and match equivalent equations.

Key vocabulary:

• equation
• equivalent
• solution
• variable
