This lesson bundle is a great way to teach students to identify when two expressions are equivalent. This lesson bundle includes a flashback/bellwork, PPT presentation, guided notes, exit slip, and homework assignment. This lesson is congruently aligned with CCSS 6.EE.4
6.EE.4 Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y + y + y and 3y are equivalent because they name the same number regardless of which number y stands for.
