# Rewrite Expressions

Videos and lessons to help Grade 7 students understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related.

For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”

Common Core: 7.EE.2
