CCSS Math Standard: 6.EE.4

Apply and extend previous understandings of arithmetic to algebraic expressions. 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.

Parentheses: How big of a change can they make!?

Once students understand the order of operations, they often just get stuck doing increasingly difficult practice problems. That’s a sure-fire way to squelch learning, though. Here, students determine where to place parentheses to make the greatest change in an expression.
