Reasoning about Solving Equations (Part 2)

Open Up Resources 40 min(s)

Make connections between solving an equation of the form and finding an unknown weight on a balanced hanger diagram. Understand why a balanced hanger with multiple copies of a group of weights can be represented by equations of both forms and p(x + q) = r px + q = r p(x + q) = r Let's use hangers to understand two different ways of solving equations with parentheses. Learning targets: students can explain why some balanced hangers can be described by two different equations, one with parentheses and one without and how a balanced hanger and an equation represent the same situation.
