More Expressions and Equations

Open Up Resources 45 min(s)

Interpret expressions, equations, and solutions with respect to the context they represent. Let's solve harder problems by writing equivalent expressions. Initially students are walked through the steps of writing an expression to describe a situation, using properties to rewrite the expression with fewer terms, writing an equation to represent the situation, solving the equation, and considering the reasonableness of solutions. As they proceed through the lesson, the supports are slowly removed and students work on their own to reason through the problem.
