About this worksheet

What students practice

Students model and solve shelter word problems using equations of the forms px + q = r and p(x + q) = r.
Students compare algebraic solution steps with arithmetic strategies for the same word problem.

How to use

Have students show equation-solving steps beside each numerical answer. Discuss how the placement of parentheses changes the order of the arithmetic steps.
