Problem Solving is often difficult for students. With the new Common Core students are asked to not only solve but tell how they solved it. This is quick activity that asks students to match equations that help them solve the word problems given.
Yes, it is a cut and paste. This is meant to give you a quick look at whether your students know what they "should" do to solve a given problem.
To extend this, you could have students prove their answers by modeling on another sheet of paper. :) This is just a freebie.
