This activity begins with some common phrases used in word problems that signify area or perimeter. There is also has a catchy phrase to help students visualize the difference between perimeter and area.
Students then have ten word problems to solve. First they determine if the problem asks for perimeter or area. What words in the problem prove that? They should make a drawing to help prove their work and both should be able to explain the solution.
I suggest reviewing the phrases as a class, then let the students solve the word problems in pairs. I sat in one spot and had each pair show me their solution to each problem. Give one point for a correct answer, one point for an accurate drawing, and one point for a clear explanation. The pair who earns the most points wins!
