EngageNY 60 min(s)

In this lesson, students solve word problems involving the perimeter of rectangles and other types of polygons. (For example, "Mrs. Kozlow put a border around a 5-foot by 6-foot rectangular bulletin board. How many feet of border did Mrs. Kozlow use?") They draw a picture of the situation, label the information they know, determine other essential information, and write an expression to calculate the answer.
