Use DPP item F as a Problem of the Week.
Remind students that a square is a special kind of rectangle. Give students grid paper and suggest they draw several copies of the figure and mark the rectangles they find with a colored pencil or marker. Before they start work, you could give them a ballpark figure of the answer, such as about 25 rectangles. Challenge them to find as many as they can.
