Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit. Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
Students investigate the relationship between perimeter and area in rectangles -- and then create a way to use three rectangles with different areas.
Students use Google Earth to capture authentic data to answer an intriguing question: how many students could possibly fit on your school's playground?
