Volume and Surface Area of Rectangular Prisms Two worksheets 1 - 10.

4.MD.3 - 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.

Here are two different versions of a game where students roll dice to create rectangles and then find the area. In one version students count square units. In the second version they apply the formula for area.
