This is a lesson for learning about area and perimeter of rectangles. This corresponds to "College and Career Ready" standard (3.MD.7a) -- Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths. (I was not able to find that standard here.)
