If each square has sides measuring two centimeters, what is the area of this shape? Learners find area in five shapes segmented into squares with given sides. Encourage them to use square units in their answers. Next, they do the opposite: given a square and its area, they are asked to determine the measurements of each small square unit within it. Learners work only with whole numbers here, and there are 10 problems. Consider doing this as an all-class warm up or in small groups as it is three pages total.
