Get started with area calculations using a simple shapes activity which could serve to introduce kids to this formula and the concept of units. They partition rectangles into columns and rows to determine the area based on the resulting squares. Keep in mind that learners may not end up with squares per say (could be rectangles) inside these shapes; clarify this beforehand to avoid confusion. Also, the second question calls a rectangle a square. Encourage new geometers to figure out more efficient ways to calculate the units, incorporating multiplication if possible.
