If a rectangle has three columns and four rows, how many squares does it have inside? Learners draw 10 rectangles based on specified rows and columns, counting the number of resulting squares. Keep in mind you may want to explain that they won't always come up with squares as the resulting shapes. This presents a great opportunity to introduce area as a concept. Also multiplying height and width.
