We will use a square area model to look at multiplying fractions. Example Let’s make the height of our unit square ½. 1 Let’s make the base ¼. Move the second square over the first. The answer is the intersection of the two shadings. Note the unit square is now broken into 8 equal pieces.

Let’s try one more model. Example Remember: Build both Overlap these Read answer
