A. Triangle Flash Cards: Square Numbers

With a partner, use your Multiplication Flash Cards to quiz each other on the multiplication facts for the square numbers. One partner covers the corner containing the highest number. This number will be the product. The second person multiplies the two uncovered numbers.

Separate the used cards into three piles: Facts I Know Quickly, Facts I Can Figure Out, and Facts I Need to Learn. Practice the last two piles again and make a list of facts you need to practice at home for homework.

Circle the facts you know quickly on your Multiplication Facts I Know chart.
