A. Subtraction Flash Cards: Groups 7 and 8
With a partner use your Subtraction Flash Cards to quiz each other on the subtraction facts in Groups 7 and 8. 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 the facts you need to practice at home for homework.
Update your Subtraction Facts I Know chart. Circle the facts you answered quickly. Underline those you were able to figure out. Do nothing to those you still need to learn.
