Use DPP item A to practice the addition facts in Groups C and D. Students will need the Triangle Flash Cards: Groups C and D , an envelope with a paper clip, and their Addition Facts I Know chart from Unit 1. After students sort the cards, they should clip and store the facts they know quickly and continue to practice the facts they do not know. Students can take the cards home to practice with their families.

Ongoing Assessment

A. Triangle Flash Cards: Groups C and D

With a partner, sort the flash cards into three piles: Facts I Know Quickly, Facts I Can Figure Out, and Facts I Need to Learn. Circle the facts you know quickly on your Addition Facts I Know chart. Clip cards in the Facts I Know Quickly pile together and place them back into the envelope. Practice the facts in the last two piles again.
