Play Subtraction Sacks Activity
Your child will be a whiz at subtraction with this simple kinesthetic learning device. The subtraction sack game will help her to memorize basic concepts of subtraction. She'll also be able to self-test and gain a better understanding of how subtraction works by adding and subtracting counters that she puts in and takes out of a paper sack. It's also a fun game to play!
What You Need:
- Counters (plastic beads, chips or marbles)
- 6 lunch bags (decorated, if you like)
- Index cards
What You Do:
- Ask your child to write one number (0-5) on each bag.
- Have your child write numbers on the index cards. On six cards, write "-0", on five cards, write "-1", on four cards, write "-2", on three cards, write "-3", on two cards, write "-4" and on one card, write "-5."
- Place the amount of counters corresponding to the number on the bag, inside the sack. If a sack has "3" on the front, place three counters in the sack.
- Create a corresponding stack of cards for each bag, based on the number on the front of the bag. For example, if it's bag number 1, place cards, "0" and "-1" into the sack. If it's bag number 4, place cards, "-0, -1, -2, -3, -4" into the sack.
- Encourage your child to draw one card and look at the number.
- Have them remove the amount of counters corresponding from the same bag that corresponds to their card and guess how many counters will still be in the sack.
- Ask her to check her number by looking at how many counters remain in the bag.
- If she got it right, ask her to say a sentence explaining what she did.
- Try practicing this game with your child every evening until she understands subtraction. Make the game more challenging by adding numbers 6-10.
