Multiples of 10
Trying to find sums of groups of multiples is a great way to practice your addition. Be sure to double check your work. If you can clear all of the cards, you win! This game is a great way to have fun while practicing simple addition facts. After you've mastered the directions, invent some new ways to play.
What You Need:
- Deck of cards
What You Do:
- Have your child shuffle the deck. Explain that aces = 1 and all face cards = 10.
- Ask her to create a row of 5 cards, face up. Then place two additional cards face up on top of each of the cards already on the table. There will be a row of 5 cards across, 3 down.
- Set the rest of the cards in a pile to the side.
- The objective of the game is to try to get each row of three cards to equal a sum of a multiple of 10. For example, if one row has a 7, 2, Ace, it is added as 7 + 2 + 1 = 10. Or, 8, 5, 7, is added as 8 + 5 + 7 = 20. If she can find any combo that's a multiple of 10, she can clear the cards and deal out a new row from the deck.
- If she doesn't see any rows with cards that add up to a sum of multiples of 10, encourage her to rearrange the cards to create multiple sums, trying to eliminate as many cards as she can before dealing new cards.
- Continue removing stacks of 3 cards until the entire deck is depleted and all of the stacks of cards are gone.
- To make the game more challenging, try finding sums of different multiple bases. For example, if you use 6 as a base, sums would have to add to 6, 12, 18 and so on. This will encourage the learning of basic multiplication as well!
