Practice: Adding Tens

This video shows a fun way to practice adding tens using playing cards. I use this game as a math center, or also as a task students can do when they finish early.

The video highlights three strategies to solve to find the sum:
1) Skip Counting by 10's 
2) Adding On with 10's 
3) Using Ones to add 10's

This game is closely related to Tens War. To play Tens War, each partner needs a stack of cards. Simultaneously, the two partners draw 2 cards. Each student determines the sum of her cards. Whoever has the higher sum gets to keep all 4 cards.
