Fifty or Bust!
Note to Families
In this game, players practice adding 10 and another number. The boxes on the playing cards and the record sheet are arranged in tens to make counting, adding, and coloring easier. You can show your child how quickly you can add and color the combinations by counting a stack of 10 first and then adding the ones.
Materials
- Fifty or Bust! pages 1-3
- crayons in 4 or 5 different colors
Instructions
1. Cut out the cards on page 3. Mix them up and place them face-down in a pile.
2. Pick a card, add the amount shown, and color in that many small boxes on your side of the record sheet (page 2). Work from _ left to right and bottom to top.
3. Have your partner take a turn and do the same.
4. Each of you take another turn. Use a different color this time. (Color the 5 stacks inside the box first; the stack outside the box is used only if a player goes bust.)
- Who has more now?
- How many more do you each need to get to 50?
5. Continue to take cards if you think you will not go over 50. Is there a card that would get you closer to 50 without going over?
- You can stop taking cards at any time.
- The winner is the player who gets closest
6. Play the game again, now or later. Save the cards for practicing facts at home.
