In fact here's a game to try right away!
By Elaine

MBK/4thm
Here’s one game we use that’s related to addition, subtraction, and place value, and the best part is that my students love it!

“CLOSE TO 100”
MATERIALS:
*NUMERAL CARDS (one set for each pair of students)
(There’s a blackline master for making this set of cards, but I just cut 3 by 5 index cards in half and write the numbers on them with a colorful marker. You’ll need 4 cards for each of the following: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, Wild Card. That’s a total of 44 cards in a deck.)
*SCORE SHEET (1 for each student)
Here is an example of what a score sheet looks like.

Round 1. ___ ___ + ___ ___ = _____ Score _______
Round 2. ___ ___ + ___ ___ = _____ Score _______
Round 3. ___ ___ + ___ ___ = _____ Score _______
Round 4. ___ ___ + ___ ___ = _____ Score _______
Round 5. ___ ___ + ___ ___ = _____ Score _______
Total Score ________
PLAYERS: 1, 2, or 3

HOW TO PLAY:

1. Deal out six Numeral Cards to each player.

2. Use any four of your cards to make two numbers. For example, a 6 and a 5 could make either 56 or 65. Wild Cards can be used as any numeral. Try to make numbers that, when added, give you a total that is close to 100.

3. Write these two numbers and their total on a SCORE SHEET. For example: 42 + 56 = 98.

4. Find your score. Your score is the difference between your total and 100. For example, if you total is 98, your score is 2. If your total is 105, your score is 5.

5. Put the cards you used in a discard pile. Keep the two cards you didn’t use for the next round.

6. For the next round, deal four new cards to each player. Make more numbers that come close to 100. When you run out of cards, mix up the discard pile and use those cards again.

7. Five rounds make one game. Total your scores for the five rounds. LOWEST score wins!

Scoring Variation:
Write the score with minus and plus signs to show the direction of your total away from 100. For example: If your total is 98, your score is --2. If you total is 105, your score is +5. The total of these two scores would be +3. Your goal is to get a total score for five rounds that is close to 0.

Another variation:
"Close to 1000" Take it to a higher level by dealing 8 cards to each player. Students use 6 of the 8 cards to try to make two 3-digit numbers that are as close as possible to 1000. Scoring is the same as "Close to 100."

Try it! I think you'll love it!
