I just learned a great game called "Close to Twenty" from the TERC 
Investigations in Number, Data, and Space series. See:

http://www.terc.edu/TEMPLATE/projects/item.cfm?ProjectID=49

"Close to Twenty" can be played several ways, but here are the basics:


Each pair of kids needs a deck of  number cards from 0-10 (each digit
has about four cards: 4 zeros, 4 ones, etc. They also include some
WILD CARDS.) You could use a standard deck with the face cards
removed. Deal out 5 per pair. 

Cooperatively, kids try to find three cards that total close to
twenty. Let's say they get these cards:

       8   2   9   2   4       

They could choose 8 + 9 + 2 = 19. They would then have a score of 1,
because they were 1 number away from 20. If they chose 9 + 8 + 4 = 21,
they would get a score of 1 also, since 21 is 1 away from 20. 

The goal is to get the LOWEST score after 5 rounds.

The recording sheet was set up like this:

                                     SCORE       
       ____+____+____=____           ______
       ____+____+____=____           ______
       ____+____+____=____           ______
       ____+____+____=____           ______
       ____+____+____=____           ______

            TOTAL SCORE              ______

I played it today with a group of kids who loved it. Hope this can
help!

       Susan
