Deal out the fun with cards and math

30 12 2010

If you are looking for something to do over winter break try this fun game I read about at the Exploratorium’s Web site. Take four cards and lay them down so you and your partner can see them. Next flip over the final fifth card. Now your partner can use the first four cards to create equations that equal the fifth card. You earn a point for every number you use in the equations. add up your point at the end of five minutes. Also,  Jacks are worth 11, Queens are worth 12, Kings are worth 13 and Aces are worth 13.

Let’s Pretend these are the first four cards we draw

and this is the fifth card we draw

I would get two points for writing  8+2+10

I would also get two points for writing 5X2=10

I would get Four points for writing (8+12)-(5X2)= 10

If these were the only equations I wrote down I would earn a total of 8 points.

Can you find any more equations? Leave a comment
