Krypto - Fun and Challenging Math Game

Krypto is a fun and challenging math game to give your little math wizards a chance to stretch their brains!  You can try the on-line version here (it is self-checking which is nice), or you can grab deck of cards and play with the directions below:

You deal out five cards, then an additional card below. The object is to be first to figure out a way to combine the first five numbers using addition, subtraction, multiplication and division in order to come up with the last number dealt. For example, if the first cards were 6 / 1 / 20 / 7 / 8 and the last card was 5, you could combine them in at least two ways:

6 - 1 = 5 (the 6 and the 1 are used, you proceed with the 5)
20 ÷ 5 = 4 (20 from the original numbers and the 5 from the first step)
8 + 4 = 12 (8 from the original numbers and the 4 from step 2)
12 - 7 = 5 (12 from the previous step and 7 from the original numbers)

8 - 7 = 1
6 - 1 = 5
20 ÷ 5 = 4
4 + 1 = 5

Now try one for yourself: The first five numbers are 1 / 3 / 2 / 8 / 8 and the last is 10.
