- A related game is known as '24'. There's a deck of cards, but each one is really
- its own puzzle. Each card has four numbers on it, like 8, 8, 4, 2, and the
- object is to use +,-,*,/ to arrive at the result 24. Some of the number
- combinations are easy (6,4,1,1) and some are really hard (can't think of any).
- But they work: where I worked, students who would normally rush out of class
- to go smoke cigarettes when the bell rang stuck around 'to do just one more' or
- 'to figure THAT one out...it's driving me nuts!' One nice thing is that the goal
- is always the same...make 24...and we see that there are LOTS of ways to do just
- that; 24 isn't _just_ 2 times 12, or 3 times 8, or 4 times 6. Moreover, many of
- the number combinations allow for different solutions...and a few students
- would gloat (justifiably) if they found a more obscure solution, or at least a
- solution that the teacher didn't get.
-
- I don't know where '24' comes from...another teacher had brought the cards to
- schools, and I'm not there anymore. But if anyone out there has info on where to
- order a set of these cards, please it my way.
