Games are a fun way to learn something new. There is a game called Pyramid in the pack. To play pyramid, you have to collect cards that equal thirteen. Suddenly, I was doing math. I was memorizing that 9 and 4, 8 and 5, 3 and 10, and 6 and 7 all make thirteen. These numbers are now drilled into my head. Did I have to work hard to memorize them? Not really. The game taught me to look for those combinations.
