A while back one of you got me addicted to Fruit Ninja. And although it is a fun little diversion, it is not really a learning game - and I love when my kiddos play learning games! So, today, I found Factor Samurai!
It is very similar to Fruit Ninja - only you slice composite numbers and try to avoid prime numbers.
You can select from a variety of levels from Grasshopper for beginners (which features smaller numbers) up to Master.
In this instance, would slice the 8 which would in turn break into 2 and 4, and you have to slice the 4 as it is another composite number.
Best part? The app is free at the itunes app store!
Even better part? You can earn extra credit and earn $25 Malloy dollars by showing Mrs. Malloy your high score on your ipod or phone. What teacher not only lets you play apps but tells you to play apps???
