John included a great puzzle:
Hmmmm. This will be the only Math Teachers at Play ever directly after a square and before a cube. (Proof.) Of course, in a 3x3x3 cube, only 26 cubes are visible, so you're really taking the 27th on faith. I guess that makes 26 the third Rubik's Cube number? If 8 is the previous and 56 is the next, what is the fifth Rubik's Cube number? What is the closed form for the nth Rubik's Cube Number?I liked Princess Kitten's post on playing an online game called Cops and Robbers, and from a comment there, I found this cool site - ThinkQuest: "Over 7,000 websites created by students around the world who have participated in a ThinkQuest Competition". I really like seeing math content from kids.
I loved finding out in this post that someone has used a bit of math (or engineering) know-how to help with the difficult situation the people of Haiti are facing.
