Math - Pattern Blocks
Interesting puzzles using groups of various numbers of hexagons. For example, a pentahex is a group of 5 hexagons. I don't understand the math, but I think that the object is to fill a 'regular' shape with pentahexes. It appears that the last few pentahexes in the center present the biggest problem. But then.... I could be completely wrong. It's interesting regardless.
