I spend a lot of time following some fine math teachers on Twitter. If you are a math teacher and haven't yet succumbed to this new social media, I highly recommend it.
Start by following Dan Meyer, and then work your way through others that he follows or who follow him. What a Professional Learning Group!! Sue VanHattum (MathMama) showed up in my feed today. She shared this site: http://sciencevsmagic.net/geo/
This site starts you out with 2 points. From there you create circles and attach segments to create certain shapes. It tells you what the minimum number of moves it can be made in and also the max, I think. It is really fun trying to do the minimum! So go forth and have a blast!
This is Sue's "Circle Pack 7". I am impressed!
