Nucleus Learning and Hexa-Trex

Over the past few months I have been working on a project: Nucleus Learning. It is a website mostly for teachers, to discuss educational topics. Also I have created an educational math game and puzzle (sold on the Nucleus Learning website also) called Hexa-Trex. I try to submit a new Hexa-Trex puzzle every day. Take a look at both websites, and pass on the word. Thanks!
