Good Teacher Website

I just found a good teacher website on the discovery channel website. It makes a bunch of different types of puzzles, like wordsearches, crosswords, math cubes, etc. Also, there is an area of logic puzzles that are nice little warm up, thinker type questions for any age.

The puzzlemaker part of the site is at http://puzzlemaker.school.discovery.com

The site in general is discoveryschool.com

I love sites like this. If anyone else has any other good teacher resources, let me know please. Thanks!
