The Web Catcher

The Math Cats web site offers several activities to explore, ideas for and examples of math crafts, and a great section on make-at-home math manipulatives. It has a simple, folksy feel, a welcome contrast to much of the slick stuff you see on the web. Most of the activities include some guided discussion of how to explore and interact. The activities provide feedback rather than corrections, so the students can discover for themselves how the concepts work.

I especially like the OBBL Architecture Blocks. You can build with different architectural shapes, but the blocks have gravity for an added challenge! Beyond that, you’ll find a balance activity, an age calculator (in hours, minutes, etc.), logic challenges, fractions, tesselations, polygons, place value, ‘really big numbers,’ story problems, crafts and much, much more.
