Ask Natural Math and Naturalmath.com

Natural Math is a web mathematics community for math teachers and students founded by Dr. Maria Droujkova.  Despite being in is beta state, it’s one of finest math community website I’ve seen so far. It has a variety of features: a blog, a forum, a group interest and many more. Some of its notable projects are Math 2.0 Group Interest, Math Lexicon and Special Snowflake.

The most current addition to Natural Math, which is one of my favorites, is the Ask Natural Math page, where community members can ask, answer » Read more

Investigating Polyhedrons with Poly

Poly is a program for investigating polyhedral shapes. Poly can display polyhedral shapes in three main ways:

  • as a three-dimensional image,
  • as a flattened, two-dimensional net, and
  • as a topological embedding in the plane

The three-dimensional images may be interactively rotated and folded/unfolded. Physical models may be produced by printing out the flattened two-dimensional net, cutting around its perimeter, folding along the edges, and finally taping together neighboring faces.

Using Poly is fairly intuitive, so there is no need to post a tutorial about it. You can download Poly here.

Note: The text above was copied from the Poly readme file.

Complete List of Math Teachers at Play Carnivals

Let’s Play Math is an amazing blog hosted by Denise (I can’t find her last name). It is a haven of mathematical ideas and resources, both in teaching and learning school mathematics. Let’s Play Math is also the host (together with some other bloggers) of a  popular K-12 Math Blog Carnival on the internet, The Math Teachers at Play Blog Carnival.

Lately, I want to read the Math Teachers at Play Carnival, but I had a hard time looking for previous posts. To help myself and other readers, I have written the complete list of the carnivals linking to each issue.

I also started submitting my articles since Math Carnival #23, and several of my articles were accepted. I hope my list will help you find good reading materials.
