Look past the simple appearance and you can find a great geometry tool.

My Take

This has the potential to be an absolutely wonderful tool. It is not there yet. The website is an interactive geometry text book. Originally designed for high school, it is easily used in lower grades to introduce a wide variety of topics. You have to be careful to avoid the ads that look like they are part of the site. There can be a lot of them. I also got one about how to improve your abs. While possibly helpful in its own way, not helpful during a classroom introduction on angles. The great part is that for a topic, you will get an interactive model, key vocabulary with definitions, demonstrations, possible extension ideas, and related topics. The interactive models, in my opinion, are the biggest asset of this website. They will give students visual models of the topics that they can move around and see how the vocabulary is related. For example, when introducing angles, the model lets you move around the angle and will give you the exact measurement as well as the type of angle (acute, obtuse, right...) as you move it. If they can get rid of the ads, or make them more appropriate, this could be a wonderful teaching tool that would be available to the students anywhere that they can get online.
