A webiste that introduce musical concepts to kids in a fun way. More appropriate for grades 3-6 (good reading skills combined with computer knowledge) than younger. Might be a bit 'kiddy' for older kids, but I enjoyed it. It has changed a bit since they firsts introduced it in that there are a few more activities.

This is the homepage for my National association. Although it is mostly directed toward educators, there are articles and links in the website for advocacy.

Another good music theory website. Has animated lessons that help keep student interest. Good for middle school kids and up.

This is a good site to help kids learn basic music theory. The site has been updated since I started using it, and offers apps for mobile phones.

A great resource for creating, modifying or "stealing" rubric for just about any subject. I have used this for a number of year. You can create and save rubrics to the site and share them.
