Study guides and resources for teaching proper etiquette online. The site actually offers much more though. There are study guides and help for almost every topic you can think of.
Really cool site where you can look at children's art from around the world. If you are an art educator you can add your students work as well which I am sure the kids really enjoy.
This page has a lot of games and free coloring book pages for kids. I found sometimes it's nice to have things like this on hand for kids that may finish a project a little earlier than some of the other students.
Rednose Studios has done several magazine covers, among other things. They have a blog and an online store. Their art is quirky and cute but has a deeper meaning than the first glance would show.
