This website is a community of people who make things. I googled it while trying to figure out the best way to make something for a class of mine. What i found is a reference place for how to make almost anything. With so much know how and creativity you could keep a class busy for weeks with just the things on the first page after searching something. There is sooo much you could do with this site.

First, it's a DIY webpage so if there's something your classroom could use, instead of buying it. You could make it and save some cash.

Second, there's tons of projects for things that kids would love; you could build cheap, quick, but highly personal rewards from the plans on the website. 

Third, you could find projects that kids could do or help with and make a teamwork activity out of it.

Fourth you could make something in class, teaching as you build. (So many possibilities)

Just search through, type in something like "for kids" or "for school" and you'll have plenty of possibilities that are always growing.
