DE Tools of the Trade is touting Classtools.net and Arcademic Skill Builders today. Both are probably known to most, but are worth checking out if they are new to you. Arcademic is particularly good for Elementary students and shows how good educational games can be. My students love it!

Head over to MakeUseOf to check out DropMind, an online and offline mind mapping tool. Educators with an edu address get a free premium account for a year!

Hot on the heels of ZuiTube is Kideos, (see what they did there?), another kid friendly YouTube alternative. It seems aimed very much at a younger audience, so good for Elementary students. iLearn has a full review. Also at iLearn today is SignApp, where you can create online sign up sheets.
