MindMeister is a Web 2.0 tool that allows its users to create mindmaps using text, images or links. These mindmaps function like a web, with each idea branching out to several concepts included within it.

Teachers can assign the students to create mindmaps as projects, or use mindmaps as notes for students. This would help break down learning barriers for students who have difficulty organizing their ideas, as well as students who struggle with reading or need more visual stimuli to learn best.

Mindmeister has no age requirements listed in it's terms and conditions.
