A web-based sticky note tool
PrimaryWall is a web-based sticky note tool designed for classroom use that allows students and teachers to work together in real-time. Each sticky has a title, a place to type the note itself, and another for the author. Everyone who goes to the same "wall" can add stickies.
Stickies can be repositioned easily for grouping and clustering. (It looks like it will work with iPads as well.) Great for brainstorming and anticipation guides
