The Noteboard is a $10, foldable pocket whiteboard. It could be great for students and teachers to use in school. Pack it up in your bag and take it with you. Students can use it in class for projects, teachers can use it for different things and pack it away when not needed, and it would be great for conference presenters to take with us to our sessions. It would be great for students to use instead of paper for doing certain practice and projects. They could even use their smartphones to take a picture of their work before erasing and using it as a digital record of their work.
It is dual sided and foldable. Unfolded it is 35" x 5" and folds down to 5" x 3".
For $10, you get the Noteboard, a band to keep it folded, and a black whiteboard marker.
