I've just seen a new white board lesson plan kit that is still in development at OptiMA. The kits, geared toward the classroom contain a dry erase magnet that looks to be about 2' x 3' as well as a set of dry erase lapboards and full sets of markers and microfiber erasers.
The unique thing about the kits is that each dry erase board is printed with beautiful full color graphics. The kit I saw had full color United States Maps on them; I can see these being extremely useful in interactive geography lessons.
The magnetic map will stick to a magnetic receptive whiteboard, chalkboard or any other metal surface and the 9x12" lap boards are perfect for students to write on and demonstrate their knowledge to the classroom without having to leave their desks.
There is no exact launch date for these kits yet but I'm told that they will be available soon and be more than ready to ship for next school year.
UPDATE: OptiMA has created a series of boards for students ranging from younger children to college aged kids. The series will include a kit based on the currency lap boards, a kit with X/Y axis grids and the polar coordinate grids.
