I've been trying to help my son at spelling and got him a whiteboard for his room and it seems to help.
Something like this: http://www.designerallboards.com.au/whiteboards-melbourne/1200mm-x-1200mm-Commercial-Magnetic-Whiteboard

It does seemed to of helped with Maths and English when trying to commit to memory complex problems and would recommend that going over complex tasks that need to be embedded it helps.
Good idea. I have a little hand-held one about the size of a file folder that comes in handy when some quick graphics are needed.
