What a great idea.....how old is your DS? I take it you can only do this for their homework though and not class done items? My DS6 as the WORST time writing in the spots on his first grade worksheets (and the fact that they are BORING and way below his level doesn't exactly help) and I keep seeing his teacher mark through them with red pen everywhere because after 2 weeks she doesn't understand what his reversals looks like - so she is marking him wrong for things that are actually correct but are backwards. This would be SO cool to be able to do in the classroom for him...how do you guys you use?>
