Wow, there is some good stuff for sub-IEP (home and informal) intervention for our minor tracking and handwriting issues. In particular, I can't believe we hadn't thought of:
"Provide a model - upper case and lower case letters of the alphabet – highlighted start dots for visual cues for proper letter formation. "
It's pretty obvious DS sometimes can't get the right forms straight in his head let alone get it to paper. Also color coding, highlighting instructions, constrast reduction, and visual windows all sound very helpful.
