shoot, on vacation now and left book at home. If I remember correctly she has a whole section on homework. So it should be covered there. She also has a full section on things that should be in 504's or IEPs (if I remember correctly).
Also, many schools now post homework on the internet (they all should!)
And something about getting his homework written down should be in his IEP. His manager should be very helpful with this
And this site has a number of good ideas
Hope this helps!
Oops..forgot to thank you. I didn't want you to think I haven't read the post...that always drives me crazy!
