Homeschooling the Challenging Child by Christine Field has been very helpful to me. It has lots of website addresses in it including one for chore charts for children with ADHD. This is a great book for people who really struggle with homeschooling or with kids with special needs. I even found sites in here for kids with math issues and I shared them with a coworker who struggles with math. He is around 20 years old and he says they've been very helpful to him! (this is a guy who failed basic math last year in college!)
Sorry, I'm rambling again..
