How to Teach "Highly Distractable"/ADD Kids

I just found a website by a homeschool mom with an ADD son, and she has some interesting tips: http://www.westfieldacademy.org/adhd/. I also found some facts that surprised me about kids with ADD - stuff that definitely describes Isaac. I'm not sure if this is encouraging or discouraging, but it's a relief to know that other kids have these problems:

(These were under the heading, "Educational recommendations for kids with ADD"):

1. Encourage individualized activities that are mildly competitive or noncompetitive such as bowling, walking, swimming, jogging, biking, karate. (Note: Children with ADD may do less well than their peers in team sports.) Isaac definitely has problems with team sports - interesting that ADD could be part of the reason.
2. Allow children with ADD to play with younger children if that is where they fit in. Many children with ADD have more in common with younger children than with their age-peers. They can still develop valuable social skills from interaction with younger children. This is so true of Isaac - he always gravitates toward younger kids when given the option to choose his playmates. It doesn't seem as disturbing to me now that it might be related to ADD.

Two more days until his appointment with the doctor. I'm feeling more confident now that getting him back on his medicine will help. It will be a good week.
