Hey! I'm 25 and still have ADHD.
People with ADHD learn differently than normal people.
We don't like doing something if we think it is useless. In other words, if your child is told to learn something without the reasons of why it's applicable to life, then he won't do it.
My parents worked extra hard with me in grammar school because of my ADHD. The problem was once I matured into highschool and college, I didn't have my parents as a crutch. I had to do things on my own. And that didn't work out so well.
I feel teachers teach in a style that is learnable to normal children, but not learnable to kids with ADHD. I only can learn something if I feel passionate about it.
It's no wonder that I am doing more learning now that I've graduated college than I ever have in my entire life. Why? Because I'm falling into subjects that are valuable to ME.
I like learning how to be creative, and I love things that have to do with human behavior. I find people with ADHD have an entrepreneurial spirit that normal people seem to lack.
We are good at fixing leaks (metaphorically), we are good at creating things, we are good at managing and delegating. We know how to hustle (when we know it's valuable). We are very charismatic (in our own way).
I find I learn best visually and sonically, just a smidge more effective than text. Though, text is valuable if it is INTERESTING!
How is it that in the past two days, I have watched over 8 hours of video on how to market your brand? In the past month, I have watched more than 30 hours of video on human behavior? In the past 5 years, I have mastered the art of human interaction by reading endless psychological and human behavior books. I have studied facial expressions and emotional intelligence by Dr. Paul Ekman and Daniel Goleman like crazy in the past seven months.
What I'm trying to say, is when I think something is beneficial to my life, I jump on it and devour it whole. However, if I think something is a waste of time, I will do everything in my power to avoid it.
Take the time to teach your child the benefits of the work he is doing. A person with ADHD thinks, "Why should I be studying, doing homework, and taking tests for no reason? All of this stuff is boring and not applicable to my life. I'd rather sit and do nothing than do this work."
Teach him and let him experience why these things are interesting.
If it is math, bring him to the store and tell him to pay the cashier, while managing to receive no coins back, only bills.
If it is social studies, bring him to different parts of the world (even the country), and show him different cultures.
If it is english, show him the excitement YOU receive out of reading books, and writing letters. Have him write a letter to a friend or relative across the country. Let him understand the benefit of learning the english language.
You have to make him understand why these things are beneficial to his life. Make him WANT to do these things, not just resign to them.
You need a teacher that makes this stuff INTERESTING. That's why Bill Nye was so great. That's why Mythbusters is huge. He needs Bill Nye as his teacher.
What do I recommend? Join the PTA board. Make friends with all of the teachers. Find the one that is the most charismatic, and push to get your kid in THAT TEACHER'S class. We learn best when the person teaching us is exciting. Why? Because if someone teaching it is excited about the subject, so are we. Because it must be valuable.
Find the teacher that teaches students in a different way. It sucks to have ADHD and have to live in a world where people learn differently than you do.
