Hi S.,
My son has ADHD and an IEP in place, he is in 6th grade, He is only required to learn and test on 5 out of 20 spelling words, One thing I've learned about my son is if he gets overwhelmed, life is to big and he cant even do the things he normally does, When I make his learning simple and small, he takes off like fire, (Its taken a while to learn that, I didn�t understand his AHAD) I do make fun stories, rhyming, etc. for spelling. Just this last year, however, I've quit making "Spelling Correctly" a priority, I relaxed and accepted my sons limitations, I follow my intuition more and worry about his grade less, he has a disability, I need to respect that, so I decided if I can just teach him how to learn to spell, look words up in the Dictionary, spell check on computers, grammar, A before E except after C, etc. Then just study his spelling words the best we can, (he prefers at bed time and once more the morning of the test just a quick review) we are both much happier and he feels good about him self, he doesn�t feel frustrated or stupid.
Good luck to you, I know it's so hard and heart breaking when they struggle in school.
I love all the advice I read on your topic. Thanks Everyone.
