thankfully our DS10 teacher uses the "words your way" program... it has been AMAZING. they take a test to see where their spelling falls apart and then each week the list focuses on a 'rule' of spelling. he went up 5 levels in one year because the words werent just some seemingly random list. he really has made such great progress. he has an APD and w/ the clear rules for each week's words, it has made spelling quite 'easy' for him considering he went from spelling horribly (where you couldnt even GUESS what he was trying to spell) to now having great phonetic spelling even w/ words he is unsure of!
