Our family is using All About Spelling. I have a 3rd grader and a 13yr old dyslexic which use this program. My dyslexic son loved this program from the beginning. It's fun and easy for him to learn it. Can't beat the fun part. Here is a whole article about dyslexia.
This is what we use for spelling. So what I write about our spelling curriculum is from experience. We are also an affiliate which helps us continue in our wonderful choice of spelling programs. I'm sure those two free e-books will not be free for long so grab them while you can.
