One of the most effective approaches for spelling patterns is to start with small words, typically one-syllable words that merge vowels and consants -- ant, for example. The leading letter (the one that sounds strongest) should usually be the one rehearsed first, while the others are usually spelled around the leading letter. This method will expand to larger words as student fully learns the 500 key spelling patterns.
The hope is that teachers can take notes and utilize this strategy to help students with Dyslexia catch up to their peers and make the best grades!
