Hi Kelly,
I just found this Silver Moon spelling and I want to try it out. I am excited about it. I tutor reading online. Usually I have students that are struggling to become readers but occasionally I have someone inquire about tutoring for an older child who is a reader but struggles with spelling and comprehension. I think this would be just the thing for those students. I used Barton with my own children and I am guessing you were also a Barton person before becoming the author of Silver Moon Spelling rules. Also I see that rules about suffixes are coming next and I am anxious to try this out.
