Sequential Spelling is based on the classic Orton-Gillingham approach of multi-sensory instruction. Rather than teaching lists of thematic words, Sequential Spelling teaches spelling word families (e.g. consonant + "at" family = bat, rat, brat) enabling the child to learn spelling inductively, the exact same way they learned to speak and to walk. This form of instruction helps struggling students to succeed and challenges excelling students to achieve!
Regardless of age or grade, your child will start with Sequential Spelling Book 1 and move through the books within the series.
