Explode the Code 4 2E

Explode the Code Book 4 (2nd Edition) guides students through advanced phonics concepts with systematic instruction in compound words, common word endings, and syllabication. This 94-page consumable workbook from Educator's Publishing Service introduces five syllable types—open, closed, Cle, silent-e, and digraph—while teaching students to decode and spell multisyllabic words. The program's Orton-Gillingham foundation provides multisensory learning through encoding, decoding, and writing exercises that build phonological awareness alongside practical reading skills.

Students work through lessons covering essential word endings (-ful, -ing, -est, -ed, -ness) and practice syllabication with 2- and 3-syllable words, developing the foundation needed for reading complex text. The 2nd edition features revised student directions for improved clarity and updated illustrations that help clarify key concepts. A review lesson and posttest allow students and teachers to assess mastery of the skills presented.

Designed for grades 1-3, this workbook fits into the proven Explode the Code sequence that builds from basic phonics to advanced reading skills. The consistent lesson format enables many students to work independently while the systematic approach ensures comprehensive coverage of essential phonics patterns needed for reading fluency.
