Explode The Code provides a sequential, systematic approach to phonics in which students blend sounds to build vocabulary and read words, phrases, sentences, and stories. Frequent review of previously learned concepts helps increase retention. Each workbook in this series contains exercises that incorporate reading, writing, matching and copying. The consistent format of the books helps facilitate independent work. Explode The Code Book 8 introduces students to more complex morphemic units including suffixes and irregular endings. Students combine word parts to create multisyllabic words and increase their vocabulary by learning the meanings of common suffixes and endings. Several review lessons are included along with a posttest. Grades 2-4.
