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. The exercises in Explode The Code Book 3 1/2 reinforce the sounds learned in Book 3. Exercises begin with long vowels with silent-e and progress to consonant and vowel digraphs. Students practice blending sounds to read and write one-syllable words that include digraphs and long vowel sounds. In addition, several review lessons are included. Grades 1-3.
