Workbook 4 follows the same format as the preceding workbooks. It introduces consonant digraphs and words with a vowel followed by the letter r. Once students have completed Workbook 4, they should be able to read, write, and spell simple words. Skills addressed include r-controlled vowels; -le; -ng, -nk; consonant digraphs (sh, ch, wh, th); initial consonant blends; final consonant blends; vowel digraphs (ie, oe, ee, oa, ai, ea, ee); short vowel sounds; silent-e; sight words.
