Phonics and Reading Workbook 1 The Horizons Phonics and Reading 1 program consists of 2 student workbooks that teach phonetic concepts, and 2 readers that allow students to practice what they have learned. For example, students memorize phonics and spelling rules to recognize the relationship between letters and sounds, and this will enable them to decode new words. The Teacher's Guide includes lesson instructions as well as tips and teaching strategies. This item is the first workbook in the Horizons 1 program."
