Workbook for Grade 1 Reading 2nd Edition (1985-1986). This edition is not compatible with the current 3rd edition (2016).
These units continue to teach and review letter sounds and their combinations, give practice with phonetic words, and provide seat work in phonics.
Each lesson has a world list where the sounds are applied to various combinations. This helps them to gain speed in the use of phonics. It emphases both single letter sounds as well and multi-letter sounds.
The teacher's manual contains the answers.
