Learn to read, write and spell at home or at school, all while having fun! Blends Workbook activities progress week-by-week around Phase 4 of the Letters & Sounds systematic phonics program. This workbook supports children as they begin to learn the 44 letter sounds of the English language. The Blends Workbook has been designed for 5 year olds, and is the fourth of six workbooks that together form the Letters & Sounds Workbook program. As your child begins to sound out words in each activity, they will also develop their skills in reading and spelling, while having fun at the same time!
