Zeb Books recognizes that many children learn to read through phonics, and these books were such a success at her own school that Carol Zerboni was motivated to produce them into a series for children all over the world. is broken up into four volumes: · Volume 1 focuses on short vowel sound & sight words. · Volume 2 focuses on long vowel sounds & sight words. · Volume 3 focuses for blends and diagraphs, and · Volume 4 focuses on compound words & "R" controlled vowels. The books begin on an easy level and progress in difficulty as the child masters new phonetic skills with each volume. The books work best with an individual reading approach; one child to one teacher. We hope you'll enjoy the books and the ride!
