Breaking the Sound Barrier is easy to read. It's a step-by-step instructional manual for parents and caregivers who wish to promote pre-literacy skills in pre- and beginning readers and help establish and consolidate reading, writing, and spelling proficiency in early readers. Furthermore, Breaking the Sound Barrier is an invaluable resource for established readers who do not have an understanding of the relationship between the letter and sound principle of phonemic awareness, usually illustrated by poorer spelling competency.
