Reading Horizons is a simple method for teaching reading. As a Reading Specialist and National Board Certified Teacher, I like Reading Horizons because it works! Students of all abilities respond to this method because of the unique coding system. It's also easy to differentiate instruction for the lowest reader to the most advanced reader in my class. I also like the higher order thinking and language development that is involved when students orally "Prove" a word. The support staff and the product will not disappoint!
