The Mc-Graw Hill First Grade Wonders CD offers support materials to enhance your program. Each unit lessons has a seven page activity packet (30), a guided reader (41) for independent practice of high frequency words and/or phonics skills, and matching big books. The phonics focus is covered through 17 literacy center activities and 33 word family sets. All activities address the high frequency word focus and phonics skill outlined in the publisher's matrix. I have purposely kept the price of this CD at a low rate so that teacher can purchase it. I have added shipping and handling into the cost.
