Cows is part of the Let's Read collection of media enhanced books designed for children ages 5 to 7. These books were created to inspire beginning readers to become independent readers.

By the Third Grade,students are expected to instantly recognize the first 300 of these words. The Let's Read books combine these 300 sight words with vivid color photography and non-fiction content within a Kindergarten to Second Grade curriculum framework. Cows is an AV2 media enhanced book that gives readers access to embedded weblinks, audio and video clips, activities, and other features, such as matching word activities, slide shows, and quizzes.
