Did you know that a koala sleeps for 20 hours each day? Koalas only eat the leaves from one type of tree. Find out these and more exciting facts in I Am a Koala. Koala 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. Educator and reading expert Dr. Edward Fry created a list of 1,000 instant sight words. These 1,000 sight words must be learned by students in elementary grades. 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 nonfiction content within a kindergarten to second grade curriculum framework.
