Children who are asked to read slightly above their comfort level will develop into superior readers. Reading requires an active, discriminating mind that is challenged to think, compare, and contrast. Our literature study guides train students to become active readers. They focus on vocabulary, spelling, comprehension, and composition skills. Mr. Popper's Penguins by Richard and Florence Atwater is an unforgettable tale inviting readers to imagine, dream, and believe that anything is possible.
