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. This is the teacher guide to Mr. Popper's Penguins, Tales from Beatrix Potter, The Courage of Sarah Noble, and Little House in the Big Woods.
