In second grade, readers are refining their comprehension skills, beginning to read early chapter books and analyzing theme and points of view of a story. Lessons are taught by colorful animated characters that explain and interact with the reader. Reading and writing exercises apply the skills that are taught throughout the novels. It is extremely important to expose children early to both "window" and "mirror" books. These are books in which they can see themselves, and books in which they can learn about others. This is the best way to create engaged readers and support social and emotional growth.
