This is a terrific series for parents and children to read together, because it was specifically designed for that purpose. The books invite parents to read the left-handed pages of the book, which feature a more complex text and storyline. Then, children are encouraged to read the right-hand pages, which feature less complex text geared towards their reading level. The series offers both fiction and nonfiction options at every level, with full-color pages in each book. The fictional stories generally have colorful, cartoon-like illustrations while the nonfiction ones usually contain vivid color photographs of the featured topic. All the books in the series are fun and interesting to read. Each book measures 6.75” x 9”, 44 pgs, pb. ~ Rachel
