Level 1: BEGINNING READING Short sentences, familiar words, and simple concepts for children eager to read on their own. This level is just right for readers who are beginning to sound out words and sentences. Books on this level, Amelia Bedelia, are written with simple sentences using familiar words. The vocabulary is just challenging enough to stay interesting. Level 2: READING WITH HELP Engaging stories, longer sentences, and language play for developing readers who still need some help. Level 2 is for readers who are increasingly confident, but still need some help. Books at this level, Amelia Bedelia titles include more complex story lines, longer sentences, and more challenging words. - from Amzon
