Each book is assigned a color coded level. Level 1 (preK-1st grade) is for beginning readers. Level 2 (1st-3rd grade) is reading with help. Level 3 (2nd-4th grade) is for reading alone. Level 4 and the chapter books are for 3rd grade+, and are for advanced readers. These readers contain actual stories that children will enjoy, rather than simple words strung together. They are books that children can, as they claim, read, and that they will read over and over.
