Level 1 provides the most support through repetition of high-frequency words, light text, predictable sentence patterns, and strong visual support.
Level 2 offers early readers a bit more challenge through varied simple sentences, increased text load, and less repetition of high frequency words.
Level 3 advances early-fluent readers toward fluency through increased text and concept load, less reliance on visuals, longer sentences, and more literary language.
Level 4 builds reading stamina by providing more text per page, increased use of punctuation, greater variation in sentence patterns, and increasingly challenging vocabulary.
Level 5 encourages children to move from “learning to read” to “reading to learn” by providing even more text, varied writing styles, and less familiar topics.
