Challenger uses phonics, controlled vocabulary, and sequential skill development while building reading, comprehension, and writing skills. Books 1–4 emphasize learning to read, developing basic decoding, vocabulary, and writing skills.
Word analysis skills include phonics, word families, prefixes and suffixes
Reading comprehension skills include main idea and detail, making inferences, cause and effect, and literary interpretation
Controlled vocabulary is developed through fiction, nonfiction, and literary reading selections based on topics and themes that interest adults
Writing mechanics and composition skills are developed in each lesson, with more practice included in the writing books
In Book 1, students read original fiction and follow a group of adult characters. Each lesson begins with a phonics chart that reviews and reinforces basic decoding skills.
