Research shows that the “just-right” level of book is essential for building students’ reading abilities and motivating students to read more books. That's why leveled books (and their interactive versions on CD-ROM) are at the core of the WiggleWorks program.

The 84 WiggleWorks trade books are a rich collection that introduces children to a range of genres, such as realistic fiction, nonfiction, and folktales. Equally important, the books in WiggleWorks help children discover the joy of reading with appealing characters and delightful pictures by some of their favorite authors and illustrators, including Norman Bridwell,
Eve Bunting, Pat Cummings, Alma Flor Ada, and Virginia Kroll.

The trade books are leveled in four stages, A, B, C, and D, which move students from beginning reading to independent reading. Within each stage, there are three graduated levels of books to meet the needs of every student. Working with the appropriately leveled books and corresponding CD-ROMs, students are well-equipped to build on their essential reading skills—phonemic awareness, phonics, fluency, vocabulary, and comprehension.



Stage A:
WiggleWorks books in Stage A deal with familiar experiences and concepts and provide strong art support. The text uses repetitive sentence patterns, language that is natural to children's speech, and oftentimes rhyme.

Stage D:
WiggleWorks books in Stage D may be longer and more complex, although most concepts are familiar to children. There is a variety of genres, including realistic fiction, animal fantasy, traditional tales, plays, nonfiction, biography, and poetry. The illustrations contribute to the text and add meaning to the story, but are not necessary for the child to understand the book.
