Book Adventure is a FREE reading motivation program for children in grades K-8. Children create their own book lists from over 7,000 recommended titles, take multiple choice quizzes on the books they've read, and earn points and prizes for their literary successes. Book Adventure was created by and is maintained by Sylvan Learning. Developed and initially funded by the Sylvan Learning Centers and Sylvan Learning Foundation in April of 1999, Book Adventure is designed to encourage students in grades K-8 to read more often, for longer periods of time, with greater understanding.
