That’s entirely up to you and your students. The suggested schedules in the Young Explorer notebooking journals cover a full year and assume that you will do science twice a week for 28 weeks. Each textbook includes access to exclusive Book Extras, featuring supplemental materials such as links to videos, interactive activities, and other resources to further extend the lessons. 

Some students jump right in and immerse themselves in a subject, while other students enjoy a more deliberate pace. Each title in the series is designed for maximum flexibility to fit your family's unique schedule and needs.
