Launch, build, and extend

Based on years of research that demonstrate the importance of teacher-student interactions, immediate and regular access to the best literature available, and the need for social-emotional development instruction, Big Day for PreK offers teachers a thematic and integrated approach to guiding our youngest learners. Organized around eight themes that grow in scope as children become more aware of their surroundings, the program introduces children to math, literacy, science, and the arts in a way that feels like play and inspires joyful engagement.

Big Day was designed based on proven early childhood principles.

Offering the best fiction and nonfiction available ensures our youngest readers become lifelong lovers of literature.
