Browse lists of materials for each STARI unit. You can add items from this list to your cart. Suggested quantities are included in the descriptions for each book. We recommend purchasing extra copies for the teacher and to replace copies that are lost or damaged. Schools that have multiple STARI classes using the same units may choose to have multiple classes use one classroom set instead of purchasing one per student. In STARI, students are never expected to bring literature home with them in order to complete homework, so you can expect that books will remain in the classroom.
