The We Thinkers! series (formerly named The Incredible Flexible You) is a Social Thinking educational series that combines a social learning framework with music and dramatic play activities for early learners (ages 4-7).

We Thinkers! Play GPS is a book that introduces several tools designed to help you understand children’s different levels of play, observe children’s play behaviour across varied contexts, use scoring sheets to determine play level, and then select play activities for that level.
