A 90-minute experiential PD session for educators of PK to 3rd grade learners (early childhood and lower elementary). Each educator builds their own Blendie, then unpacks symmetry, balance, optical color mixing, and the engineering design process, plus a coaching playbook for hands-on STEAM facilitation. Educators leave with a class pack (25) of Blendies for their own classroom, the Blendies slide deck, a Quick Start Guide, three iteration prompts they can reuse with any maker activity, and a clear plan for running their first session.
