🔄 Revision Plan & Prototype 2

Students review feedback and circle one user challenge to fix (e.g., unclear rules, problems too easy, too slow). They draw a simple before/after sketch in their iteration log and explain why the change helps the user solve within 20 more quickly. Students then build Prototype 2 with sturdier materials (thicker board, rewritten cards, clearer rule card) and retest briefly with a new partner.
