About this resource

This affordable card pack gives families 12 ways to explore design thinking with ordinary materials. Challenges include a paper bridge, a steady tower, a shade structure, a paper chain, and a folded-paper ramp. Each card offers a clear goal, suggested materials, a safe test, and a prompt to record one change.

Younger learners can choose materials and notice what happens. Older learners can plan a fair comparison and explain which feature changed. An adult should select materials, supervise building and testing, and handle scissors or tools. No challenge requires a purchase. This is family enrichment, not an engineering assessment, standards certification, or promise of a particular outcome.
