Tips
Extend the garage‑sale experience by turning it into a mini‑enterprise project. Have the child draft a short business plan that includes a budget sheet, a marketing flyer, and a target‑customer description. Next, set up a “stock‑room” where items are sorted by category, then conduct a simple inventory audit using a spreadsheet to track quantities, prices, and sales. Finally, hold a reflective debrief where the learner analyzes profit margins, discusses what marketing strategies worked best, and writes a brief report on how the experience connects to real‑world commerce and community sharing.
