Tips
To deepen the learning, have the student create a detailed profit‑tracking worksheet that includes fixed and variable costs, then graph monthly earnings to visualize trends. Next, set up a mini‑workshop where they teach a sibling or friend how to perform one basic repair, reinforcing mastery through teaching. Invite them to interview a local small‑business owner about pricing strategies and incorporate those insights into a revised marketing flyer. Finally, organize a field trip to a hardware store or a community garage sale to observe real‑world pricing, inventory, and customer interaction in action.
