Tips

To deepen Aiden's learning, have him conduct a price‑research project where he compares his item prices with three other online sellers and creates a visual chart of the data. Host a mock negotiation session with a friend or family member where Aiden practices crafting counter‑offers and explaining his price rationale. Introduce a simple spreadsheet activity that tracks each item's cost, listing price, offers received, and final profit, then discuss the profit margin percentages. Finally, assign a reflective journal entry where Aiden writes about how he felt when declining offers, encouraging emotional awareness and decision‑making reflection.
