Tips

To deepen the learning, have the child create a simple budget worksheet where they plan a mini‑sale: set a goal for total sales, calculate the number of items needed, and record actual results. Next, guide them to write a short “sale flyer” that includes persuasive language and a clear call‑to‑action, then display it at home for practice. Organize a pretend “market” day at home where family members role‑play as buyers and sellers, incorporating price negotiation and change‑making to solidify money concepts. Finally, reflect together on what worked well and what could improve next time, encouraging critical thinking and goal‑setting for future community projects.
