  • ✓Change-making and money handling practice
  • ✓Earnings tracking and profit calculation

What they are actually learning.

Your child runs an actual garage sale: prices the stock, handles the money, negotiates with customers and works out at the end whether they made anything. Profit stops being a definition when it is their own float and their own takings.

  • Pricing & Sales: Setting prices against condition, value and what the thing would really sell for, then negotiating
  • Number Sense: Totalling sales, calculating change under pressure, and computing profit against cost
Why it matters

When maths lives in real money, real measurements, and real decisions, it stops being a worksheet and becomes a tool. A kid who uses it to get something they actually want remembers it for life, and they did it with you. That is the moment "I taught my kid something real" starts to feel possible.
