Tips
To deepen Luke's learning, have him keep a weekly snack‑budget journal where he logs each purchase, price, and remaining balance. Next, organize a price‑comparison field trip to two different stores, prompting him to calculate unit costs and discuss value. Incorporate a short research project on euro currency history and current exchange rates to link math with global awareness. Finally, challenge him to design a mock self‑checkout screen on paper or a simple app, explaining each button’s purpose and testing it with a sibling or friend.
