Lesson Structure

Starter (10 minutes) — Money Puzzle Challenge

• Activity: Present a money puzzle on the whiteboard.
  Puzzle example: “If you buy 3 chocolate bars costing €1.75 each, how much do you pay?”
• Lower Order Question: What is the cost of one chocolate bar? (Recall)
• Higher Order Question: How would the total cost change if you bought 5 bars instead of 3? Explain your thinking. (Application/Analysis)
• Students discuss with a partner, then share answers with the class to engage communication skills.
• Purpose: Activate prior knowledge and introduce multiplication of money in a real context.

---

Development (25 minutes) — Practice with Book Questions & Worksheet

• Book Questions (15 mins): Use tailored questions from the class maths book focusing on multiplying and dividing money.
  • Lower Order Question: Multiply €4.50 by 3. What is the total?
  • Higher Order Question: A toy costs €12.60. If you divide this money between 4 friends equally, how much does each friend get? Show your working.
• Worksheet (10 mins): Students complete a differentiated worksheet combining:
  • Multiplying money amounts by whole numbers
  • Dividing money amounts into equal parts
  • Word problems requiring reasoning about costs and change
• Teacher circulates to support, encourage use of correct vocabulary, and challenge deeper thinking.

Conclusion (10 minutes) — Money Maths Game & Reflection

• Game: “Shopkeeper’s Challenge” — Students work in pairs with play money, alternating roles as customer and shopkeeper. They must calculate totals and change using multiplication/division in real-time.
• Lower Order Question: If a customer buys 2 items costing €3.50 each, how much do they pay?
• Higher Order Question: If a customer pays with €20 and the total is €13.80, how much change should they receive? What strategy can you use to calculate this quickly?
• Reflection: Students share one new term they learned and explain one thing they found tricky or enjoyable about the lesson.
• Teacher provides feedback and addresses misconceptions.

---

Assessment and Differentiation

• Observe student responses during partner and group discussions to assess understanding.
• Use worksheet answers to gauge individual mastery (higher and lower order question sets).
• Provide extension tasks for faster learners involving multi-step problems or budgeting scenarios.
• Support students needing extra help with visual representations and manipulatives (coins, play money).

---

Materials Required

• Class maths books with money exercises
• Printed worksheets
• Play money (coins and bills) for the game
• Whiteboard and markers

---

Teacher Tips

• Encourage use of euro notation (€) consistently, reinforcing currency literacy.
• Promote mental maths strategies, such as doubling or halving, to build fluency.
• Use real-life scenarios like shopping or budgeting to make problems relatable.
• Foster a collaborative classroom environment where students explain their reasoning aloud.
