Money - Four Operations - Presentation

The lesson on 'Four Operations' within the context of money introduces pupils to solving financial problems using addition, subtraction, multiplication, and division. Students are encouraged to collaborate with partners to create stories involving monetary calculations. For instance, the lesson explores scenarios such as Tia spending a quarter of her £48, requiring students to calculate her remaining balance using a bar model. Another example has Theresa spending two-thirds of her £39, again prompting students to determine what she has left. These activities help children visualise and understand the concept of fractions in monetary terms and to apply their knowledge of the four operations to real-life situations.

Further practical applications include calculating the cost of bowling and cinema trips for families at different times and days, showcasing how prices can vary. Students are tasked with using the appropriate operation to find the total cost for various group combinations. The lesson also covers discount scenarios, such as Zach purchasing clothes at half price, where students work out the savings made from the original cost. Additionally, they are faced with a decision-making problem where Zach must choose between a flat discount or a percentage reduction, encouraging them to compare which option offers greater savings. Independent work reinforces these concepts, with exercises that require clear documentation of calculations and reasoning. The lesson concludes with a discussion on how to effectively use bar models, partition money, and explore alternative problem-solving methods.
