Money - Subtract Money - Presentation

The presentation focuses on the subtraction of money, a key mathematical skill for Year 6 students. The lesson revisits various subtraction methods that can be applied when dealing with monetary values. Students are encouraged to discuss and share the subtraction techniques they are familiar with, which sets the stage for the main activities. The initial exercises involve straightforward subtraction problems where students calculate the remaining amount of money after a certain sum has been given away. For instance, Tia starts with £4 and 50p and after giving £2 and 10p to a friend, she is left with £2 and 40p. Similarly, Malachi has £8 and 90p, and after giving £5 and 55p to a friend, he retains £3 and 35p.

Subsequent activities delve into more complex scenarios involving comparisons and discounts. One problem asks how much more money Rosie has compared to Malachi, with Rosie having £2 and Malachi having £1 and 64p. The solution involves finding the difference between the two amounts, which is 36p. Another activity presents a real-life context where a T-shirt's price is reduced from £6 and 40p to £4 and 70p in a sale, and students must calculate the discount, which is £1 and 70p. Additionally, reasoning exercises challenge students to apply their understanding of multiplication and subtraction to find out how much more money one person has compared to another. For example, if Malachi has three times as much money as Zach, and Rosie has twice as much money as Malachi, students must calculate the respective differences. The lesson concludes with independent work where students can choose their preferred method to solve subtraction problems, be it partitioning, using a number line, or another strategy, thereby reinforcing their ability to manage and calculate monetary values.
