The topic of money in 11-plus Mathematics focuses on essential skills needed for handling financial calculations. This includes adding and subtracting money, calculating change, and solving multi-step money problems. Mastery of these skills is crucial for everyday life and is a key component of the KS2 curriculum.
When adding or subtracting amounts of money, it is important to align the decimal points to ensure accuracy. For example:
Problem: If you have £12.50 and you spend £4.75, how much money do you have left?

You have £7.75 left.
Calculating change is a common task when making purchases. To find the change, subtract the total cost from the amount given to the cashier.
Problem: You buy a toy for £8.20 and pay with a £10 note. How much change should you receive?
Solution:
Your change is £1.80.
Multi-step problems require careful reading and often involve several calculations. It is important to break down the problem into manageable steps.
Problem: You buy 3 notebooks at £2.50 each and a pen for £1.20. How much do you spend in total?
Solution:
You spend a total of £8.70.
Understanding profit and loss is essential for making informed financial decisions. Profit is the amount earned after expenses are deducted, while loss occurs when expenses exceed earnings.
Problem: If you buy a book for £5 and sell it for £8, what is your profit?
Solution:
Your profit is £3.
Discounts are often given during sales, and calculating the sale price is important for budgeting. To find the sale price, subtract the discount from the original price.
Problem: A jacket costs £40 and is on sale for 25% off. What is the sale price?
Solution:
The sale price of the jacket is £30.
Managing a budget involves tracking income and expenses to ensure that spending does not exceed available funds. Understanding how to read and calculate bills is also essential.
Problem: If your monthly budget is £200 and you have spent £150, how much money do you have left for the month?
Solution:
You have £50 left in your budget.
By mastering these concepts, students will be well-prepared for the money-related questions they may encounter in the 11-plus examination.
