Why this matters

Maths in pocket money helps you make smart choices. When you learn to compare prices, you can get more treats, toys, or games for the same amount of money. It's like being a detective, finding the best deal. This skill helps you in real life when shopping, splitting treats with friends, or saving up for something special. Understanding value also helps you plan your money better, so you don’t run out before you’ve had enough fun!

How it works

To find the best value when spending pocket money, you need to:
  1. Look at the price of something
  2. Check how many items you get for that price
  3. Work out how much each item costs
  4. Compare the cost per item with other options
This is like sharing a pizza equally among friends – you want to know how much each person gets. In maths terms, you are dividing the total cost by the number of items.

Examples you can see

Let’s imagine you have £2 to spend on stickers. You see two packs:
  • One pack has 4 stickers for £1
  • Another pack has 8 stickers for £2
To work out which is better value:
  1. First pack: £1 for 4 stickers → £1 ÷ 4 = 25p per sticker
  2. Second pack: £2 for 8 stickers → £2 ÷ 8 = 25p per sticker
Both packs cost the same per sticker. But what if the second pack was £1.50 instead of £2?
  • First pack: 25p per sticker
  • Second pack: £1.50 ÷ 8 = 18.75p per sticker
The second pack gives you better value because each sticker costs less.

Try it as a mini adventure

Adventure: The Pocket Money Shop You are a shop owner and have £10 to spend on sweets. You can buy:
  • 20 chocolate buttons for £2
  • 15 lollipops for £3
  • 30 jelly beans for £5
Your job is to work out which sweets give the best value for your £10. How many of each can you buy? What is the cost per sweet?
  1. Chocolate buttons: £2 ÷ 20 = 10p each
  2. Lollipops: £3 ÷ 15 = 20p each
  3. Jelly beans: £5 ÷ 30 = 16.67p each
So, chocolate buttons give you the best value. You can buy 20 buttons for £2, and with £10, you can buy 100 buttons!

Common mistakes

  • Mistake: Thinking the most expensive pack is always best value.
    Why it happens: Children might think more money = better deal.
    Fix: Always work out the cost per item, not just the total price.
  • Mistake: Adding prices instead of dividing to find cost per item.
    Why it happens: Confusing the steps in the process.
    Fix: Remember: to find value, divide the total cost by the number of items.
  • Mistake: Not checking if the numbers are fair.
    Why it happens: Not paying attention to what is being compared.
    Fix: Make sure you are comparing the same type of items – like comparing stickers to stickers, not stickers to toys.

Parent and carer guide

Parents, you can help your child by:
  • Using real-life shopping situations to practice comparing prices
  • Asking questions like: “Which is cheaper?” or “How much would one item cost?”
  • Letting your child use a calculator to check their answers
  • Encouraging them to explain their thinking
  • Using pocket money as a real-life maths tool
What to say: “You have £5 to spend. Which pack of crayons gives you more for your money?” What not to worry about: If your child makes a mistake, it’s a chance to learn. Ask them to explain their thinking, then guide them to the right method.
