Weekly Allowance maths mission

Quick answer

Weekly allowance maths mission is a fun way to practice multiplication by thinking about how much money you earn each week and how much you can buy with it.

Learning outcome

By the end of this page, you will understand how to use multiplication to work out how much money you have over several weeks, and how to plan your spending using multiplication.

• You can multiply numbers up to 12 by 1, 2, 5, 10, and 11
• You can work out how much money you earn in a month or a term
• You can use multiplication to decide how many items you can buy with your money
• You can think about how to save and spend your allowance wisely

Why this matters

Multiplication helps you understand how much money you have over time, and how to spend it wisely. When you get a weekly allowance, you can use multiplication to see how much money you'll have after a few weeks. You can also use it to work out how many things you can buy with your money. This is useful for real life, like shopping, saving up for a toy, or planning a party.

How it works

Multiplication is like adding the same number over and over again. For example, if you get £2 each week, and you want to know how much you'll have after 5 weeks, you can add 2 + 2 + 2 + 2 + 2, or multiply 2 × 5. The answer is 10. You'll have £10 after 5 weeks.

1. Start by knowing how much money you get each week
2. Decide how many weeks you want to count
3. Multiply the weekly amount by the number of weeks
4. Use the result to plan your spending or saving

Examples you can see

Let's look at some real examples to help you understand how this works.

Example 1: Weekly allowance

If you get £3 each week, how much will you have after 4 weeks?

• Week 1: £3
• Week 2: £3
• Week 3: £3
• Week 4: £3

You can add these up: 3 + 3 + 3 + 3 = 12

Or multiply: 3 × 4 = 12

You'll have £12 after 4 weeks.

Example 2: Buying items

If you have £10 and each pencil costs £2, how many pencils can you buy?

• Each pencil costs £2
• You have £10
• How many times does £2 go into £10?

You can think: 2 × 5 = 10

You can buy 5 pencils.

Example 3: Monthly savings

If you save £5 each week, how much will you have saved after 8 weeks?

• Week 1: £5
• Week 2: £5
• Week 3: £5
• Week 4: £5
• Week 5: £5
• Week 6: £5
• Week 7: £5
• Week 8: £5

You can add: 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 40

Or multiply: 5 × 8 = 40

You'll have saved £40 after 8 weeks.

Try it as a mini adventure

Imagine you are going on a Weekly Allowance Maths Mission!

You have a treasure map that shows how much money you earn each week. Your goal is to collect enough money to buy a special toy. But you must plan your spending wisely!

Adventure Step 1: Set your allowance

Decide how much money you get each week. For example, £3 per week.

Adventure Step 2: Choose your toy

Choose a toy you want to buy. Let's say it costs £15.

Adventure Step 3: Calculate how long you need to save

You have £3 each week. How many weeks will it take to save £15?

• Week 1: £3
• Week 2: £6
• Week 3: £9
• Week 4: £12
• Week 5: £15

It will take 5 weeks to save enough for the toy.

Adventure Step 4: Plan your spending

Once you have your money, you can buy small things too. For example, if you save £10, you could buy 2 stickers at £2 each and a pencil at £1.

• 2 stickers: 2 × £2 = £4
• 1 pencil: £1
• Total: £4 + £1 = £5

You'll have £5 left over.

Common mistakes

• Mistake: Adding the allowance instead of multiplying
  Why it happens: Children may not yet understand that multiplication is repeated addition.
  Fix: Use visual aids like counters or drawings to show how many groups there are and how many items are in each group.
• Mistake: Forgetting to include the first week
  Why it happens: Children might think they start saving in the second week.
  Fix: Remind them that the first week is the start of their saving journey.
• Mistake: Thinking that multiplying by 10 means adding a zero
  Why it happens: Children may confuse this with place value rules.
  Fix: Practice with real examples, like 10 × 3 = 30, showing 10 groups of 3 items.

Parent and carer guide

Helping your child with their weekly allowance maths mission is a great way to build real-life math skills.

• Start with what they know: Ask them how much money they get each week.
• Use real-life examples: Talk about how they could save up for something they want.
• Play the game: Create a simple game where they earn money for tasks and plan their spending.
• Ask questions: "How much will you have after 3 weeks?" or "Can you buy 5 stickers with your money?"
• Don't pressure: Make it fun and exploratory. Let them make mistakes and learn from them.

Remember, the goal is to build confidence in using multiplication for real-life situations. Keep it light and encouraging!
