Volcano maths quest: money

Quick answer

You can use maths to plan your money for a volcano adventure by counting coins, adding prices, and working out if you have enough to buy what you need.

Learning outcome

By the end of this page, you will be able to add up money amounts and decide if you have enough to buy items, just like a real volcano explorer!

• You can count different coins and notes to find the total amount
• You can add up prices of items to see how much they cost altogether
• You can compare your money with the cost of items to see if you can afford them
• You can solve simple problems about buying things with money

Why this matters

When you go on a volcano adventure, you need to know how much money to bring and how to spend it wisely. Whether you're buying lava-safe boots, snacks, or tickets to a volcano museum, you'll need to count your money and make sure you have enough. This helps you be a smart explorer and avoid running out of coins when you need them most!

How it works

First, you need to know the value of different coins and notes. Then, you can add up the prices of the things you want to buy. Finally, you compare your total money with the total cost to see if you have enough. Let's explore how this works with a volcano adventure!

Examples you can see

Imagine you are on a volcano adventure and need to buy supplies:

Example 1: Buying Snacks

You have 50p and want to buy a snack that costs 25p. How much change will you get?

• Start with 50p
• Take away 25p
• Change = 25p

Example 2: Buying Tickets

You want to buy 3 tickets for the volcano tour. Each ticket costs 15p. How much do you need altogether?

• 15p + 15p + 15p = 45p
• Or 3 × 15p = 45p

Example 3: Budgeting for a Trip

You have £2 and want to buy a lava-safe hat (75p) and some snacks (50p). How much will you spend?

• 75p + 50p = 125p
• 125p = £1.25

Volcano Explorer's Shopping Challenge

You are planning a trip to the volcano and need to buy supplies. Here's your mission:

4th time: You have 70p to spend. You see a lava-safe boot that costs 45p. How much money will you have left?

5th time: You want to buy 2 lava lollies that cost 10p each. How much will they cost altogether?

6th time: You have 80p and want to buy a volcano map (30p) and a snack (25p). How much will you spend?

7th time: You have £1 and want to buy 4 volcano stickers that cost 15p each. How much will they cost?

8th time: You have 95p and want to buy a lava-safe hat (60p) and a snack (25p). How much money will you have left?

Common mistakes

• Mistake: Adding up the wrong numbers when adding prices
• Why it happens: When adding prices, it's easy to make a mistake with the pence or pounds
• Fix: Always double-check your addition and write numbers clearly
• Mistake: Forgetting that 100p equals £1
• Why it happens: Some children don't fully understand the relationship between pence and pounds
• Fix: Practice counting in 100s to see how many pence make a pound
• Mistake: Not checking if you have enough money before buying
• Why it happens: Sometimes children buy things without thinking about the total cost
• Fix: Always add up your total before spending money
