Super Mario Maker maths: coins and percentages

Use age-appropriate, adult-approved play examples to track collected coins, total coins and completion rates.

Quick answer

You can use Super Mario Maker to learn about coins and percentages by collecting coins, counting them, and working out what percentage of coins you've collected.

Learning outcome

By the end of this page, you will be able to count coins in a game and work out what percentage of coins you've collected. Success signs:

You can count how many coins you've collected in a level
You can work out what percentage of coins you've collected
You can compare how many coins you've collected to how many there are
You can explain how to find a percentage

Why this matters

Learning about coins and percentages in games helps you understand how many you've collected and how close you are to getting all of them. This is useful for games, school, and everyday life. For example, if you're trying to collect all the coins in a game, you can work out how close you are to finishing. This skill helps with fractions, money, and planning.

How it works

To work out percentages in Super Mario Maker, you need to:

Count how many coins you have collected
Count how many coins are in the level
Divide the number you have by the total number
Multiply that number by 100 to get the percentage

Examples you can see

Let's say you're playing a Super Mario Maker level and there are 20 coins in total. You've collected 10 coins. Here's how you work out what percentage you've collected:

Number of coins collected: 10
Total number of coins: 20
10 divided by 20 = 0.5
0.5 multiplied by 100 = 50%

So, you've collected 50% of the coins. Here's another example: If you have 15 coins and there are 30 coins in total:

15 divided by 30 = 0.5
0.5 multiplied by 100 = 50%

You've collected 50% again. Let's try a smaller example: If there are 5 coins and you've collected 2:

2 divided by 5 = 0.4
0.4 multiplied by 100 = 40%

You've collected 40% of the coins.

Try it as a mini adventure

Imagine you're on a Super Mario Maker adventure and you're trying to collect all the coins in a level. Here's a challenge for you: Adventure: The Coin Collection Quest You're on a mission to collect all the coins in a level. Here's what you need to do:

First, count how many coins are in the level
Then, count how many you've collected
Next, work out what percentage you've collected
Finally, see how many more coins you need to collect to get 100%

Let's say the level has 25 coins and you've collected 15. What percentage have you collected?

15 divided by 25 = 0.6
0.6 multiplied by 100 = 60%

You've collected 60% of the coins. Now, how many more coins do you need to collect to get 100%?

Total coins: 25
Coins collected: 15
25 - 15 = 10

You need 10 more coins to get 100%.

Common mistakes

Mistake: Forgetting to multiply by 100 to get the percentage
Why it happens: Kids often forget that to get a percentage, you need to multiply by 100.
Fix: Always remember to multiply your answer by 100 to get the percentage.
Mistake: Mixing up the number of coins collected with the total number of coins
Why it happens: It's easy to confuse which number is which when you're counting.
Fix: Double-check that you're dividing the coins collected by the total coins.
Mistake: Thinking that 50% means you have half of the coins
Why it happens: Some children might think 50% is just a number without understanding what it means.
Fix: Explain that 50% means half, so if there are 20 coins, 50% is 10 coins.

Parent and carer guide

Parents and carers can help children by:

Using a real game or level to practice counting coins
Encouraging children to explain how they found the percentage
Playing a game together where you both collect coins and calculate percentages
Using everyday examples like counting coins in a piggy bank to show how percentages work
Practicing with different numbers to build confidence

You can also ask questions like:

How many coins did you collect?
How many coins are there in total?
What percentage have you collected?
How many more coins do you need to collect?

Remember, it's okay if your child makes mistakes. They're part of learning. Keep it fun and encouraging.

FAQ

What is a percentage?

A percentage is a way of showing a part of a whole. It's always out of 100. For example, 50% means 50 out of 100.

How do I calculate a percentage?

To calculate a percentage, divide the number you have by the total number, then multiply by 100.

Why is learning about percentages useful?

Learning about percentages helps with money, shopping, games, and understanding how much you've done or collected.

Can I use this in real life?

Yes! You can use percentages to work out how much of your allowance you've spent, or how many questions you've got right on a test.

What if I have more coins than there are in the level?

If you have more coins than there are in the level, it means you've collected extra coins, which is great! But the percentage will still be calculated using the total number of coins in the level.
