Mario Kart speed boosts maths mission

A practical mini-mission using speed boosts to practise ratio through questions, examples and child-friendly challenges.

Quick answer

By playing Mario Kart, you can learn about ratios by comparing how fast your kart goes with and without speed boosts.

Learning outcome

By the end of this page, you will understand how to compare speeds using ratios and solve simple ratio problems using Mario Kart examples. Success signs:

You can say how much faster one kart is compared to another
You can use the words "for every" and "to" when talking about ratios
You can solve a simple speed boost ratio problem
You can draw a picture to show a ratio of speed boosts

Why this matters

Ratios help us compare things that are different, like how fast one thing is compared to another. In Mario Kart, you can use ratios to know how much faster your kart goes when you use a speed boost. This skill is useful in real life too – like comparing how many cookies each person gets, or how many miles you can drive with a certain amount of fuel.

How it works

Ratios show how much of one thing there is compared to another. In Mario Kart, we can compare how fast your kart goes with and without a speed boost. For example:

Without a speed boost, your kart goes 10 units per second
With a speed boost, your kart goes 20 units per second

We can write this ratio as 10 : 20 or simplify it to 1 : 2. This means for every 1 unit of speed without a boost, you get 2 units of speed with a boost.

Examples you can see

Let’s imagine you're playing Mario Kart and you have two karts: Cart A:

Without speed boost: 15 units per second
With speed boost: 30 units per second

The ratio is 15 : 30, which simplifies to 1 : 2. Cart B:

Without speed boost: 20 units per second
With speed boost: 40 units per second

The ratio is 20 : 40, which simplifies to 1 : 2. So both karts get twice as fast with a speed boost! Here’s how you can draw this:

Kart	Speed without boost	Speed with boost	Ratio
Cart A	15	30	1 : 2
Cart B	20	40	1 : 2

Try it as a mini adventure

Mario Kart Speed Boost Challenge! You are racing in a Mario Kart tournament. You have two karts: Kart 1:

Without boost: 12 units per second
With boost: 24 units per second

Kart 2:

Without boost: 18 units per second
With boost: 36 units per second

Adventure Steps:

Find the ratio of speed with and without boost for Kart 1
Find the ratio of speed with and without boost for Kart 2
Compare the two ratios – are they the same?
Draw a picture showing how much faster Kart 2 is with its boost

Challenge: If you had 5 speed boosts, and each one makes your kart go 3 units faster, how much faster would your kart go in total? Answer: 5 boosts × 3 units = 15 units faster

Common mistakes

Mistake: Writing the ratio backwards, like 20 : 10 instead of 10 : 20.
Why it happens: Not paying attention to the order of numbers.
Fix: Always check that the first number is the smaller one, or the one you're comparing from.
Mistake: Forgetting to simplify the ratio.
Why it happens: Not knowing how to reduce fractions.
Fix: Divide both numbers by the same number until you can’t go any further. For 10 : 20, divide both by 10 to get 1 : 2.
Mistake: Thinking ratios are the same as addition.
Why it happens: Mixing up ratio and addition.
Fix: Remember, ratios compare parts, not total amounts.

Parent and carer guide

This is a fun way to teach ratios using Mario Kart! You can help your child by:

Playing Mario Kart together and discussing how fast karts go
Using everyday items to compare speeds – like how fast you walk vs. how fast you run
Encouraging your child to draw ratios or use blocks to show the speed boost
Practising the simplified ratio concept – 10 : 20 = 1 : 2
Noticing if they mix up the order of numbers in a ratio

Try asking questions like:

How much faster does your kart go with a boost?
Can you show me how you worked out the ratio?
What if you had 3 boosts – how much faster would you go?

This is a great chance to use real-life examples to help your child understand ratios. Keep it light and fun – your child is learning something new without even realising it!

Practice questions

Without boost: 8 units per second. With boost: 16 units per second. What is the ratio?
Without boost: 12 units per second. With boost: 24 units per second. What is the ratio?
Without boost: 5 units per second. With boost: 10 units per second. What is the ratio?
Without boost: 15 units per second. With boost: 30 units per second. What is the ratio?
Without boost: 20 units per second. With boost: 40 units per second. What is the ratio?

Answers:

8 : 16 = 1 : 2
12 : 24 = 1 : 2
5 : 10 = 1 : 2
15 : 30 = 1 : 2
20 : 40 = 1 : 2

FAQ

What is a ratio?

A ratio is a way to compare two things, like how fast one kart goes compared to another.

How do you simplify a ratio?

You simplify a ratio by dividing both numbers by the same number until you can’t go any further. For example, 10 : 20 becomes 1 : 2.

Why do we use ratios in Mario Kart?

Ratios help us understand how much faster one kart is compared to another, which helps in racing and strategy.

Can ratios be more than 2 numbers?

Yes! A ratio can compare more than two things. For example, if you have 3 karts with speeds 10, 15, and 20 units, the ratio is 10 : 15 : 20.

How can I practice ratios at home?

You can compare how fast you walk vs. run, or how many cookies each person gets. Try drawing pictures or using blocks to show ratios!
