Hidden Multiplication

Multiplication hiding in wheels on cars

Use cars in a car park to practise four equal groups.

Quick answer

Multiplication hiding in wheels on cars means using the number of wheels on cars to learn multiplication. If you see 3 cars and each has 4 wheels, you can multiply 3 × 4 = 12 wheels in total.

Learning outcome

By the end of this page, you will understand how to use the number of wheels on cars to make equal groups and multiply them. You will know that when you have 3 cars and each has 4 wheels, that’s 3 groups of 4, which equals 12 wheels. Success signs:

You can count how many wheels are on 1 car.
You can make equal groups of wheels.
You can multiply 3 × 4 to find how many wheels are on 3 cars.
You can solve problems like “How many wheels are on 5 cars?”

Why this matters

Multiplication helps you work out how many things you have when you have equal groups. When you see cars in a car park, you can use what you know about wheels to multiply and find how many wheels there are in total. This helps you in real life, like when you are shopping, playing games, or even counting your toys.

How it works

Let’s start with a simple idea: cars have wheels. Each car usually has 4 wheels. If you see 1 car, that’s 1 group of 4 wheels. If you see 2 cars, that’s 2 groups of 4 wheels. If you see 3 cars, that’s 3 groups of 4 wheels. To multiply, you can think of it as:

1 car = 1 group of 4 wheels
2 cars = 2 groups of 4 wheels
3 cars = 3 groups of 4 wheels

You can also think of it as repeated addition:

1 car = 4 wheels
2 cars = 4 + 4 = 8 wheels
3 cars = 4 + 4 + 4 = 12 wheels

Examples you can see

Let’s look at some real-life examples using cars and wheels. Example 1: 1 car

1 car has 4 wheels
So 1 × 4 = 4 wheels

Example 2: 2 cars

Each car has 4 wheels
2 cars = 2 groups of 4 wheels
2 × 4 = 8 wheels

Example 3: 3 cars

Each car has 4 wheels
3 cars = 3 groups of 4 wheels
3 × 4 = 12 wheels

Example 4: 4 cars

Each car has 4 wheels
4 cars = 4 groups of 4 wheels
4 × 4 = 16 wheels

You can even draw this! Draw 4 cars, and then draw 4 wheels on each car. Count all the wheels to check your multiplication.

Try it as a mini adventure

Let’s go on a car park adventure! Adventure: Car Park Counting Challenge You are going to the car park with your parent or carer. You see different numbers of cars. For each car, you count the wheels. Then you multiply to find how many wheels there are in total. Step 1: You see 1 car.

How many wheels does 1 car have?
1 × 4 = ?

Step 2: You see 2 cars.

How many wheels does 2 cars have?
2 × 4 = ?

Step 3: You see 3 cars.

How many wheels does 3 cars have?
3 × 4 = ?

Step 4: You see 4 cars.

How many wheels does 4 cars have?
4 × 4 = ?

Step 5: You see 5 cars.

How many wheels does 5 cars have?
5 × 4 = ?

Step 6: You see 6 cars.

How many wheels does 6 cars have?
6 × 4 = ?

Step 7: You see 7 cars.

How many wheels does 7 cars have?
7 × 4 = ?

Step 8: You see 8 cars.

How many wheels does 8 cars have?
8 × 4 = ?

Step 9: You see 9 cars.

How many wheels does 9 cars have?
9 × 4 = ?

Step 10: You see 10 cars.

How many wheels does 10 cars have?
10 × 4 = ?

Step 11: You see 11 cars.

How many wheels does 11 cars have?
11 × 4 = ?

Step 12: You see 12 cars.

How many wheels does 12 cars have?
12 × 4 = ?

You can also make a chart to show how many wheels you found each time. It helps you see the pattern!

Common mistakes

Mistake: Thinking 4 × 4 = 15.
Why it happens: A child might add 4 + 4 = 8, then add 4 more to get 12, and then add 3 more to get 15.
Correct answer: 4 × 4 = 16. You can check this by adding 4 + 4 + 4 + 4 = 16.
Mistake: Counting wheels on only one car and not multiplying.
Why it happens: A child might see 5 cars but only count 4 wheels.
Correct answer: If there are 5 cars, and each has 4 wheels, you multiply 5 × 4 = 20 wheels.
Mistake: Confusing the number of cars with the number of wheels.
Why it happens: A child might say 5 cars = 5 wheels.
Correct answer: 5 cars = 5 groups of 4 wheels = 20 wheels.

Parent and carer guide

As a parent or carer, you can help your child by:

Going to a car park together and counting wheels on different numbers of cars.
Using a chart or drawing to show how groups of 4 wheels add up.
Practising multiplication with 4s using skip counting: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48.
Using real objects like toy cars or blocks to show groups of 4.
Encouraging your child to say the multiplication out loud: “3 cars, 3 groups of 4 wheels = 12 wheels.”

FAQ

Why do cars have 4 wheels?

Most cars have 4 wheels so they can move smoothly and stay balanced. It also helps them carry people and things safely.

Can I use this to learn other times tables?

Yes! If you learn how to multiply by 4, you can use that to help with other numbers too. For example, if you know 4 × 5 = 20, you can use that to work out 5 × 4 = 20.

What if I see a car with 3 wheels?

That’s a special kind of car, like a tricycle or a motorbike. But for regular cars, we usually count 4 wheels.

How can I remember 4 times tables?

You can use skip counting: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. You can also use your fingers or draw groups of 4 to help.

Is multiplication like adding the same number many times?

Yes! Multiplication is like adding the same number over and over. For example, 3 × 4 means 4 + 4 + 4 = 12.
