Where is multiplication hiding in LEGO Games vehicle wheels?

Count wheels on several vehicles using equal groups.

Quick answer

Multiplication is hiding in LEGO vehicle wheels when you count equal groups of wheels on different vehicles. For example, if you have 3 cars and each car has 4 wheels, you can multiply 3 × 4 to find the total number of wheels.

Learning outcome

By the end of this page, you will be able to count the wheels on LEGO vehicles by using equal groups and multiplication. Success signs:

You can tell how many wheels are on one vehicle
You can count how many vehicles you have
You can multiply the number of wheels by the number of vehicles
You can solve problems like "How many wheels are there on 5 cars?"

Why this matters

When you play with LEGO vehicles, you are already using maths! Counting wheels helps you understand how many parts make up a vehicle. This skill helps you in real life when you count things like:

How many wheels are on your bike or scooter
How many wheels are on a bus or truck
How many wheels are on your LEGO race car or fire truck

Multiplication helps you count quickly and easily, especially when you have many vehicles or many wheels.

How it works

Multiplication is like adding the same number many times. When you have vehicles with the same number of wheels, you can use multiplication to find the total. Let's imagine you have 4 LEGO cars, and each car has 4 wheels.

One car has 4 wheels
Two cars have 4 + 4 = 8 wheels
Three cars have 4 + 4 + 4 = 12 wheels
Four cars have 4 + 4 + 4 + 4 = 16 wheels

But instead of adding, you can multiply:

4 cars × 4 wheels = 16 wheels

Examples you can see

Let's look at some LEGO vehicles and count their wheels. Example 1: LEGO Cars

One car has 4 wheels
Three cars have 3 × 4 = 12 wheels

Example 2: LEGO Trucks

One truck has 6 wheels
Two trucks have 2 × 6 = 12 wheels

Example 3: LEGO Bikes

One bike has 2 wheels
Five bikes have 5 × 2 = 10 wheels

Example 4: LEGO Motorcycles

One motorcycle has 2 wheels
Four motorcycles have 4 × 2 = 8 wheels

You can draw these examples or use LEGO bricks to make your own wheels and count them.

Try it as a mini adventure

Adventure: LEGO Vehicle Wheel Hunt You are a LEGO engineer who needs to count all the wheels on your LEGO garage! Here's what you need to do:

Step 1: Find 3 LEGO cars in your garage
Step 2: Count how many wheels each car has
Step 3: Multiply the number of cars by the number of wheels on each car
Step 4: Add 2 trucks, each with 6 wheels, to your garage
Step 5: Count how many wheels are now in your garage

Let's do it together:

3 cars × 4 wheels = 12 wheels
2 trucks × 6 wheels = 12 wheels
Total wheels = 12 + 12 = 24 wheels

Can you find more vehicles in your LEGO set and count their wheels?

Common mistakes

Mistake: Thinking that 3 cars with 4 wheels each means 3 + 4 = 7 wheels.
Why it happens: Confusing addition with multiplication.
Fix: Remember that multiplication means "groups of" the same number. So 3 cars with 4 wheels each means 3 × 4 = 12 wheels.
Mistake: Counting the wheels on one vehicle, then just adding them up without multiplying.
Why it happens: Not yet understanding that multiplication is repeated addition.
Fix: Use groups to help you multiply. For example, 5 cars with 4 wheels each = 5 × 4 = 20 wheels.
Mistake: Forgetting that a motorcycle has 2 wheels.
Why it happens: Not remembering the number of wheels on different vehicles.
Fix: Make a list or draw a picture of your vehicles and their wheels to help you remember.

Parent and carer guide

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

Playing with LEGO vehicles together and counting wheels
Using real-world examples like bikes, cars, and buses to practice
Encouraging your child to draw or build their own vehicles and count wheels
Reinforcing the idea that multiplication means equal groups
Using simple language like "3 cars, 4 wheels each = 3 times 4"

Try this 5-minute activity:

Ask your child to find 4 LEGO cars in their set
Count how many wheels each car has
Ask them to multiply the number of cars by the number of wheels
Check the answer by adding the wheels one by one

If your child gets stuck, help them by drawing a picture or using actual LEGO bricks to show the groups.

Practice questions

How many wheels are on 2 LEGO cars if each car has 4 wheels?

Answers:

2 × 4 = 8 wheels
3 × 6 = 18 wheels
5 × 2 = 10 wheels
4 × 2 = 8 wheels
6 × 4 = 24 wheels

FAQ

What is multiplication?

Multiplication is a way to add the same number many times. For example, 3 × 4 means 3 groups of 4, which is 4 + 4 + 4 = 12.

Why do we use multiplication?

Multiplication helps us count quickly when we have equal groups. It's faster than adding the same number over and over.

Can I use LEGO to learn multiplication?

Yes! You can use LEGO bricks to make equal groups and then multiply. For example, 4 groups of 3 bricks = 4 × 3 = 12 bricks.

What if I forget how many wheels a vehicle has?

You can draw a picture, make a list, or look at real vehicles around you to remember. For example, a bike has 2 wheels, a car has 4 wheels, and a truck has 6 wheels.

How can I practice multiplication at home?

Count things around your house in equal groups. For example, how many legs are on 3 chairs? (3 × 4 = 12 legs). Or how many wheels are on 5 bikes? (5 × 2 = 10 wheels).
