Lego Studs times-table story

A playful story page showing how LEGO studs can teach arrays in real life.

Quick answer

LEGO studs can help you learn multiplication by showing how equal groups make arrays!

Learning outcome

By the end of this page, you will understand how to use LEGO studs to show multiplication as equal groups and arrays, and you'll be able to solve multiplication problems by counting the studs in rows and columns. Success signs:
  • You can make a multiplication array using LEGO bricks
  • You can count the total number of studs by grouping them in rows and columns
  • You can solve multiplication problems by looking at LEGO arrays
  • You can explain how arrays show multiplication

Why this matters

Multiplication is all around us, and LEGO studs help you see it clearly. When you build with LEGO, you're already using multiplication without even realising it. If you have 3 rows of 4 studs, that's 3 groups of 4, which equals 12 studs. This is multiplication in action. Understanding this helps you with:
  • Sharing snacks equally
  • Counting toys or books
  • Building better LEGO creations
  • Learning your times tables faster

How it works

Multiplication is like making equal groups. When you use LEGO studs, you can see these groups as rows and columns. Here's how to think about it:
  1. Look at your LEGO brick and count how many studs are in each row
  2. Count how many rows there are
  3. Multiply these two numbers together to find the total number of studs

Examples you can see

Let's imagine you're building a LEGO house with a window. Your window is made of 4 rows of 3 studs each. How many studs do you need?
  1. There are 4 rows
  2. Each row has 3 studs
  3. So 4 × 3 = 12 studs
Here's another example: If you have a LEGO car with 2 rows of 5 studs each, how many studs make up the car's body?
  1. There are 2 rows
  2. Each row has 5 studs
  3. So 2 × 5 = 10 studs
Let's try a bigger one. Your LEGO castle has 6 rows of 4 studs for the tower wall. How many studs are in the wall?
  1. There are 6 rows
  2. Each row has 4 studs
  3. So 6 × 4 = 24 studs

Try it as a mini adventure

LEGO Array Builder Challenge! You're a LEGO architect building a new city. Your first project is a small shop with a roof made of LEGO studs.
  1. Shop roof: 5 rows of 3 studs
  2. Shop windows: 2 rows of 4 studs each
  3. Shop door: 3 rows of 2 studs
How many studs do you need in total for your shop?
  1. Roof: 5 × 3 = 15 studs
  2. Windows: 2 × 4 = 8 studs
  3. Door: 3 × 2 = 6 studs
  4. Total: 15 + 8 + 6 = 29 studs
Can you make your own LEGO array with different rows and columns? Try it with 7 rows of 2 studs, or 3 rows of 9 studs!

Common mistakes

  • Mistake: Counting the rows and columns wrong
    Why it happens: It's easy to lose track when counting
    Fix: Use your fingers or count aloud to keep track
  • Mistake: Adding instead of multiplying
    Why it happens: You might forget that equal groups are multiplication
    Fix: Remember: "rows × columns = total studs"
  • Mistake: Confusing rows and columns
    Why it happens: Sometimes it's hard to tell which is which
    Fix: Draw a small sketch to help you see rows and columns

Parent and carer guide

Parents, you can help your child by:
  • Using LEGO bricks to show multiplication as arrays
  • Asking questions like: "How many rows do you see?" and "How many studs in each row?"
  • Building together and counting the studs as you go
  • Encouraging your child to explain their thinking
  • Practicing with different LEGO arrangements
For 4-6 year olds, focus on simple arrays like 2 rows of 3. For 7-9 year olds, try larger arrays. For 10-12 year olds, introduce the concept of area as multiplication of length and width.

Practice questions

  1. How many studs in 3 rows of 4 studs?
  2. How many studs in 5 rows of 2 studs?
  3. How many studs in 4 rows of 6 studs?
  4. How many studs in 2 rows of 8 studs?
  5. How many studs in 6 rows of 3 studs?
Answers:
  1. 3 × 4 = 12 studs
  2. 5 × 2 = 10 studs
  3. 4 × 6 = 24 studs
  4. 2 × 8 = 16 studs
  5. 6 × 3 = 18 studs

FAQ

What is a multiplication array?

A multiplication array is a way to show multiplication using rows and columns. Each row has the same number of items, and each column has the same number of items.

How can I use LEGO to learn multiplication?

You can make arrays with LEGO studs by arranging them in rows and columns. Count the rows and columns to find the multiplication fact.

Why is learning multiplication with LEGO helpful?

LEGO helps you see multiplication as equal groups. This makes it easier to understand and remember multiplication facts.

Can I use any LEGO brick?

Yes! You can use any LEGO brick with studs. Try different sizes to see how the arrays change.

What if I don't have LEGO bricks?

You can use anything that comes in equal groups, like counters, coins, or drawn dots. The idea is the same!
