11 times table pattern clues

Quick answer

The 11 times table has a helpful pattern that makes it easier to learn: for numbers 1 to 9, you just repeat the digit twice. For larger numbers, you can add the digits and place the sum between them.

Learning outcome

By the end of this page, you will know how to use pattern clues to help you remember the 11 times table, and you will be able to quickly calculate 11 times any number from 1 to 12.

• You can say the 11 times table from 1 to 12
• You can multiply any number by 11 using a simple pattern
• You can spot when the pattern works and when it doesn’t
• You can explain why the pattern works for some numbers

Why this matters

Knowing your times tables helps you solve bigger maths problems quickly. The 11 times table is special because it has a fun pattern that makes it easier to remember. You’ll use this skill when you’re counting money, sharing items equally, or even in games and sports. Understanding patterns also helps you become a better problem solver!

How it works

There are two main patterns for the 11 times table:

1. For numbers 1 to 9, multiply by 11 by simply repeating the digit twice. For example: 3 × 11 = 33
2. For numbers 10 to 12, multiply by 11 by adding the digits and placing the sum between them. For example: 12 × 11 = 132

Let’s explore each pattern step by step.

Examples you can see

Let’s look at the 11 times table from 1 to 12:

Notice how easy it is for 1 to 9? Just repeat the number twice. But for 10 to 12, it’s a bit different. Let’s look at how we get 11 × 12:

1. Take the digits of 12: 1 and 2
2. Add them: 1 + 2 = 3
3. Place the sum between the original digits: 1 3 2
4. So, 11 × 12 = 132

Try it as a mini adventure

Imagine you are a space explorer and your spaceship needs to travel to 12 different planets. Each planet has 11 space rocks. How many space rocks will you collect in total? Let’s solve this using the 11 times table pattern:

1. Planet 1: 1 × 11 = 11 rocks
2. Planet 2: 2 × 11 = 22 rocks
3. Planet 3: 3 × 11 = 33 rocks
4. Planet 4: 4 × 11 = 44 rocks
5. Planet 5: 5 × 11 = 55 rocks
6. Planet 6: 6 × 11 = 66 rocks
7. Planet 7: 7 × 11 = 77 rocks
8. Planet 8: 8 × 11 = 88 rocks
9. Planet 9: 9 × 11 = 99 rocks
10. Planet 10: 10 × 11 = 110 rocks
11. Planet 11: 11 × 11 = 121 rocks
12. Planet 12: 12 × 11 = 132 rocks

Wow! That’s a lot of space rocks. Can you count them all? Try to use the pattern to quickly work out how many rocks you’d collect on each planet!

Common mistakes

• Mistake: Thinking 11 × 11 = 111
• Why it happens: Confusing the pattern with 11 × 10 = 110
• Fix: Remember that 11 × 11 = 121, and you can check by adding 1 + 1 = 2, then placing it between 1 and 1 to get 121

• Mistake: Forgetting to add the digits when multiplying by 11
• Why it happens: Rushing or not reading the pattern carefully
• Fix: Always split the number into digits, add them, then place the sum between them

• Mistake: Thinking 11 × 12 = 121
• Why it happens: Mistaking the pattern for smaller numbers
• Fix: Use the pattern: 12 → 1 + 2 = 3 → 132

Parent and carer guide

Help your child practice the 11 times table by:

1. Playing a quick game: say a number from 1 to 12, and have them multiply it by 11 using the pattern
2. Using everyday objects: if you have 11 toy cars, and there are 3 sets, ask how many cars in total (3 × 11 = 33)
3. Encouraging them to explain the pattern to you – this helps solidify their learning
4. Pointing out that the pattern works for 1 to 9, but for 10 to 12, they must add the digits
5. Practising with a chart or flashcards to help them memorise

Remember: it’s okay if they don’t get it right the first time. The pattern takes a bit of practice, but it’s a great way to build confidence in multiplication.

FAQ

What is the 11 times table pattern?

For numbers 1 to 9, multiply by 11 by repeating the digit twice. For numbers 10 to 12, add the digits and place the sum between them.

Why does this pattern work?

It’s a shortcut that uses place value and addition. When you multiply by 11, you are essentially adding the number to itself ten times, plus one more time.

Can I use this pattern for numbers bigger than 12?

For numbers 13 and up, the pattern becomes more complex and isn’t as reliable. It’s best to use regular multiplication or a calculator for those.

Is 11 × 11 = 111?

No, it’s 121. The pattern for 11 × 11 is: 1 + 1 = 2, so the answer is 121.

How can I remember the 11 times table?

Use the pattern: for 1 to 9, repeat the digit; for 10 to 12, add the digits and place the sum between them. Practice with flashcards or games!
