12 times table common mistakes

Quick answer

When learning the 12 times table, children often make mistakes like forgetting that 12 x 1 = 12, confusing 12 x 5 with 12 x 6, or thinking 12 x 10 = 1200. These errors can be fixed by using visual models, real-life examples, and consistent practice.

Learning outcome

By the end of this page, you will understand the 12 times table and be able to avoid common mistakes when multiplying by 12.

• You can recite the 12 times table from 0 to 12.
• You can spot and correct common mistakes in 12 times table calculations.
• You can use arrays, repeated addition, or real-life examples to solve 12 times table problems.
• You can explain why certain answers are wrong and how to fix them.

Why this matters

Knowing your 12 times table helps with many everyday tasks. For example, if you're buying 12 items that cost £5 each, you need to know that 12 x 5 = 60 to check your money. It also helps when you're working out how many days are in a certain number of weeks or how many items you have if they come in groups of 12, like eggs or pencils.

Learning the 12 times table also builds a strong foundation for more complex maths later on, such as fractions, division, and algebra. It helps you think quickly and confidently about numbers.

How it works

When you multiply by 12, you are adding the same number 12 times. For example, 3 x 12 means 3 groups of 12. You can also think of it as 12 + 12 + 12.

Here's how to work out 12 x 12:

1. Break it into parts: 10 x 12 + 2 x 12
2. 10 x 12 = 120
3. 2 x 12 = 24
4. Add them together: 120 + 24 = 144

This method helps you remember bigger answers by using smaller, easier parts.

Examples you can see

Let’s look at some examples of 12 times table calculations and how to do them correctly.

Try it as a mini adventure

Imagine you are a cake decorator and you need to make a special birthday cake for a child who loves 12 candles. Each candle costs 12p. If you want to make 12 candles, how much will they cost?

Step 1: You need 12 candles

Step 2: Each candle costs 12p

Step 3: So you need to calculate 12 x 12p

Step 4: 12 x 12 = 144p

Step 5: That’s £1.44

Now, what if you want to make 12 candles for 5 children? How much will that cost?

Step 1: 5 children x 12 candles each = 60 candles

Step 2: 60 candles x 12p = ?

Step 3: Use the method: 60 x 10 + 60 x 2 = 600 + 120 = 720p = £7.20

Common mistakes

• Mistake: Thinking 12 x 5 = 65
• Why it happens: Confusing 12 x 5 with 12 x 6
• Fix: Remember that 12 x 5 = 60 because 5 x 12 = 60. You can check by counting 12, 24, 36, 48, 60.

• Mistake: Thinking 12 x 10 = 1200
• Why it happens: Adding too many zeros by mistake
• Fix: 12 x 10 = 120. Think of it as 12 groups of 10, not 1200.

• Mistake: Forgetting that 12 x 1 = 12
• Why it happens: Not remembering that any number times 1 is itself
• Fix: Remember that 12 x 1 = 12. This is a basic rule in multiplication.

• Mistake: Thinking 12 x 7 = 77
• Why it happens: Mixing up the numbers or making a small error
• Fix: Use the method of 10 x 7 + 2 x 7 = 70 + 14 = 84

• Mistake: Confusing 12 x 9 with 12 x 8
• Why it happens: Similar numbers can be tricky to remember
• Fix: Use the 10 and 2 method: 10 x 9 + 2 x 9 = 90 + 18 = 108

Parent and carer guide

Helping your child with the 12 times table can be fun and simple:

• Use real-life examples: Ask your child to count 12 eggs in 3 cartons or 12 pencils in 4 boxes.
• Practice with arrays: Draw 12 rows with 4 items in each row and count them together.
• Use games: Play multiplication card games or use apps that focus on times tables.
• Be patient: It's normal for children to make mistakes. Use them as learning opportunities.
• Encourage practice: A few minutes of daily practice can make a big difference.

Don’t worry if your child gets confused sometimes. The key is to keep practicing and to make it fun!

FAQ

What is the easiest way to learn the 12 times table?

The easiest way is to break it into parts. For example, 12 x 7 = (10 x 7) + (2 x 7) = 70 + 14 = 84.

Why is the 12 times table harder than others?

The 12 times table is harder because it includes larger numbers and there are more facts to remember. However, using patterns and methods can make it easier.

How can I help my child remember the 12 times table?

You can help by using visual aids, arrays, games, and real-life examples. Practicing regularly and making it fun will help your child remember.

What are some real-life uses of the 12 times table?

Some real-life uses include counting items in groups of 12 (like eggs or pencils), calculating money for 12 items, and working out time (like 12 hours in a half-day).

Can I use a calculator for the 12 times table?

Yes, you can use a calculator, but it's better to learn the table first so you can solve problems quickly without it.
