Why this matters

When you make mistakes in maths, it’s a chance to learn even more. Misconceptions cards help you see what goes wrong and how to fix it. These cards are great for learning because they make mistakes clear and fun to talk about. They’re used in schools, at home, and in maths clubs to help children understand tricky ideas.

How it works

Printable misconception cards are like little learning tools that show a maths problem with a wrong answer. Then, they show the correct answer and explain how to fix it. These cards help you learn by seeing a mistake and then thinking about how to correct it. Here’s how they work:
  1. Look at the maths problem on the card
  2. Find the wrong answer
  3. Think about why it's wrong
  4. Try to fix the mistake
  5. Learn from the explanation

Examples you can see

Let’s look at some example misconception cards for different maths topics. Example 1: Addition mistake

Problem: 5 + 3 = 8

Wrong answer: 5 + 3 = 7

Correct answer: 5 + 3 = 8

Explanation: You might think 5 and 3 make 7, but if you count 5 fingers and then 3 more fingers, you get 8 fingers in total.

Example 2: Multiplication mistake

Problem: 4 × 3 = 12

Wrong answer: 4 × 3 = 10

Correct answer: 4 × 3 = 12

Explanation: 4 groups of 3 make 12, not 10. You can count 3 + 3 + 3 + 3 to get 12.

Example 3: Division mistake

Problem: 10 ÷ 2 = 5

Wrong answer: 10 ÷ 2 = 3

Correct answer: 10 ÷ 2 = 5

Explanation: If you split 10 sweets between 2 people, each person gets 5 sweets. Not 3.

Try it as a mini adventure

Mini Adventure: The Maths Mistake Mission You are a detective who finds maths mistakes in a magical land! Each day, you get a new mission card with a maths problem and a wrong answer. You must find the mistake, fix it, and explain how you did it. Today’s mission:
  • Problem: 6 + 4 = 10
  • Wrong answer: 6 + 4 = 9
  • Correct answer: 6 + 4 = 10
  • Your job: Explain why 6 + 4 is not 9, and how to get 10.
  1. First, count 6 fingers on one hand and 4 fingers on the other.
  2. Count them all together: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
  3. So 6 + 4 = 10, not 9!
  4. Write your explanation in your maths notebook.

Common mistakes

Here are some common mistakes children make in maths and how to fix them.
  • Mistake: 5 + 3 = 7
  • Why it happens: Kids might count 5, then count 3 more, but get confused and say 7 instead of 8.
  • Fix: Use fingers or objects to count again and check your answer.
  • Mistake: 4 × 3 = 10
  • Why it happens: Confusing multiplication with addition, thinking 4 + 4 + 4 = 10.
  • Fix: Draw 4 groups of 3 objects to see that 4 × 3 = 12.
  • Mistake: 10 ÷ 2 = 3
  • Why it happens: Not understanding that division means sharing equally.
  • Fix: Use counters or draw 10 circles and split them into 2 groups.

Parent and carer guide

Parents and carers can help children use misconception cards in 5-10 minutes by:
  • Choosing a card that matches your child’s current learning
  • Reading the problem and wrong answer together
  • Letting your child explain why the answer is wrong
  • Working together to find the right answer
  • Encouraging your child to write or draw how they fixed the mistake
What to say:
  • “Let’s look at this problem together.”
  • “Why do you think this answer is wrong?”
  • “Can you show me how you would solve it?”
What not to worry about:
  • It’s okay if your child makes mistakes – they help you learn!
  • Don’t rush – take time to talk through each card.
  • Focus on understanding, not just getting the right answer.

Practice questions

  1. What is wrong with this answer? 7 + 2 = 8
  2. Fix this multiplication mistake: 5 × 4 = 18
  3. Explain why 12 ÷ 3 = 4 is correct
  4. What is the correct answer to 3 + 9 = ?
  5. How would you fix 6 × 2 = 11?
Answers:
  1. 7 + 2 = 9, not 8
  2. 5 × 4 = 20, not 18
  3. 12 ÷ 3 means splitting 12 into 3 equal parts, so each part is 4
  4. 3 + 9 = 12
  5. 6 × 2 = 12, not 11
