Why this matters

A maths diagnostic quiz is like a doctor's check-up for your child's maths. It helps find out if they are doing well or if they need extra help. This is important because maths builds on itself. If a child doesn’t understand something early on, it can make later maths harder. A quiz helps parents and teachers see what your child already knows and what they still need to learn. It can also show if your child is ready for new challenges or if they need more practice with basics.

How it works

A maths diagnostic quiz usually has questions about:
  • Arithmetic – addition, subtraction, multiplication, and division
  • Fractions – parts of a whole
  • Decimals – numbers with a decimal point
  • Percentages – parts out of 100
  • Reasoning – solving problems using maths
The quiz is not about getting the right answer – it’s about understanding what your child can do and where they need support. The quiz might be:
  • Short and simple
  • Done online or on paper
  • Adapted to your child’s level
It can be done in a few minutes, or it can take longer. The most important thing is that it helps everyone understand how your child thinks about maths.

Try it as a mini adventure

Imagine you are a detective trying to solve a maths mystery. You have a treasure map, but to find the treasure, you need to answer some clues. Each clue is a maths question. Clue 1: What is 12 × 13? Clue 2: What is 3/4 of 16? Clue 3: If a box holds 100 stickers and you have 3 boxes, how many stickers do you have in total? Clue 4: What is 0.6 + 0.2? Clue 5: If 20 children are in a class and 1/4 of them are wearing glasses, how many children are wearing glasses? You must solve each clue to find the next part of the treasure map. Let’s see how many you can solve!

Common mistakes

  • Mistake: Thinking a quiz is just about getting the right answer. Why it happens: Some children and parents think a quiz is like a test where they must get everything right. Fix: Remember, a quiz is about understanding how your child thinks, not just the final answer.
  • Mistake: Not using the quiz results to help the child. Why it happens: Some parents finish the quiz and forget to look at the results. Fix: Use the results to plan fun maths activities or extra practice.
  • Mistake: Thinking the quiz is too hard or too easy. Why it happens: If a child gets many questions wrong, they might feel discouraged. Fix: A quiz that’s too hard is a sign to start with easier questions. A quiz that’s too easy means your child is ready for more.

Parent and carer guide

As a parent or carer, here’s how you can help your child with a maths diagnostic quiz:
  • Choose a quiet time to do the quiz together
  • Don’t rush – let your child think through each question
  • Ask your child to explain how they got their answer
  • Use the results to find games or activities that match your child’s level
  • Don’t compare your child to others – every child learns at their own pace
If your child gets stuck on a question, try:
  • Breaking the question into smaller parts
  • Using objects like counters or blocks to help
  • Encouraging them to try a different way to solve the problem
Remember, the quiz is not about being perfect – it’s about understanding how your child learns and what they can do.
