Learning outcome

By the end of this page, you will understand what a maths diagnostic quiz is and how it helps you learn more about your maths skills. You will know how to answer questions about times tables, three-digit numbers, fractions, and word problems.

Why this matters

Knowing what you already know in maths helps you grow faster. A maths diagnostic quiz is like a map that shows where you are and where you want to go. It helps teachers and parents know if you need more practice with times tables, or if you are ready for bigger challenges. It also helps you see your own progress and feel proud of what you can do.

How it works

A maths diagnostic quiz has different types of questions:
  • Times tables – like 2 x 3 or 5 x 6
  • Three-digit numbers – like 345 or 789
  • Fractions – like half or a quarter
  • Word problems – questions that use words to describe maths
You might be asked to:
  1. Count in 2s, 5s, or 10s
  2. Write numbers in words or digits
  3. Share items equally
  4. Solve a problem using maths

Examples you can see

Let’s look at some examples from a maths diagnostic quiz for age 7 to 8. Example 1: Times Tables
  • What is 2 x 6?
  • What is 10 x 4?
  • What is 5 x 7?
Example 2: Three-Digit Numbers
  • Write 456 in words.
  • What number is 7 hundreds, 3 tens, and 9 ones?
Example 3: Fractions
  • If you have a pizza cut into 4 equal pieces and you eat 1 piece, what fraction have you eaten?
  • Draw 1/2 of a circle.
Example 4: Word Problems
  • If there are 3 groups of 5 apples, how many apples are there altogether?

Try it as a mini adventure

Adventure: The Maths Explorer’s Quest You are a brave explorer who has found a treasure map. To find the treasure, you must solve maths puzzles. 1st time: You see a number line from 0 to 20. Count in 2s. What number do you land on after 5 jumps? (Answer: 10) 2nd time: You find a box with 30 sweets. You want to share them equally between 5 friends. How many sweets does each friend get? (Answer: 6) 3rd time: You see a pizza cut into 8 equal slices. You eat 3 slices. What fraction of the pizza did you eat? (Answer: 3/8) 4th time: You need to count in 5s from 0. What number do you land on after 6 jumps? (Answer: 30) 5th time: You see a number 456. How many hundreds, tens, and ones are there? (Answer: 4 hundreds, 5 tens, 6 ones)

Common mistakes

  • Mistake: Thinking 2 x 6 = 14
    Why it happens: Mixing up the times table facts.
    Fix: Use your fingers or count in groups to check. 2 groups of 6 = 6 + 6 = 12.
  • Mistake: Writing 345 as "three hundred forty five" instead of "three hundred and forty five"
    Why it happens: Not knowing when to use "and" in numbers.
    Fix: Remember that "and" goes between hundreds and tens, like "three hundred and forty five".
  • Mistake: Saying 1/4 of a pizza means 1 piece out of 4 pieces
    Why it happens: Confusing what "quarter" means.
    Fix: Remember that a quarter is 1 out of 4 equal parts.
  • Mistake: Adding 10 + 10 = 20, but thinking 10 x 10 = 20
    Why it happens: Mixing up multiplication and addition.
    Fix: Remember that 10 x 10 means 10 groups of 10, so it’s 100.
