Saying really big numbers can be difficult for kids, especially numbers with 5 or more digits.

Students that find saying big numbers difficult don’t realise that numbers are said in groups or ‘families’ of three  (ones, thousands and millions) and that the comma or space in numbers represent a place value word.

Saying Big Numbers Using Colour Coding

Latest research into learning maths, by Professor Jo Boaler, emphasises the importance of students not learning maths through memorization. We agree!!! Kids who rely on memory for their math understanding are on shaky ground, because the memory can FAIL!

In her books Mindset Mathematics Boaler shows that students will do better in maths if they are given the opportunity to visualize, play and investigate the maths concepts they are learning. Like in the Chinese proverb…

Hands on Learning Chinese Proverb

She talks about how colour-coding can help students visualise number patterns which helps them to connect everything together and build a deep understanding of mathematical concepts.

Our brain wants to think visually about mathematics, yet few curriculum materials engage students in visual thinking. The neuroscientists’ research shows the importance not only of visual thinking but also of students’ connecting different areas of their brains as they work on mathematics.Jo Boaler

So we have taken her expert advice to help with teaching numbers.

Comma or NO Comma?

Many countries use a comma to separate numbers but some, including Australia, are no longer using the comma, they just leave a space between the numbers.

It worth a discussion so that students don’t think the comma in numbers is the same as the comma in writing!  I mention both ways so that students can understand place value in a range of contexts and don’t get stumped if they see it a different way.

Read more about gaps and commas in numbers in this article.

How To Teach Big Numbers

Fun Comma Games

    1. Start by writing a 3 digit number in black pen, missing out the comma.
    2. Use the prompt: “The name of the comma in this 3 digit number is ‘Thousand’ “, use this to help you read the place value of any big numbers.
    3. Go back to the original number and add the comma using a different colour, in this case we used pink.
    4. The next step is to model to the students how to read the number from left to right. “Say the name of the number in front of the comma.” In this case it’s one, write this down in words under the digit, using black pen to match the colours
    5. Next point to the comma and say the name of the comma, “Thousand”, writing this down at the same time.
    6. Continue modelling how to say the number names of the rest of the digits in the number. In this case they are zeros so they are not said… an interesting discussion to also have with the students.
    7. Now run it altogether writing it down as you go.
    8. Now, build larger numbers in the tens of thousands and hundreds of thousands.


  • “The name of the pink comma is ‘thousand’.”
  • “Read the number in front of the comma (10).”
  • “Say the name of the comma (thousand)

9. Repeat the process for 100,000.
