Here you practice writing big numbers neatly and with the right separator.
Look at the given number and write it out yourself.
Example: 245,080
Say it out loud as you write: two hundred and forty-five thousand and eighty. The separator sits before the last three digits, the hundreds, tens and ones.
Tip: count three digits from the right and put the separator there.
The numbers written in show the answer.
Example
For parents
What does this exercise practice?
Writing big numbers up to 1,000,000 safely and with correct thousand grouping.
Common pitfalls
The separator is often forgotten or put in the wrong place. Always count from right to left in groups of three, then put the separator before the last group of three.
How to practice at home
Let your child write down big numbers from everyday life, such as a population or a car's mileage, and check the separator together.
