Year 4 Maths – Identifying Written Numbers KS2 Revision
What you need to know
Things to remember:
- We write our numbers as we read them
- If we don’t say any any hundreds, tens, or units then we write a 0.
In a test you might need to find a number in a list, so let’s see how we do this.
Find seven thousand, eight hundred and fifty-seven in the following list:
8557 7585 5857 7857 7855
We can do this by writing down the numbers as we read them.
Seven thousand
7
Eight hundred
78
Fifty-seven
7857
So, our answer would be:
8557 7585 5857 7857 7855
We can also think of it as adding.
7000 + 800 + 57 = 7857
When we don’t have any units, tens, or hundreds we just write down a 0.
“Write five thousand, and fifty-four.”
Five thousand
5
We didn’t say any hundreds
50
Fifty-four
5054
So, our answer is 5054!
