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!
