Step by step

The question

Question: count back by 100s from 900 to 300.

1 Start at 900

Here is a number line.

2 Jump by 100s

Each jump is 100 less.

We say the number where we land.

3 Write the numbers

Now we write them in a row.

We stop at 300.

4 Check

Look at the last two digits.

They stay 00.

Only the hundreds change.

Yes!

It works.

Let's look back.

First: start at 900.

Then: jump by 100s.

Then: write the numbers.

Last: check.
