1000 Greater Than or Less Than | Numbers | Year 4 Maths Resources

## What you need to know

Things to remember:

• Everything else stays the same, only the 1000s change.
• “More than” is the same as adding and “less than” is the same as taking away
• If there is only 1 thousand and we take 1 thousand away, we don’t have any left!

Usually you will need to find something like:

1000 greater than 3244

Or

1000 less than 1677

Before starting, let’s look at some vocabulary:

“Greater than” is the same as saying “more than”, which we will need to add

“Less than” is the same as taking away

So, really, this topic is just adding and subtracting!

The easiest way to see how we do this is to split up a number into the thousands and “everything else”.

$$3244+1000 = 3000 + 244 + 1000 = 3000 + 1000 + 244 = 4000 + 244 = 4244$$

Tip: Notice that only the thousands changed, the other numbers stayed the same.

$$6534+1000 = 7534$$

$$928+1000 = 1928$$

When subtracting, we always put the 1000 on the right of the take away sign!

$$5677 - 1000 = 5000 + 677 - 1000 = 5000 -1000 + 677 = 4000 + 677 = 4677$$

Tip: Notice that the other numbers stayed the same and only the 1000s changed.

$$2345 - 1000 = 1345$$

$$4263 - 1000 = 3263$$

Tip: If there’s only one thousand, then it disappears when we subtract!

$$1232 -1000 = 232$$

$$1665 -1000 = 665$$

$$4782+1000 = 4000 + 782 +1000 = 4000 + 1000+782=5000+782=5782$$

$$1672 - 1000 = 1000 + 672 - 1000 = 1000 – 1000 + 672 = 0+672=672$$
