**Year 4 Maths – 1000 Greater Than or Less Than** *KS2 Revision*

## What you need to know

**Things to remember:**

- Everything else stays the same, only the
**1000**s 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

## Example Questions

Question 1: What is 4782+1000?

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

Our answer is 5782.

Question 2: What is 1672 - 1000?

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

** **

Our answer is 672
