## What you need to know

Things to remember:

• To compare numbers we start from the biggest place value and work towards the right until one number is bigger than the other.
• To keep track of a list when order, cross them out as you go!
• Ascending means “getting bigger”.
• Descending means “getting smaller”.
• If you know your place values, it will make this topic much easier.

Ordering numbers is just like doing lots of comparisons, but how do we compare numbers?

Which is bigger, 556 or 565?

Starting with the 100s: Both have 5 100s (This doesn’t help).

Moving onto the 10s: Our first number has 5 10s, and our second number has 6 10s.

Because the pace value is bigger in the second number, we know this has to be biggest!

565 is bigger than 556.

When we order numbers, we are just doing lots of comparisons.

Put the following numbers in descending order (a fancy way of saying biggest to smallest)

56 256 567 346 222

We can put a line through as we go
