ORDERING NUMBERS

NC: Read, write, order and compare numbers up to 10,000,000 and determine the value of each digit.

Split the digits into their place value parts and then compare one digit at a time, starting from the left.

Example: Which is the largest?

5712924 or 5799924

Place each digit in a large number in its place value column. (Start from the Ones and then add as many columns as I need on the left.)

Starting from the largest value (ie. the left hand side), compare each digit column by column.

They’re the same, so let’s go on to the next column.

They’re the same, so let’s go on to the next column.

Yes! We found it! They’re different. 9 is bigger so 5799924 is bigger.

Example: Which is correct?

371004 > 361004 or 2811034 < 2811634

Compare each pair of numbers using their place value columns.

REMEMBER:

> means bigger than

< means smaller than

7 is bigger than 6 so 371004 is the bigger number. 371004 > 361004. This is correct!
