PLACE VALUE

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

Understanding the value of each digit in a number can help you with rounding, estimating and calculation. Once you know the place value column heading, this will be easy peasy!

Example: What is the value of the 6 in 2463871?

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.)

You can see that the 6 is in the Ten Thousands (10,000) column so therefore the value of the 6 is 60,000.

Example: Which number has the smallest value?

8392071 or 8329071

Again, place each digit in its place value column.

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.

Ah ha! They’re different! 2 is smaller than 9 so 83296071 has the smallest value.
