Place Value
Overview
Place value is the value of each digit in a number.
For two-digit numbers, there is the TENS place and the ONES place.
Let’s take a closer look at the place value for the number 12.
The 1 is in the TENS place, and the 2 is in the ONES place.
That’s because the number 12 is made up of 1 ten and 2 ones.
If you had 12 cups, you could make 1 stack of ten with 2 cups leftover.
Let’s take a look at the number 23.
The number 23 is made up of 2 Tens and 3 Ones.
You can also write this as 2 x 10 + 3 x 1
What happens if we have a number more than 99?
We discussed the ones place and tens place. If we take a look at a three-digit number like 123, we would need to add another column called the hundreds column.
The number 123 is made up of 1 Hundred, 2 Tens, and 3 Ones.
You can also write this as 1 x 100 + 2 x 10 + 3 x 1 which equals 132.
Take a look at one more example before you try the practice questions below.
How would you write the number 341 in a place value chart?
The number 341 is made up of 3 Hundreds, 4 Tens, and 1 Ones.
You can also write this as 3 x 100 + 4 x 10 + 1 x 1 which equals 341.
In higher grade levels, you will work with larger digits. Here’s a place value table to get a sneak peak.
