What is Place Value?
Place value is a way to tell how much each digit in a number is worth based on where it is in the number. In a number, the position of each digit tells us its value. The farther left a digit is, the bigger its value!
For example, in the number 4,532,789:
- The 4 is in the millions place, so it means 4,000,000.
- The 5 is in the hundred thousands place, which means 500,000.
- The 3 is in the ten thousands place, so it means 30,000.
- The 2 is in the thousands place, which means 2,000.
- The 7 is in the hundreds place, so it’s worth 700.
- The 8 is in the tens place, so it’s worth 80.
- The 9 is in the ones place, which means 9.
So, when we put all those values together, the number 4,532,789 means 4 million + 500 thousand + 30 thousand + 2 thousand + 700 + 80 + 9.
Writing Numbers in Digit Form
Sometimes, numbers are written out in words, and we need to change them back into digits. Here’s an example:
- “Five million, three hundred twenty-four thousand, one hundred fifty-seven” becomes 5,324,157.
To do this, we find where each word fits in the place value chart:
- “Five million” means the 5 goes in the millions place.
- “Three hundred twenty-four thousand” means the 324 goes in the hundred thousands, ten thousands, and thousands places.
- “One hundred fifty-seven” means the 157 goes in the hundreds, tens, and ones places.
By knowing place value, you can write any big number correctly!
