Place value tells us the value of a digit based on its position in a number. Each place is worth ten times as much as the place to its right.
Always read numbers by looking at the place of each digit. A digit’s value changes depending on where it is in the number.
To identify the place value of a digit, look at its position from right to left: ones, tens, hundreds, and thousands.
You can use a place value chart to help line up the digits. This makes it easier to see each digit’s value.
We can use base-ten blocks or drawings to show how each digit represents thousands, hundreds, tens, and ones.
Models help us “see” the number. Always check if the number matches the blocks: thousands, hundreds, tens, and ones.
Numbers can be written in standard form, expanded form, and word form. Each form shows the value of the digits in a different way.
Expanded form shows the value of each digit. Word form helps you say the number correctly when reading aloud.
