Place value is crucial in math, describing the value of each digit in a number.
A place value chart organizes digits by their place (ones, tens, hundreds, thousands, etc.).
The number 123 has a 1 in the hundreds place, 2 in the tens place, and 3 in the ones place.
The value of a digit is determined by its position in the number.

Comparing Numbers Using Place Value

The digit in a larger place value position represents a larger value.
For example, the 3 in 5,630 represents 30, while the 3 in 356 represents 300. This shows the 3 in 356 is larger than the 3 in 5,630.

Place value is essential for addition, subtraction, multiplication, and division.
It's also key for understanding and representing numbers in different contexts like money, time, and measurement.

Using Models to Understand Place Value
