Place Value in 4-Digit Numbers

Place Value in 4-Digit Numbers

• Understanding place value is crucial for working with numbers. Place value indicates the value of a digit based on its position within a number.

Identifying Place Values

• A four-digit number has thousands, hundreds, tens, and ones places.
• The rightmost digit represents the ones place.
• The digit to the left of the ones place represents the tens place.
• The digit to the left of the tens place represents the hundreds place.
• The digit to the left of the hundreds place represents the thousands place.

Examples of Place Value

• In the number 3,256:
  • The digit '6' is in the ones place, representing 6 ones.
  • The digit '5' is in the tens place, representing 5 tens (or 50).
  • The digit '2' is in the hundreds place, representing 2 hundreds (or 200).
  • The digit '3' is in the thousands place, representing 3 thousands (or 3000).

Practice Identifying Place Value

• Consider the number 7,832:
  • What digit is in the thousands place? (7)
  • What digit is in the hundreds place? (8)
  • What digit is in the tens place? (3)
  • What digit is in the ones place? (2)
