Place Value

Overview

Your student will be learning:

• the value of a digit is determined by its place in the number.

Example: The digit 2 in the the number 8,273 is in the hundreds place and has the value of 200.

• the comma between the thousands place and the hundreds place, is read as the word “thousand” and we do not say “and” after the hundreds place.

Example: 8,273 is read “eight thousand, two hundred seventy-three.”

• numbers can be represented in many different forms.

Expanded form: 8,000 + 200 + 70 + 3

Expanded notation: (8 X 1,000) + (2 X 100) + (7 X 10) + (3 X 1)

• decomposing numbers is any way to break apart a number.

Example: 253 can be decomposed as:

• 200 + 53
• 100 +153
• 200 + 25 + 25 + 3

(The ability to be flexible with numbers will help your child develop number sense and mental math strategies.)
