Understanding Numbers and Place Value

The Magic of Place Value

Numbers are more than just digits—they have places! Place value tells us how much each digit is worth.

Breaking Down Numbers

In the number 352, the 3 is in the hundreds place, the 5 is in the tens, and the 2 is in the ones. This means:

  • 3 hundreds = 300
  • 5 tens = 50
  • 2 ones = 2

So, \( 352 = 300 + 50 + 2 \).

Why Place Value Matters

Understanding place value helps you:

  • Read and write large numbers
  • Understand money and measurements
  • Solve addition and subtraction with bigger numbers

Everyday Uses

Place value is everywhere—from house numbers to phone numbers and prices at the store!

Examples

  • Reading 1,205 as one thousand, two hundred five.

  • Realizing in \$56, the 5 stands for 50 and the 6 stands for 6.

In a Nutshell

Place value helps you know what each digit in a number means.
