Understanding Big Numbers

Place value helps us know what each digit in a number means. In fourth grade, you'll work with numbers up to the millions!

• The value of each digit depends on its place (ones, tens, hundreds, thousands, etc.).
• Reading and writing large numbers becomes easy when you understand place value.

Comparing and Rounding

When you compare numbers, you decide which is greater or smaller. Rounding means making a number simpler but close to its value.

• Round 4,652 to the nearest hundred: 4,700.
• Compare 56,789 and 65,789: 65,789 is greater.

Real-World Uses

Place value is used in reading prices, population numbers, and scores in games!
