Place Value, Compare, and Round Numbers
Created by Shaunak Ghosh
You will learn what each digit is worth in big numbers up to 1,000,000. You will practice the ten-times place value pattern, write numbers in different forms, compare numbers using symbols, and round numbers to different places with confidence.
Requirements
- Count by 10s and 100s
- Read and write numbers at least to 1,000
- Know ones, tens, and hundreds places
- Add and subtract with whole numbers
What you'll learn
- Find the value of any digit in a whole number up to 1,000,000, and explain it using a place-value chart.
- Explain the ten-times relationship between neighboring place values, and use it to rename quantities in different units.
- Read and write large whole numbers with correct size words (thousand, million) and sensible zero use.

1
Find the value of a digit
Learn how much a digit is worth based on its place (ones, tens, hundreds, thousands, and more). Practice finding a digit’s value in big numbers up to 1,000,000.

2
Each place is ten times bigger
See how moving left makes a digit worth 10 times more, and moving right makes it worth 10 times less. Use examples like 700 ÷ 70 = 10 to explain the pattern.

3
Convert between place value units
Practice renaming numbers in different place value units, like turning thousands into hundreds or tens. Work up to hundred-thousands (example: 4,000 = 40 hundreds).

4
Write numbers in words and digits
Read and write whole numbers up to 1,000,000 in standard form (digits) and word form. Practice placing commas correctly and using zeros when needed.

5
Build and read expanded form
Break a number into the sum of its place values (expanded form) and put it back together. Pay special attention to zeros so you don’t skip a place.

6
Compare numbers using place value
Compare two numbers up to 1,000,000 by checking digits from the biggest place to the smallest. Use >, <, or = and explain your thinking.

7
Round whole numbers to any place
Round numbers to the nearest ten, hundred, thousand, or more by looking at the digit to the right. Practice tricky cases like when the deciding digit is 5 and when rounding changes another digit.

Rounding tables and rounding puzzles
Round the same number to different places by filling in a table. Then solve rounding puzzles where you use clues to figure out the hidden number.
