Place Value to 1000
Grade 2 · Math · Study Guide
Learn how the place of a digit in a number tells you its value, up to the thousands place.
Every number is made up of digits, and where a digit sits in a number tells you exactly how much it is worth. This is called place value!
In a three-digit number, the digits have three places: ones, tens, and hundreds. The digit on the far right is in the ones place. The digit in the middle is in the tens place, and the digit on the left is in the hundreds place. For example, in the number 342, the 3 means 3 hundreds (300), the 4 means 4 tens (40), and the 2 means 2 ones (2). Add them together: 300 + 40 + 2 = 342.
We can also write numbers in expanded form to show what each digit is worth. The number 587 in expanded form is 500 + 80 + 7. This helps us see the value of each digit clearly.
Numbers go all the way up to 999 in three digits. When you add one more to 999, you get 1,000, which has four digits. Understanding place value helps you compare, add, and subtract numbers like a math superstar!
