Three-Digit Numbers
Numbers that have three digits, ranging from 100 to 999, where the first digit represents hundreds, the second represents tens, and the third represents ones.
Place Value and Face Value
Face value is the digit itself, while place value depends on the digit's position in the number (Hundreds, Tens, or Ones).
Expanded Form
Writing a number by showing the value of each digit, such as 456 written as 400 + 50 + 6.
Comparing Numbers
Using symbols like greater than (>), less than (<), and equal to (=) to find out which three-digit number is bigger or smaller.
Ascending and Descending Order
Arranging three-digit numbers from smallest to largest (ascending) or from largest to smallest (descending).

Frequently Asked Questions
How do we read a three-digit number like 405?
We read it by combining the hundreds and ones places, skipping the tens place since it is zero: Four hundred five.
What is the difference between place value and face value?
Face value is the digit itself (like 5 in 352), while place value is the value of that digit based on its position (5 tens or 50).
How can I easily compare two three-digit numbers?
Always look at the hundreds digit first. The number with the bigger hundreds digit is larger. If the hundreds are the same, compare the tens digit, and then the ones digit.
