Introduction to 1000
When we add 1 to 999, we get the smallest 4-digit number, which is written as 1000 and read as 'one thousand'.
Place Value of 4-Digit Numbers
Every digit in a 4-digit number has a place value: Thousands, Hundreds, Tens, and Units (Ones), starting from the right.
Expanded Form
Writing a number as the sum of the place values of each of its digits, such as 4567 = 4000 + 500 + 60 + 7.
Comparing and Ordering Numbers
To compare two 4-digit numbers, first look at the thousands place, then hundreds, tens, and units to decide which is greater or smaller.
Predecessor and Successor
The predecessor is 1 less than a given number, and the successor is 1 more than the given number.

Face value is the digit itself, while place value is the value of the digit based on its position (Thousands, Hundreds, Tens, or Ones) in the number.
