Number & Operations in Base Ten

Recognizing that, for 3-digit numbers, the digits represent the amount of ones, the amount of tens, and the amount of hundreds.

The listing of worksheets and other math resources below are related to the following standard extracted from the Common Core Standards For Mathematics:

Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
1. 100 can be thought of as a bundle of ten tens – called a “hundred.”
2. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
