Videos for "Defining 3 Digit Numbers"

Students will need to be able to identify which part of a three digit number is the hundreds, which part of a three digit number is the tens, and which digit of a two digit number is the ones. For example, in the number 193 there is one hundred, nine tens, and three ones.

Standard code and description: 2.NR.1.1; Explain the value of a three digit number using hundreds, tens, and ones in a variety of ways.
