    Place value of multi-digit whole numbers

    Students will learn how to identify place value in multi-digit numbers. For example, in 4,396, the digit 3 represents 3 hundreds, because it's in the hundreds place.

    Next, students will learn how digits can be arranged to form the largest or smallest number. For example, given the digits 7, 1, 4, 2, the largest number would be 7421, and the smallest would be 1247.
