These worksheets / assessments align with the Common Core State Standard 5.NBT.1. (Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.)
Students are required to break down numbers and represent them in multiple ways. They are required to determine if a digit in the number is 1/10 or 10 times greater than another digit.
The second page of each document asks students to compare digits in two different numbers and determine how much larger they are.
Generally I will teach the core knowledge of the benchmark then use one page as classwork, one page as homework, and one page for an assessment.
