problem_activity: Narrative
The purpose of this activity is for students to compare three-digit numbers based on their understanding of place value. They are invited to explain or show their thinking in any way that makes sense to them. A number line is provided. Students may revise their thinking after locating the numbers on the number line, or may choose to draw diagrams to represent their thinking. During the activity synthesis, methods based on comparing the value of digits by place are highlighted.
For the last problem, students persevere in problem solving as there are many ways to make most of inequalities true but students will need to think strategically in order to fill out all of them. In particular, 810 can be used in the first, second, or fourth inequality but it needs to be used in the fourth because it is the
only
number on the list that is larger than 793.
Representation: Develop Language and Symbols.
Represent the problem in multiple ways to support understanding of the situation. For example, have one group member place the numbers on a number line to verify which number is greater. Another option is to have one group member make the numbers using base-ten blocks to prove which is greater.

Groups of 2
“In the warm-up, you saw that different forms of writing a number can help you think about the value of each digit.”
Write
\(564\phantom{3} \boxed{\phantom{33}}\phantom{3}504\)
on the board.
“What symbol would make this expression true? Explain.” (>, because they both have 500, but the first number has 6 tens or 60 and the second number has 0 tens.)
Activity
“Today you will be comparing three-digit numbers by looking at place value.”
“If it helps, you can use base-ten diagrams or expanded form to help you think about place value.”
“Try it on your own and then compare with your partner.”
5 minutes: independent work time
5 minutes: partner work time
Monitor for students who compare the numbers without drawing base-ten diagrams or using a number line.

Advancing Student Thinking
If students write comparison statements that are not true, consider asking:
“Could you read each statement aloud?”
“How did you know your statement is true?”
“How could you use the base-ten diagram or number line to help you show whether your statement is true or false?”
Activity Synthesis
Display
\(564 > 504\)
.
Display
\(500 + 60 + 4 > 500 + 4\)
.
“We decided that this was a true statement. How does the expanded form of these numbers help justify our thinking?” (We can see the value of each place, so we can compare each digit.)
Invite previously selected students to share how they compared numbers without drawing diagrams or using the number line.
