standard_description: Compare two numbers between 1 and 10 presented as written numerals.
problem_activity: Narrative
The purpose of this activity is for students to write the symbol or number that makes a comparison statement true. Students then read the comparison statement. This activity has two parts. In the first part, students are given two numbers with a blank space in which to write a comparison symbol that makes the statement true. After students write the symbol, they read the comparison statement. Reading the statement encourages students to relate the language of comparison to the symbols (MP6). In the second part of the activity, students are given a comparison symbol and either one number or neither number. Students determine a number or numbers that will make the comparison true.
MLR8 Discussion Supports.
Before pairs begin working together, remind students to use phrases such as greater than and less than. Model how to use these phrases when comparing two numbers. Invite students to chorally repeat the phrases in context.

[IMG]
Fill in each box with a number to make each statement true.
\(\boxed{\phantom{\frac{aaai}{aaai}}} > 78\)
\(39 < \boxed{\phantom{\frac{aaai}{aaai}}}\)
\(13 = \boxed{\phantom{\frac{aaai}{aaai}}}\)
\(\boxed{\phantom{\frac{aaai}{aaai}}} < \boxed{\phantom{\frac{aaai}{aaai}}}\)
\(\boxed{\phantom{\frac{aaai}{aaai}}} > \boxed{\phantom{\frac{aaai}{aaai}}}\)

Advancing Student Thinking
If students create statements that are not true, consider asking:
“Read your statement. How could you prove that it is a true statement?”
“What other numbers could you use to make this a true statement? Explain how you know.”
Activity Synthesis
Display
\(\boxed{\phantom{3}} > 78\)
.
“How did you know what number would make the statement true?” (I knew it had to be greater than 78 because I read the statement ‘blank is greater than 78’. I put in a number and read the statement out loud to see if it was true. I chose a number with more than 7 tens so I knew it would be greater than 78.)
Display
\(39 < \boxed{\phantom{3}}\)
.
“How did you know what number would make the statement true?” (I knew it had to be greater than 39 because I read the statement ‘39 is less than blank’. I put in a number and read the statement out loud to see if it was true. I chose a number with more than 3 tens so I knew that it would be greater than 39.)
Invite students to share comparisons they made for
\(\boxed{\phantom{3}}< \boxed{\phantom{3}}\)
and
\(\boxed{\phantom{3}} >\boxed{\phantom{3}}\)
.
\(\)
For each comparison shared, have the class decide if it is true or not.
