Standard

Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

Student language:

• "I can compare three-digit numbers using <, =, and >."

Explanation

About the Math, Learning Targets, and Rigor

This standard builds on the work of 2.NBT.1 and 2.NBT.3 by having students compare two numbers by examining the amount of hundreds, tens and ones in each number.

Students are introduced to the symbols greater than (>), less than (<) and equal to (=) in 1st Grade, and use them in 2nd Grade with numbers within 1,000.

Note: Students should have ample experiences communicating their comparisons in words before using only symbols in this standard.

To compare, students apply their understanding of place value. They first attend to the numeral in the hundreds place, then the numeral in tens place, then, if necessary, to the numeral in the ones place.
