Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons(Understand Place Value).
Write the symbols <, =, and > on the board. Remind students that these symbols tell us about the relative size of two numbers. Help students recall that the (<) symbol means “less than” and (>) means “greater than,” and that the “=” symbol means “the same as.” Explain that Mathematics is not always about “equals”, sometimes we need to know if a number is greater or less than another number.
Write the examples below on the board. Instruct several students to write numbers in the blanks that can make true comparative number sentences. Make sure students say the statements verbally.
