What This Standard Means
What Students Need to Do
- Students compare two three-digit numbers by checking hundreds, then tens, then ones if needed. They say which number is greater, less, or equal and write >, <, or = between the numbers.
What Mastery Looks Like
- A student can explain that 462 > 459 because both numbers have 4 hundreds, but 6 tens is more than 5 tens. They can compare 407 and 470 by the tens place and record 407 < 470.
Common Misconceptions
- Some students compare ones first, so they say 348 is greater than 352. Others reverse < and >, or think 405 and 450 are equal because they contain the same digits.
How to Assess It
- Exit ticket: Compare 508 and 580 using >, <, or =. Circle the place that decided and write the comparison in words.

Ways to Teach It
Build 364 and 346 with base-ten blocks, then have students point to the first place that differs and place a symbol card between them.
Write 509 and 590 on the board and ask, “Which is greater, and which place tells you?”
Give partners two sets of 0–9 digit cards; each builds a three-digit number, then they choose a comparison symbol and explain.
Post two school book drive totals, 238 and 283; students write a comparison and name the place that determines the larger total.
