Comparing Three-Digit Numbers

About this worksheet

Comparison symbols get four different workouts on this 2nd grade Common Core sheet for 2.NBT.4. Part 1 scaffolds the routine: 438 and 429 arrive pre-split into hundreds, tens and ones, and students name which digit settled the comparison. Eight bare statements follow, including two equal pairs (516 and 444) and the reversal 342 versus 324. A Number Detective section asks for the greatest of three lookalikes in sets such as 812, 798 and 821, and the page ends on error analysis: Leo claims 398 beats 412 because 9 is bigger than 1, and students must talk him out of it.

What's inside this worksheet

Part 1: Place Value Check

Two scaffolded pairs (438 against 429, 615 against 598) with the digits already broken out and a line asking which digit helped you decide.

Part 2: Compare the Numbers

Eight statements to complete with >, <, or =, from 342 ___ 324 through 903 ___ 899.

Part 3: Number Detective

Circle the greatest number in sets A to C and the least in sets D to F, built from lookalikes such as 988, 899 and 989.

Part 4: Explain Your Thinking

Leo's wrong claim that 398 is greater than 412. Students refute it using place value, in writing.

Answer key

Symbols for all eight comparisons plus the model rebuttal comparing 4 hundreds against 3 hundreds.

How teachers use it

Which digit decided

Read Part 1's follow-up aloud and have students point at the deciding digit with a finger before writing any symbol.

Set F reveal

Set F (988, 899, 989) exposes anyone still reading left digits only. Mark it first when the pages come in.

Leo alone works

Question 11 stands alone as a five-minute writing prompt. Accept any answer that names hundreds before ones.
