Hands-On Three-Digit Subtraction Station Rotation for Grade 3
By Brenda F.
A station-based packet that walks 3rd graders through subtracting three-digit numbers with base-ten blocks, using regrouping (trading) from the hundreds place to build place-value understanding. It includes key-term definitions, a worked example like 325 - 152, and hands-on build-and-break steps designed for small-group rotations.
Customize for your classroom
Teacher Guide & Tips
- Use this as a rotating station block of roughly 45 to 60 minutes, with students moving through the stations in small groups while you circulate to check their trades.
- Discussion question: Why does trading one hundred for ten tens leave the total value unchanged, and how does the block model show that?
- Scaffold for struggling readers: Provide a laminated key-terms card and have students act out each step with blocks before writing numbers, reading each step aloud together.
- Extension for advanced students: Ask them to create their own three-digit subtraction problem that requires regrouping from both the tens and hundreds places, then explain each trade.
- Plan about 10 minutes per station, including time to build, trade, and record answers.
