Double-Digit Addition and Subtraction Practice Set
By Christina G.
A short no-carry practice packet where students line up two-digit numbers in place-value columns and add or subtract ones and tens separately. It includes a worked example with a place-value grid and space for students to write their work beside each problem, making it a good fit for a focused 15-20 minute warm-up or independent practice block.
Customize for your classroom
Teacher Guide & Tips
- Use this as a warm-up or guided practice early in a unit on two-digit place value, after students have shown they can identify tens and ones.
- Discussion question: Why do we line up the ones under the ones and the tens under the tens before adding? What would happen if we didn't?
- Scaffold for struggling students: Have them use base-ten blocks or draw tens sticks and ones dots to model each problem before writing the numerical answer.
- Extension for advanced students: Ask them to explain how they could check a subtraction answer by adding, or to create their own two-digit problem that fits the no-regrouping pattern.
- Estimated time: About 15-20 minutes for the full set, depending on how many problems you assign.
