Math3-5
Adding and Subtracting One and Two Digit Numbers, Grade 3
By Aidan S.
A practice worksheet set for 3rd graders that builds addition and subtraction fluency with one- and two-digit numbers, including regrouping (carrying) and number-line strategies. Students show their work in boxes under each problem, and a worked example walks through 47 + 36 step by step.
Customize for your classroom
Teacher Guide & Tips
- Use this as independent practice after a whole-class mini-lesson on regrouping, roughly 20 to 30 minutes.
- Discussion question: Why did we write the 3 and carry the 1 when we added the ones? Ask students to explain the place-value idea in their own words.
- Scaffold for struggling readers: Pair them with a partner, provide base-ten blocks, and have them model the worked example before solving the independent problems.
- Extension for advanced students: Ask them to create their own two-digit addition problem that requires regrouping in both columns and explain how they solved it.
- Estimated time: about 25 minutes for the full set, depending on how many problems you assign.
