About these 3-Digit Addition and Subtraction worksheets and activities
In the early grades, students first encounter 3-digit addition and subtraction as they extend their understanding of place value and regrouping. By grade 2, learners practice adding and subtracting within 1000, often with visual supports like base-ten blocks and number lines. In grade 3, the focus shifts to fluency with regrouping across all place values, including problems that mix three-digit and two-digit numbers. These resources scaffold from concrete to abstract, helping students master the standard algorithm while building number sense.
Related concepts include place value, regrouping (borrowing and carrying), estimation, and word problems. The resources on this page target these skills through engaging themes like dragon eggs and real-world scenarios. Students develop mental math strategies, accuracy, and confidence as they progress from guided practice to independent work. The materials are teacher-authored and designed to be no-prep, classroom-ready, and easily differentiated for mixed-ability groups.
Using these in your classroom
Teachers can use this hub to select the right level for whole-group instruction, then differentiate for small groups and centers.

For review or assessment, choose problems that match your class's current focus, from basic regrouping to mixed operations. Mixing printable and digital resources allows you to support diverse learners, from struggling students needing scaffolded practice to advanced learners ready for challenge problems. All resources are classroom-ready and require no prep.
Standards alignment
These resources align with grade-level Common Core standards for Number and Operations in Base Ten, specifically the expectations for adding and subtracting within 1000 in grades 2 and 3. They support key skills like using place value understanding and properties of operations to perform multi-digit arithmetic.
