Eight vertical addition problems, each paired with a generous work box, make up this three-digit addition with regrouping worksheet. Every problem requires carrying at least once, and several require regrouping twice, which makes the set a solid challenge for grades 2 and 3. The directions prompt students to regroup when needed and show all work below the problem.

This sheet fits naturally into a math unit on place value and multi-digit addition, whether you use it as a guided lesson tool or independent practice after you have introduced the concept. Completing it builds the habit of organizing column work clearly, tracking carried digits, and checking place value at each step, skills that carry directly into multi-digit multiplication later on.
