Description
Adding three-digit numbers with carrying is a big step in elementary math, and this triple digit addition regrouping worksheet gives 3rd graders the focused practice they need. Students work through fifteen vertical addition problems, adding two three-digit numbers and regrouping across the ones, tens, and hundreds places to find each sum.
This 3rd grade addition worksheet lays the problems out in a clean, easy-to-read grid so students can line up the place values and carry accurately. Print it for morning work, a math center, homework, or a quick review before a quiz. Each problem is numbered in its own circle so it never gets confused with the digits being added, and a full answer key is included so grading takes seconds.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- 15 three-digit addition problems that all require regrouping
The triple digit addition regrouping worksheet helps students in three ways. First, every problem requires carrying, so learners get repeated, targeted practice with the trickiest part of multi-digit addition. Second, the consistent column layout builds the habit of aligning place values neatly. Third, the included answer key lets teachers and parents spot regrouping mistakes quickly and reteach on the spot.
To extend the practice, have students check a few answers with base-ten blocks or a number line, or ask them to write an addition story problem that uses one of the sums. Partners can solve the same problem separately and compare their carrying steps, or explain their thinking aloud. At home, families can practice regrouping with play money or by adding up prices while shopping.
