Skill 4G Two Digit Addition with Regrouping in One's Place You know the drill, if the sum is 10 or more when adding in the ones column we then add one group of ten to the tens column to the left. This was once called "carrying," but the math Guru's felt we should change this and now call it "regrouping" while some textbooks call it "renaming." I assume the reason for calling it "regrouping" is that it would help to clarify what is being done since we are moving one group of ten and combining (regrouping it) with the other tens in the tens place.
