Skill 5A Three Digit Addition with Regrouping You know the drill, if the sum is 10 or more when adding in the ones column that 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 call it "regrouping." Some textbooks call it "renaming." I assume they believed that calling it "regrouping" would help 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. Here we simply want to determine if your student does know how to get answers to a simple regrouping problem. Answer the 3 digit problem. |
