Add 3-Digit Numbers (With Regrouping): what children learn
Regrouping can happen in the ones, the tens, or both: 10 ones make 1 ten and 10 tens make 1 hundred.
Add 3-Digit Numbers (With Regrouping): worked example
258 + 147 = 405
8 + 7 = 15 ones: write 5 and carry 1 ten. 1 + 5 + 4 = 10 tens: write 0 and carry 1 hundred. 1 + 2 + 1 = 4 hundreds. So 258 + 147 = 405.
Add 3-Digit Numbers (With Regrouping): a common mistake to watch for
Kids forget to carry, or forget to add the carried number.
Add 3-Digit Numbers (With Regrouping): how to help at home or in class
Try partial sums as a way to see why carrying works. For 367 + 285, write the ones total (12), the tens total (140) and the hundreds total (500) on separate lines, then add them to get 652. Next solve the same problem in a column with carrying and compare. Seeing both give 652 makes the small carried digits make sense. They are ready to move on when they can carry in both columns and still pass an estimate.
