Add 2-Digit Numbers (With Regrouping): what children learn
Regrouping (carrying) happens when the ones add to 10 or more: 10 ones become 1 ten. For 27 + 15, 7 + 5 = 12, so write 2 and carry 1 ten, then 1 + 2 + 1 = 4 tens.
Add 2-Digit Numbers (With Regrouping): worked example
27 + 15 = 42
7 + 5 = 12 ones. Write 2 and carry 1 ten. 1 + 2 + 1 = 4 tens. So 27 + 15 = 42.

Add 2-Digit Numbers (With Regrouping): how to help at home or in class
Set out a bag of dried beans and several small cups. Build 38 as three cups of ten beans plus 8 loose beans, then add 6 more loose beans. When the loose beans reach ten, your child snaps ten into a new cup and counts the cups again. Repeat with other numbers before any carrying is written, so the small 1 above the tens column has meaning. They are ready to move on when they can explain where that 1 came from.
