Subtract 3-Digit Numbers (With Regrouping): what children learn

Regrouping can happen in the ones, the tens, or both. Each trade moves 1 from a bigger place to the next smaller place as 10.

Subtract 3-Digit Numbers (With Regrouping): worked example

452 - 187 = 265

2 - 7 needs a trade: 12 - 7 = 5 ones. Then 4 - 8 needs a trade: 14 - 8 = 6 tens. Then 3 - 1 = 2 hundreds. So 452 - 187 = 265.

Subtract 3-Digit Numbers (With Regrouping): a common mistake to watch for

Subtract 3-Digit Numbers (With Regrouping): how to help at home or in class

Before solving, have your child draw a small arrow above every column where the top digit is smaller than the digit below it. Those are the places that need a trade. Then cross out the digit being traded from and write its new value above in a different color, so it is hard to forget. When the arrows are right every time, they are ready for numbers with zeros in the middle.
