How to teach this

Ask for a quick estimate first (6,000 − 2,000 is about 4,000), then work right to left. Two or three borrows in one problem is normal here. A child who gets the ones right and the thousands wrong usually skipped reducing a digit after a borrow; circle every crossed-out digit as a check.

Watch for: Kids subtract the smaller digit from the bigger one whichever is on top (8 − 2 instead of 12 − 8). The top number is the one being taken from; the order matters. Kids borrow but forget to reduce the digit they borrowed from. Cross it out and write the new digit every time.

Common questions about 4th grade subtraction with regrouping

How large are the numbers?
Four-digit minus four-digit. Every problem regroups in at least one column.
Can my child check the answers?
Add the answer to the number that was subtracted; it should give the top number. The answer key is on the second page too.
