Twenty three-digit subtraction problems, every one needing at least one regroup, sometimes two. This is where borrowing gets real: children have to regroup tens into ones and hundreds into tens, and occasionally borrow across a zero.
Give each problem room and encourage neat rewriting of the digits above each column. Estimating first is a powerful check. If two-column borrowing is overwhelming, go back to 2-digit subtraction with regrouping for a few days.
Tips for using it
- Work one column at a time and rewrite the new digits above the old ones.
- Check by adding the answer and the bottom number; you should get the top number.
