What this worksheet covers
This is a 20-problem sheet — one page to work through, one page of answers to check against. What makes this set particular: all of the twenty problems require regrouping and numbers reach 983. Grade 3, Number & Operations in Base Ten, Common Core 3.NBT.2: that is the exact slot this page fills.
Skills practiced
The skill underneath these problems is the standard algorithm, including regrouping across zeros. To finish it, a student has to carry or borrow across place-value columns without losing a digit. Fluency, not just correctness, is the target here — accurate and unhurried is the mark to aim for.
How to use this worksheet
Work it straight through, then check against the key together rather than handing it back marked. Asking the student to find their own error teaches more than seeing it circled. Ask the student to re-work one missed problem from scratch rather than correcting the answer in place — the second attempt shows whether the method changed.
One mistake to watch for
Borrowing across a zero fails: 500 − 237 comes out as 373 or 263.
The student tries to borrow from a column that has nothing, and either skips it or takes from the wrong place.
Do the cascade with base-ten blocks: break one hundred into ten tens, then one of those tens into ten ones. Write the two crossed-out digits on the page so both steps are visible.
