Second grade is where subtraction stops being a fact to remember and starts being a procedure to run. Regrouping is the first bit of math that has a genuine method with steps, and most of the trouble children have with it comes from arriving too early: if the facts within 20 are still slow, borrowing gets bolted on top of counting and the whole thing collapses.
The fifteen free worksheets below climb that ladder in order. Get the facts within 20 quick, practice the column layout with no borrowing at all, hit a mixed page that forces the question of whether regrouping is even needed, then work through regrouping itself, from a guided sheet with boxes to a bare page with nothing to lean on. Every one is a printable PDF with no account and no watermark. Start wherever your class already is.

If your kids finish a unit and you're not sure what to do next, my honest advice: don't move on yet. Spend a week mixing these in as warm-ups. Fluency isn't a unit, it's a habit, and the sheet that builds it is usually the one they ask to do again.
