Carrying the one: regrouping worksheets that show where it goes
The hard part of 52 minus 27 is not the subtraction. It is remembering where the borrowed ten went. The boxes on this sheet give it a home.
Watch a seven-year-old do 52 minus 27 and you can see the exact moment the borrowed ten gets lost. They cross out the 5, write a 4 somewhere near it, and then forget to make the 2 a 12. The arithmetic is fine. The bookkeeping is the problem, and bookkeeping needs a place to happen.
What the sheet looks like
The regrouping worksheet generator prints 9, 12, 16 or 20 stacked problems in addition, subtraction or a mix, with 2-digit numbers, 3-digit numbers or both. The regrouping control is the one that matters: always, so every problem carries or borrows; never, for a child who is not there yet; or mixed, so the child has to decide. The scaffold can be nothing, place-value headers reading H T O above the columns, or dashed regrouping boxes above each column for the carried one or the borrowed ten. Three-digit subtraction includes borrowing across a zero.
Why it works
- The regrouping boxes give the carried digit a fixed spot. Once it always lives in the same place, it stops getting lost.
- Mixed regrouping is where the thinking happens. A child doing an always sheet learns to borrow on autopilot; a mixed sheet makes them check the ones column first every time.
- Borrowing across a zero, as in 403 minus 157, gets its own share of problems on 3-digit sheets. It is the step most children get wrong and most worksheets avoid.
Who it suits
Two-digit addition with headers is late grade 1. Two-digit subtraction with always regrouping is the classic grade 2 sheet. Three-digit mixed with no scaffold is grade 3. If a child does not yet see 52 as five tens and two ones, go back to the place value worksheet first, because the boxes only make sense once the columns do.
Nine problems with boxes is a good first day. Twenty with no scaffold is a good last one.
