How to teach 2-digit by 1-digit multiplication with regrouping

  1. 1

    Review carrying from addition first

    Since regrouping in multiplication works like carrying in addition, do a quick addition review if it's been a while since kids practiced it.

  2. 2

    Model one problem step by step

    Work through a sample problem like 47 x 3 on the board, narrating each multiplication and carry before assigning the sheet.

  3. 3

    Encourage writing the carried digit small

    Have kids write the carried number in a consistent spot above the tens column so it doesn't get lost or mixed up.

  4. 4

    Estimate before solving

    Ask kids to round and estimate the answer first (like 50 x 3 = 150) so they can catch major errors after computing.

Common mistakes kids make

  • Forgetting to add the carried digit after multiplying the tens place — remind kids to check for a small carried number before finishing.
  • Multiplying the tens digit before the ones digit — reinforce always starting with the ones place, just like in addition.
  • Writing the carried digit in the wrong column — have kids place it directly above the tens digit consistently.
  • Skipping the estimate step and turning in answers that are wildly off — build the habit of a quick mental estimate before checking work.

Tips for parents and teachers

  • Use graph paper or lined boxes to help keep digits aligned in columns.
  • Have kids underline the ones digit of the answer before adding the carried number so nothing gets missed.
  • Start with problems that don't require regrouping, then move to ones that do, so the new skill is isolated.
  • Review times tables briefly before this worksheet if basic facts still feel shaky.
