Teacher Resources
Teaching Notes

Teach the 'borrowing across zeros' strategy by demonstrating how to regroup from the first non-zero digit. Reinforce place value understanding as the foundation for this complex regrouping.

Vocabulary
Borrowing: Taking value from a higher place.
Zeros: Placeholders needing regrouping.
Common Mistakes
  • Forgetting to regroup or regrouping incorrectly when multiple zeros are present.
  • Borrowing from the wrong place value or skipping a zero.
  • Not adjusting all place values (tens, hundreds) after borrowing from the hundreds.
Differentiation
SupportUse place value charts or visual models to illustrate regrouping.
ChallengeCreate multi-digit problems with three or more zeros in the minuend.
Discussion Questions
  • Why is it especially tricky to subtract when there are zeros in the middle of a number?
  • What does it mean to 'regroup' or 'borrow' in the context of subtraction?
  • How does understanding place value help us when subtracting across zeros?
  • Can you think of a real-life situation where you might need to subtract across zeros?
Extension Activities
  • Subtract numbers ending in zeros.
  • Practice regrouping to 100.
  • Create subtraction stories.
Parent Tip

Use a place value chart to show how to borrow over zeros.
