Regrouping Concepts in Subtraction
A conceptual introduction to borrowing by exchanging one ten for ten ones using manipulatives.
Key Questions
- What is actually happening to the value of a number when we borrow a ten?
- Justify why we need to 'borrow' from the tens place when we don't have enough ones to subtract.
- Construct a visual representation of subtracting 15 from 32 using regrouping.
