Subtracting Two-Digit Numbers (With Regrouping)
Using concrete objects and pictorial representations to subtract two 2-digit numbers, crossing the tens boundary.
Key Questions
- Explain the process of regrouping (borrowing) when the ones digit in the top number is smaller.
- Critique different methods for subtracting with regrouping, such as using a number line or base ten blocks.
- Construct a word problem that requires subtraction with regrouping to solve.
