Subtraction 2-Digit by 1-Digit (With Regrouping)
Description: Practice subtracting a one-digit number from a two-digit number that requires regrouping (borrowing).
Student Tips:
If the top ones digit is smaller, regroup by borrowing 1 ten.
After regrouping, subtract as usual.
Check by adding your answer back to the subtracted number.
Teaching Instruction: Model regrouping with base-ten blocks — show how one ten can be broken into ten ones. Transition to written problems, stressing neat organization.
