Subtracting 2 Digit Numbers Regrouping

Subtraction 2-Digit by 2-Digit (With Regrouping)

Description: Learn how to regroup (borrow) when subtracting two two-digit numbers.
Student Tips:

• Always start from the ones place. If the top number is smaller, regroup from the tens place.

• Remember to lower the tens by one and increase the ones by ten.

• Double-check your answer with addition.
  Teaching Instruction: Demonstrate regrouping visually with base-ten blocks. Gradually move to paper problems, reminding students to say aloud what they are borrowing and why.
