1. STEPS FOR MULTIPLYING A 2-DIGIT NUMBER BY ANOTHER 2-DIGIT NUMBER With Regrouping

2. Multiply with Regrouping STEP 1: Find the number in the ones position in the second 2-digit number of the problem and underline it.

3. EXAMPLE: 46 46 X 33

4. STEP 2: Multiply the number you underlined by the ones digit and tens digit of the first two-digit number. Don’t forget to regroup as needed! Write your answer in ROW1.

5. EXAMPLE: 1 46 46 X33 ROW 1 138 ROW 2

6. STEP 3: Write a zero in the ones position of ROW 2 of your answer.

7. EXAMPLE: 46 46 X 33 X 33 ROW 1 138 ROW2 0

8. STEP 4: Find the number in the tens place in the same 2-digit number where you underlined the ones place of the problem and draw a box around it.

9. X 3 3 ROW 1 138 ROW2 0 EXAMPLE: 46 46

10. STEP 5: Multiply the number that you just drew a box around by all the numbers on the top row of the problem, starting with the ones place. Don’t forget to regroup as needed! Write your answers in ROW 2 of your answer.

11. X 33 X 33 ROW 1 138 ROW2 1380 EXAMPLE: 1 46 46

12. STEP 6: Add ROWS 1 and 2 in your answer.

13. EXAMPLE: 1 1 46 46 X 33 X 33 1 ROW 1 138  Partial Product ROW2 + 1380  Partial Product 1518 1518
