1. Multiply By Two Digits

2. Let’s Review Factors- Numbers multiplied together Product- The answer in a multiplication equation

3. Let’s estimate by rounding- 23 x 12

4. Two Digit Multiplication The first step is to make sure the place values are lined up. 23 x 12 Tens Ones

5. Two Digit Multiplication Circle the multiplier. Think, 2 x 3 equals 6. Begin with multiplying the bottom factor’s one’s place with the top factors one’s place. 23 x 12 6

6. Two Digit Multiplication Think, 2x2=4 Next, multiply the 2 and the other 2. 23 x 12 4 6

7. Two Digit Multiplication We are done with the first multiplier. Cross it out and circle the next multiplier (tens). 23 x 12 We need to use a 0 for a place holder. Place the 0 under the 6 in the products line. 4 6 0

8. Two Digit Multiplication Next, begin to multiply the 1in the tens place with the top line factor. Think 1x3=3. 23 x 12 4 6 3 0

9. Two Digit Multiplication Think 1x2=2. 23 x 12 4 6 2 3 0

10. Two Digit Multiplication Add the ones place. Finally, add the two product lines to find the final product. 23 Add the tens place. x 12 4 6 Add the hundreds place. 2 X 23= 46 + 2 3 0 10 X 23= 230 2 7 6

11. The product is 276
