1 Multiply By Two Digits

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

3 23 x 12 Let’s estimate by rounding-

4 Two Digit Multiplication 23 x12 The first step is to make sure the place values are lined up. OnesTens

5 Two Digit Multiplication 23 x12 Begin with multiplying the bottom factor’s one’s place with the top factors one’s place. Think, 2 x 3 equals 6. 6 Circle the multiplier.

6 Two Digit Multiplication 23 x12 Next, multiply the 2 and the other 2. Think, 2x2=4 64

7 Two Digit Multiplication 23 x12 We are done with the first multiplier. Cross it out and circle the next multiplier (tens) We need to use a 0 for a place holder. Place the 0 under the 6 in the products line.

8 Two Digit Multiplication 23 x12 Next, begin to multiply the 1in the tens place with the top line factor. Think 1x3=

9 Two Digit Multiplication 23 x12 Think 1x2=

10 Two Digit Multiplication 23 x12 Finally, add the two product lines to find the final product Add the ones place. Add the tens place. Add the hundreds place. 2 X 23= X 23= 230

11 The product is 276
