1. Seek The Multiplication Treasure 2009-2010

2. Copy this problem. Multiply the factors in the top row by the digit in the ones place in the second factor. 342 x 23 3 4 2 x 3 26 1 Since 4 3=12 Carry the 1 and write down the 2 10 Multiply 3 2Multiply 4 3Multiply 3 3 + 1

3. Now you will multiply the top factor by the tens digit in the second factor. In this problem, you multiply by the 2 in the tens place or 20. 342 x 23 3 4 2 x 3 2610 2

4. Since the 2 actually represents 2 tens or 20, we will want to put a zero in the ones place in the second row of our work before we multiply anything else. 342 x 23 3 4 2 x 3 2610 2 0

5. Multiply the 2 times every digit in the top factor and write the answer in the second row below the line. 342 x 23 3 4 2 x 3 2610 2 0486

6. To check to see if you are ready to add, count the number of digits in the second factor. 342 x 23 3 4 2 x 3 2610 2 048 There are two digits in the second factor. 6

7. Since there are two digits in the second factor there should be two rows of numbers to add to get the product. 342 x 23 3 4 2 x 3 2610 2 048 There are two digits in the second factor. 6 one two

8. Since the number of digits matches the number of rows, we now add the rows together to get the product of the original problem. 342 x 23 3 4 2 x 3 2610 2 048 There are two digits in the second factor. 6 one two +

9. Since the number of digits matches the number of rows, we now add the rows together to get the product of the original problem. 342 x 23 3 4 2 x 3 2610 2 0486 + 7866

10. Work the following problem following the steps used in the previous problem. 914 x 48

11. Work the following problem following the steps used in the previous problem. 914 x 48 7312 36560 1 + 43,872

12. Work the following problem following the steps used in the previous problem. 767 x 89 6903 61360+ 68,263 66 55
