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

13
Are you up to the adventure of finding the multiplication treasure? Remember X (multiplication) marks the spot!

14
Choose from the following problems, at least two from each column. Solve them on Multiplication Graph Paper and pass in to your teacher. (Don’t forget to write your name on your paper.) 32 X 26 28 X 18 46 X 22 53 X 34 125 X 23 532 X 16 208 X 58 246 X 31 53 X 344 2,125 X 24 To Review the Demonstration again, click on the Treasure Chest.
