4th Grade Multiplication Math Challenge

1. First watch this method http://www.mathtrain.tv/play.php?vid=141 

2. Now open Tux paint and do the same problem as they did in the video.

3. Next work the problem 42 x 56 using the trick you saw above in #1.

4. Does it work the same? 

5. Next, watch the lattice method http://www.mathtrain.tv/play.php?vid=229 

6. What was your answer for #3 above?

7. How can you use the first method to derive the answer for 42 x 56?

8. Before you give an answer for #7, try some other 2 digit problems to see if your new trick will work. You can use Tux paint to work more problems using the method in number 1 & 5.

9.  Find the calculator on the computer and use it to check your answers.

10.  Write the problems that you worked, with their answers, on a piece of paper.  (no need to show your work on the paper because you are doing it in Tux.) Sign and turn in.

After you do #10, you may review the multiplication tables using the various resources at the Multiplication Link.
