Multiplication problems

I need help with teaching multiplication to my non-Aspie, Anita in 3rd grade.
She is normally very good and quick at learning pretty much anything you put in front of her.

mneumonic devices and lots of practice.
I have 2 ideas.
1 - School House Rock. They have multiplication songs that can help with memorization of multiplication facts. I bet there are a bunch of us that can still sing "3 is a Magic Number". They have DVD's with all the songs on them available. Teachers have used them with both my 10 year old dd and 13 yo dd and it has been really helpful.
2- Computer multiplication games. Try funbrain.com- http://www.funbrain.com/. Also, here is the link to the multiplication games on gamequarium - http://www.gamequarium.com/multiplication.html
You can also make more worksheets easily at "Math Fact Cafe" http://www.mathfactcafe.com/
Thanks,
There are a couple other easy tricks for the 9s that works for single digits.
1) Take the number that 9 is paired with (in 9x8 it would be 8). subtract 1 from that number and that is the 10s digit. (8-1=7 so 7 is in the 10s place). Then 9 minus that number (9-7=2) and that answer is the ones place. 9x8=72
2) hold your ten fingers out in front of you. What ever 9 is multiplied by count your fingers off from the left to that number. put that finger down. The fingers on the left are the 10s digit and the ones on the right are the ones. So say 9x5 you count 5 fingers from the left and put that one down. You have 4 fingers on the left of that finger and 5 on the right. 9x5=45.
