I'm always looking for fun ways to help teach multiplication to my kids. I found this guys' videos online--and they are really cool. He also has some free and low-cost apps---but IMHO, everything you need is here.

 

I was excellent in math...getting As all the way through calculus and statistics. Still, I realize in retrospect that I was good at "plug and chug" but I never really "got" math until I started teaching it to my kids. :)

He has lots more on his youtube channel. There's also a video using a normal phone which teaches you the 7s and 3s.
