The Pumped Up World of PreAlgebra

This is a fun video about PreAlgebra.
From their site:
'The Standard Deviants team uses their colorful approach to make math entertaining. Features topics including integers, multiplication, division, rounding, fractions, and ratios.'

It's free. Just download and watch it on your computer. I haven't watched the whole thing yet, just the very beginning, but it looks promising... 

If you like it, they also made a video for Basic Math.  Integers are included in this Basic Math video, so if you need to review Adding, Subtracting, Multiplying or Dividing Integers, it's there!
