What is a good video with a math connection for 5th and 6th graders? - educational catalogs

I can not find in the catalogs to level, but since it is not readily available in my local video store, I can not test. I do not really want to, without knowing to buy, when they will be sufficient. In particular I'm looking for something less than an hour is not merely a repetition of a lesson --- perhaps a biography of a famous mathematician, something about how math is used in various careers, or the likelihood or the filing of logic. It is something that I want a replacement, so that you can use if I need to be outdoors. Ideas?
