Mathnet which started as a segment of "Square One TV," was a fun & funny adaptation of a familiar police procedural (specifically the 50's cop show, "Dragnet") which employed quality performances and solid writing to teach math concepts. It insulted neither the child nor adult viewer. Many actors who served as regulars and guest stars would pop up giving quality performances in primetime TV and in movies. If I could find DVD's of this series I'd buy them in a heartbeat.
