Andrew’s HS math team in west Texas in the early 70s was best in Slide Rule, Number Sense. No “official” UIL State Championship at that time though. Roosevelt in San Antonio was more well-rounded in those two and much better in Science (my team), but Holmes (also San Antonio TX) had a slight lead in Math as a single event. (My wife’s team).
None of us was this dominant this long though.
Slide rules and pocket protectors: the mark of the science nerd!.................Yeah, I had them!........................
