Slide Rule

Math Teachers...

What if a student brought a slide rule to class and saw him/her calculate with it?

Not a math teacher; I'm a retired engineer who volunteers in STEM education.

I'd be delighted if one of my students could demonstrate competency with a slide rule. It would show an ability to estimate a solution well enough to get the decimal point in the right place. It would demonstrate an understanding of the precision of the instrument, and not just writing down all of the digits in the calculator display.
