I was discussing a unit on logarithms with a friend today and he asked if seeing one of these would help my students’ understanding:
I had to admit that as I’ve never used a slide rule, I didn’t have a clue if it would help them or not. He seemed shocked (he claimed it wasn’t my age that led him to believe I would have used one). He thought it would be part of either my math or math ed coursework. Maple? Yep. Slide Rule? Nope.
So I’m wondering, am I the only math teacher who hasn’t used a slide rule?
