Did you use the trick of using a map, two sticks, two wells, two triangles, and the sun to work out the circumference of the earth?
My college Calc prof spent the first two days showing how Einstein could have skipped five mathematical steps when working on his E=MC Squared concept. (It was the prof's thesis! Don't ask me, I lost my notes over a half century ago.)
No! I wouldn't know how to do that. But for example if you have a right triangle and know the 2 perpendicular sides you can find the hypertenuse by drawing it and measure it. I want them to be able to solve a problem by whatever mean. In life it's more important that you can solve the problem.
