From doing geometry in 12 year old classes in 2002, to algebra in 14 yr classes, our experience never called for offloading the math onto the calculator. Whenever I'm helping my son with math homework I try to ensure pencil on paper is the first step we exhaust before any magical math steps.

It sounds like obvious old man get-off-my-lawn energy, but when I was growing up the kids running games on TI calculators were the ones who were curious and also tutored sufficiently to not have any problems with math.

That was never me, of course. I was too broke and ignorant to have a TI-84 until college, and only used it in one math class.
