Math textbooks now are keyed to graphing calculator functions. Believe me, it’s worth the investment. A student can graph a function in seconds, play around with the coefficients and immediately see how the graph changes. Your kids can use them for later classes in math and science, too.

I feel oldz. I wasn’t allowed anything more than a slide ruler in high school, and they wouldn’t even allow my slide ruler because it had too many scales on it. I had to get a “standard” slide ruler.

(My mother gave it to me; it came from Cleveland Institute of Electronics. It had a number of scales for calculating electronic formulae on it.)
