Reply #49: I agree that HS kids should need to know

econ and calculus - and any calculus class absolutely requires trigonometry...and trig does not need to be a standalone class - it should be taught along with algebra to speed the process. Statistics need to be included in a reasonable economics class and I don't like baby stats that make no mention of density functions and their integrals. The prob/stats does not need to prove the very intuitive Law of Large Numbers and it need not prove the Central Limit Theorem - that is best left for undergrads, but it should absolutely tell people what they are.

Someone below mentioned that basic econ needs stochastic calculus. I will draw the line there and say that such things are best left to undergrads majoring in econ, prob/stats, or derivatives valuations.

...and this is all very doable. I mean, is there any difference between 5th and 6th grade math? No, it is practically a repeat. Why repeat...go to the next level. Prealgebra in 6th grade is fine...then algebra and trig in 7th grade can set up people for pre-cal and intro to calc in 8th grade with calc in 9th grade. It is very doable.
