Keep sending them. I enjoy them.
I gave the first one to all of the teachers in my building as well as to my
Calc II students. As far as I know, only one instructor other than myself
worked the Einstein quiz and one of my students worked it.
By the way, in my last post the last sentence which was quite convoluted.
What I meant to say was that students learn that irrational numbers fit
along side of rational numbers as lengths when they use the Pythagorean
theorem and get decimal approximations for the lengths like the square root
of 7. (What a concept--and in Basic Math no less! I got this in Modern
Algebra. Remember Dedikind Cuts and Bruises? The idea that rational
numbers and irrational number fit "tightly" together was never presented to
me in the lower levels.) In reverse, putting the calculated length for one
of the sides of a right triangle in decimal approximation form, helps them
understand that the Pythagorean theorem makes reasonable sense. Couple this
with teaching students how to approximate square roots by the nearby square
roots of perfect squares and the calculator is transformed to a teaching
tool as well as a computational tool.
