It’s Elementary (School), My Dear Watson

[Rescued from my old blog.]

From Time magazine, June 18, 1956:

“[M]athematics has the dubious honor of being the least popular subject in the curriculum… Future teachers pass through the elementary schools learning to detest mathematics… They return to the elementary school to teach a new generation to detest it.”

Quoted by George Polya in How to Solve It. I finally got my very own copy of this excellent book, so I can quit pestering the librarian to let me order it from library loan again…

Blogger Rudbeckia Hirta teaches math to pre-service teachers, and it seems that not much has changed since 1956. Hirta says the test answers shown were representative of her class — for instance, 25% of her students missed the juice problem. Too bad these students never read Polya’s book, in which he discusses a four-step method for solving problems. Step four is to look back and ask yourself whether the answer makes sense. Good advice!

Why Study Mathematics?

[Rescued from my old blog.]

What teacher hasn’t heard a student complain, “When am I ever going to have to use this?” Didn’t most of us ask it ourselves, once upon a time? And unless we choose a math-intensive career like engineering, the truth is that after we leave school, most of us will never again use most of the math we learned. But if math beyond arithmetic isn’t all that useful, then what’s the point?

If you or your student is singing the Higher Math Blues, here are some quotations that may cheer you up — or at least give you the strength of vision to keep on slogging.

We study mathematics…

Math Quotes V: A Man Is Like a Fraction…

[Rescued from my old blog.]

The blackboard quotes for my math class have been a bit more philosophical the last few weeks:

A good problem should be more than a mere exercise; it should be challenging and not too easily solved by the student, and it should require some “dreaming” time.

Math Quotes III: Five out of Four People

[Rescued from my old blog.]

I’ve been procrastinating my preparations for co-op classes this week, but I think I’m ready. I almost forgot the scissors, but now I have them in my bag, so we will be able to cut the “infinite pizza” pieces. And I have two fun quotes for the blackboard:

Math Quotes II: The Ultimate Goal of Mathematics

[Rescued from my old blog.]

I thought you might enjoy the quote I’m going to use on the blackboard in math class:

The clearer the teacher makes it, the worse it is for you. You must work things out for yourself and make the ideas your own.

—William F. Osgood, quoted in
Out of the Mouths of Mathematicians

I’m Ba-a-a-ack! (Math Quotes of the Week I)

[Rescued from my old blog.]

My computer and I seem to have come to a temporary truce: I pretend I’m never going to shut it off again, and it pretends it’s always going to come back if I do have to reboot. (Nope, no new computer in the offing at this point. We’re just at a cease fire here, until the next big thunderstorm throws a power outage at us…) So I thought it was high time for me to get back into the habit of blog posting.

Math Humor, and Some Copywork Resources

[Rescued from my old blog.]

I have been reading up on Charlotte Mason’s teaching style, and I plan to incorporate more copywork and dictation into our school program next year. Here are a few of my favorite funny quotes about math. (These would also make great blackboard quotes for a math classroom.)
