Math Teachers at Play #5

Welcome to the Math Teachers At Play blog carnival — which is not just for math teachers! If you like to learn new things and play around with ideas, you are sure to find something of interest. Let the mathematical fun begin…

ELEMENTARY CONCEPTS

Hare.
Hare.
They mate.
Now there’s three.
Mate again, now five.
And again, now there’s eight bunnies.
[Now thirteen bunnies, and counting. Mom will be pissed off.]

I suppose you are two fathoms deep in mathematics, and if you are, then God help you. For so am I, only with this difference: I stick fast in the mud at the bottom, and there I shall remain.

Charles Darwin
quoted in the Platonic Realms collection

Any fool can know. The point is to understand.

ADVANCED MATH

A phenomenon that everybody who teaches mathematics has observed: the students always have to be taught what they should have learned in the preceding course… The average student does not really learn to add fractions in an arithmetic class; but by the time he has survived a course in algebra he can add numerical fractions. He does not learn algebra in the algebra course; he learns it in calculus, when he is forced to use it.

  • MIke Croucher presents Simulating Harmonographs, saying, “This is an old one of mine, but it was quite popular — one blog even used one of the resulting patterns as its logo! The equations are relatively simple and should be accessible to any 16+ maths student (or possibly earlier).”

ABOUT TEACHING MATH

Many teachers are concerned about the amount of material they must cover in a course. One cynic suggested a formula: since, he said, students on the average remember only about 40% of what you tell them, the thing to do is to cram into each course 250% of what you hope will stick.

Paul Halmos

  • My entry for this week: Kitten strongly dislikes math when forced to do it on her own, so I’ve started doing Buddy Math with her. I don’t know how it would work in a classroom, but it’s a great method for tutoring or homeschooling.

That rounds up this edition of the Math Teachers at Play carnival. I hope you enjoyed the ride.

The next installment of our carnival will open on Friday, May 1, at I Want to Teach Forever. To contribute, use this handy submission form. Posts must be relevant to students or teachers of preK-12 mathematics. Old posts are welcome, as long as they haven’t been published in past editions of this carnival.

Past posts and future hosts can be found on our blog carnival index page.

We need more volunteers. Classroom teachers, homeschoolers, unschoolers, or anyone who likes to play around with math (even if the only person you “teach” is yourself) — if you would like to take a turn hosting the Math Teachers at Play blog carnival, please speak up!

  1. I like the quotes, especially the one from Albert Einstein! Here’s another good one from him, “Bear in mind that the wonderful things you learn in your schools are the work of many generations. All this is put in your hands as your inheritance in order that you may receive it, honor it, add to it, and one day faithfully hand it on to your children.”

  2. Great job, Denise! You’re setting a very high standard…
    I particularly like those quotes (Halmos’ quote is hysterical).
    Thanks for mentioning the Second MathNotations (Free) Online Contest.

  6. Hi, Michelle & Dave! I’m glad you enjoyed the quotes. I had fun picking them out. Unfortunately, the last line of the Fibonacci quote didn’t quite fit in beside the picture — all 13 syllables were supposed to be on the same line.

  7. Denise,
    Wonderful job… I loved the way you presented the topics…

    sorry I missed out …. sometimes you just have to take a week off and go to France with family… a dirty job, but I’m willing to do it…..

    Will try not to miss the next one…

  8. Welcome back, Pat! I had a couple of your posts bookmarked to add to the carnival, but I ran out of time for editing. Rumor is that the Carnival of Mathematics will be back next Friday, however, and I’m sure the host will be glad to include you.

  9. Wow! I’m surprised (happily surprised) to see my blog post here. I don’t remember submitting that. LOL
    Another great carnival!

  10. If you don’t remember submitting, Jimmie, you probably didn’t. Only about half of the posts here are volunteers. The rest are drawn from my personal blog browsing. I like a full carnival with a balanced variety of topics.

  11. Thank you all for the encouraging words!

    And if any of you would like to speak up for a week as host of the carnival, most of the dates are open. It is a good bit of work to put it all together, but it’s fun, too. (And there’s a benefit to hosting: the carnival provides a traffic boost to your blog, as people come to visit and drop you links!)
