Were you searching for something?

May 29, 2006 pm31 1:03 pm

Math-jd-in-Kansas spent three whole posts answering the questions implied by the searches crawlers used to find him, and shouldn't we all do that every once in a while? Now, I don't have so many hits to choose from, but there's some. So here's my go at it:

Teaching

1. memorizing formulas mathematics value. It is incredibly important to memorize formulas. Only, I think when teaching it is best not to lead with the formulas. Once I delayed π for over a week. Kids were estimating circumferences with "a little more than 3 times the diameter." Believe me, when I finally gave them π, it held, and made more sense than if they had got it the first day.

2. Lots of deal/no deal stuff. Folks, there is no formula for winning. You get picked? You've already won. Only question is how much. I'll address a little of the math here, probably this week, but if you are researching strategy you are probably too clever for Howie Mandell to want you. Better to jump up and down on a street corner saying "I'm feeling 19" (use a different phrase for lower numbers. Just trust me on that). (I will also discuss ro?uxxxllxxxet?te. But I will take steps to keep that word out of the search engines. I couldn't bear that traffic).

3. Teaching Rationalizing Denominators. Got a few of these. They seemed to want the history, not the pedagogy. And I am not certain. I think, though, in pencil and paper days, that recalculating a quotient with greater accuracy would have been straightforward with a rational denominator, but require a complete repetition of previous work with an irrational denominator.

4. Blog > Inappropriate Dress. Only one hit on this controversial topic (surprises me, I can't find the phrase anywhere on this blog). Anyway, I'll write about this. Soon. Promise.

Puzzles

5. I recently got "sum of the first 100 even counting numbers." Now, I have a definite feeling about this. List out the first few (few = 10 today?) even counting numbers. List out the first few regular counting numbers. Compare the lists. Compare their sums. That should have you on your way.

6. Largest 3 digit number with 10 factors. Nice little puzzle. I am going to leave that one for others to have a go at.

7. Recently I got a few hits that looked like: "how to get 24 from 3 8," or "math puzzle 8 8 3 3." So they came to jd2718 to get a solution to a 24 puzzle? No problem. In the game '24' you get 4 numbers and have to combine them with the four basic operations (+, -, *, /) to arrive at a result of 24. All four numbers must be used.
Btw, 2718? 2*8 + 7 + 1, in case you were wondering.
So, for 8833 you need a first step. If it involves both 8s we have 0 3 3 or 1 3 3 or 3 3 16 or 3 3 64. By inspection none of these yields a solution. If the first step involves the 3's: 0 8 8 or 1 8 8 or 6 8 8 or 8 8 9. Again, no dice. Finally, by combining a 3 and an 8: 3 5 8, or 3 8 11, or 3 8 24. Hey, maybe I missed something, but it sure looks like none of these pan out. You've got yourself there a no solution. Feel free to jump in.

Union

8. Some UFT searches, such as uft & chapter leaders and UFT contract and What is UFT delegate can be answered at the UFT website. Here are the contracts.

9. "NYC pay rate for working summer" You get paid per session (currently $37.96/hour). Your gross pay, if you do in fact work summer school, will depend on the hours of the program you are hired for. If you work 5 hours a day in a 4 day a week program for 6 weeks, that's 120 hours or about $4555. If you are working a high school program, check early on if you will be proctoring and grading regents. And at the end they should be adding some time to your Cumulative Absence Reserve (CAR).

10. a bunch of you want to cash in on the DoE's housing incentives. (remember I was opposed to them. But now they are here, we help people collect money to which they are entitled). Others wanted to know about incentives in general. The recruitment pages at the Department of Education's website has some of what you are looking for. For housing they give: "Contact: David M. Cantor / Keith Kalb (212) 374-5141" on the press release page. They also have other incentives.

Searched, Found

11. Most of your searches were dead on. You came here, you probably found what you were looking for. A few examples: 0 through 9, 4 digit number; examples work nyc classroom; pythagorean triplet + puzzle; empowerment schools NYC; and so on. Some union, lots of puzzles, lots of teaching.

12. Math cemetery. How do you answer that one?
"There's where they buried e. I thought he'd go on forever. "
