MoMath founder, on math’s image problem…

Glen Whitney, founder of MoMath, makes interesting comments on the image issue common in Mathematics education today (article source from Smartplanet);

And you’re the only math museum in North America.

That’s correct.

Sounds like Germany really likes math.

Well, there’s a very distinguished history of mathematics there. It’s likely that the museums are a reflection of the cultural stance on mathematics there. There are also math museums in South Korea, Italy, Spain, Japan, Budapest, and one is forming in Brazil.

You said earlier that math is misunderstood in the U.S. How so?

In the roughly 2,000 hours of math instruction you get in traditional K-12 school, you get a non-representative view of what mathematics as a human enterprise is like. You learn that every problem has a specific method, and it’s just a matter of matching up the problem to the method. If you follow that recipe, you will get the one correct answer. There’s no sense of creativity or imagination or beauty or exploration. I think exploration is at the core of what mathematics is as an enterprise.

There’s also this impression that math is utterly linear. If you reach an obstacle — whether it’s something you find difficult or just don’t like — under the linear model of math, you’re done. You can’t proceed. Math must not be for you. That image is wrong. Mathematics is actually extremely bushy. There are so many different areas, and there’s no need for people to feel that if they don’t like one area, then they don’t like math at all.

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
