(Mathhombre) Miscellanea
Measurement problem.
It was a pretty good problem on the front end, too. Smallest table size was 58”, longest 106”, and the table cloths we were interested in covering went from 70” to 108”.
What other questions could you ask with these images?

Story Problem.

You know that meme: warned by your math teacher? I had one of those experiences today.

We live in West Michigan and it is blueberry season. We live amongst many blueberry farms, and love the berries from Behm’s. We did U-pick this year with our friend Heather, who picked blueberries for a job as a youth. Karen and I are both novices, and Karen is a perfectionist. Heather filled her bucket, then starting helping Karen when her bucket was 2/3 full. When they were done, they both helped John finish when his bucket was 5/6 full. (3/4 if you trust the doubters.)

Other info: we picked about an hour, 8 lb.s of blueberries can fit into a bucket, and $11 for a bucket no matter how heaping (so you fill to heaping). Chuy, a young migrant picker we know, talks about picking 150 lb.s a day as a minimum.

What can you figure out?

Pizza Price Per Inch^2
NPR’s Planet Money did quite an extensive survey of pizza price per size. What function best fits the resulting graph? Why?
The graph on the Planet Money site is interactive, and has factoids like: “One 16-inch pizza has roughly the same area as 1.3 14-inch pizzas or 4 8-inch pizzas.

To get the same amount of pizza you get in a 16-inch pizza, you’d have to spend an extra $2.35 on 14-inch pizzas, or an extra $16.41 on 8-inch pizzas.”

Fun little nothing.

Occasionally, I’ll stumble across theuselessweb.com, which is exactly as advertised, and provides perfect nonexamples of creativity a la Ken Robinson. These are original ideas without value.

For the most part. Last night it took me back to Koalas to the Max, with which I made the images above. It divides one circle into four half size circles. Loads of mathematical questions come to mind… so decided to share it.

Despite the fact that it reveals that I will click on “Send me to a useless site, please.”

A baker friend proposed this challenge today. And for some reason I am convinced it is perfect for a Math Rage Comic. What do you think? Does it suggest the question strongly enough? (My kids say no.) I made about half of it using the rage builder.

This is over on 101qs.com. Please go there and ask your questions.

UPDATE: the actual cake from the problem.

Spontaneous #anyqs. Karen and Gail wondered: how many cupcakes do we need?

Meat Math! #anyqs?

BTW, the kielbasa was delicious. Bake at 350 with enough water to not evaporate (~2 c), seasoning if you want (for me, bay leaf, pepper). Remove, simmer in beer (stout is my preference) in the pan or a crock pot.

Humble Bundle Math

There’s a great music humble bundle on right now. (Sometimes it’s software, or games.) You pick a donation amount, and then split up the money amongst the authors/musicians, the charities, and the humble bundle folks.

But I love how the divvy applet works. Raises some nice algebraic questions for me.

How about you? #anyqs?

Oh! I was just plying with lemniscates yesterday in GeoGebra. (x^2+y^2)^2=2c^2(x^2-y^2) is very interesting.
Could students watch this and see the geometric property being referenced?

Tale of Two Hot Dogs #anyqs

Something about this situation made my mathey-sense tingle and compulsed me to buy and cook these two not quite similar hot dogs. Any questions? (At 101qs.com)
