Popcorn #Anyqs

Our terrific local movie theatre, Cinema Carousel, has a popcorn deal where you can buy a bucket and get 2 refills per visit for about half a year. We love movies and popcorn, so we have been buying these identically sized buckets for years. Like the winter bucket:

But when we went to the Avengers-

(It was AWESOME.
Down, inner fanboy, down!)

-there was a new, visibly smaller bucket.

The ticket seller said, “oh they just look smaller.” It’s like he knew I was a math teacher and would now have to buy it.



What do you think? Can you tell from projection/cross sectional area? Is it obvious? What matters more, width or height?

For those who need to measure. Do you need to measure?

Average Score #ANYQS

One of the great things about Drop7 (others - puzzley problem solving, it is free!) is that it gives excellent data. I thought it was cool that my average budged so little after these two games, but… any questions?

BTW, I’m stuck with a max score in the high 300Ks. If you have any tips…

Cookies #AnyQs

So, what do you think?

Perhaps the most fun aspect of this was trying to explain why I was taking the picture.

Sweet Potato Crusted Quiche

Love these #anyqs moments. Karen is making an amazing sounding asparagus bacon quiche with sweet potato crust for her bible group, and she says to get out the rectangular dish. She grated more potato than it called for, and “It must be bigger than the pie plate, right?”

Is it?

"It’s the sides," she says.

Measurements if you wish them:

They are the same depth. I’ll save you a piece if there’s any left over.

Happy Pi Day, everybody!

Toothpaste #Anyqs

Totally tubular. (That’s a joke if you’re over 40.)


Donor Problem

Great graph for problem posing. Maybe too unfocused for how @ddmeyer thinks of #anyqs, but #wcydwt?

From Talking Points Memo via the Daily Dish

I don’t think you can conclude what they are concluding.

Snow Demonstration

I wanted to make this photo an #ANYQS, but wondered if students would be able to see much math in it.

So I thought I’d do it as a think aloud. Coming home early afternoon on Sunday I noticed the shadow of the house lining up with the snow in the yard. Usually we have too much snow to get an effect like this, but it’s been rare this winter. Then I noticed all the houses on our side of the street (south side) had these half-yards of snow, while the houses on the north side had none. What does it mean that the shadow lines up with the snow? That must mean it’s near local noon. Then what can I tell? I ought to be able to tell the high point of the sun in the sky, angle-wise, by using the house and the snow. I didn’t need measurements, because it’s the proportion that matters. Could I tell the latitude I live at from that? Only if I know the date (2/19) or that it’s a special day, like an equinox or some such. Are there online databases of some of this kind of information?

Plus it’s just cool how the snow is in a line - like the border between winter and spring.

Then I found this data, computed from this cool site:

Battery Life

#ANYQS? I was using the computer fairly constantly, except for one few minute conversation.

…Drove to school…

The battery’s a few years old. I was using pretty constantly during the charging also.

Bagel Math

6 teenage girls in the house, I’m sent to Panera. I need 18 bagels - at least - and 2 tubs of cream cheese. This is the menu:

What should I buy? I got the dozen and a half and bought 2 tubs. Is that a right decision? If not, I will defend myself by referring to 6 teenage girls and no coffee yet.

What is Panera’s pricing meant to encourage? There I’m really stumped. Is it good business? How would a mathematician price this?
