Cobsine? Cornsine?

And then gibbets (spelling?) for Crocs?!

Yes, I’m a topological flat earther

I like the topological approach, so yes it is flat even when rolled up.

What are some values for x that aren’t solutions?

I am hoping this reveals something about the direction of their number line, positive on the left ?

Or probability?

Because they use the word percent (pct) I would say they communicated incorrectly.

I’m not aware of any, but would love to hear back too.

Here's the details on the weighting. Those that pay the most, get 6 entries (versus one for the free membership). Oh, and those entries will have much better odds than the free one.

Oh but don't worry, those richest that are able to pay up for the most expensive tier will also get a tax receipt for $4225, so they'll probably only be out of pocket $3000 or so, depending on the province they pay taxes on. In case you were worried about their bottom line.

Lovely! Part of my wondering has led me to the idea of assessing mathematical creativity somehow. Would you ask Ss to do this in an assessment?

The commutative property teaches us that it doesn’t matter who is first, if we work together we achieve greater things.

I see it through problem solving (but a lot of problem solving is not all that creative) and … that’s about it. I do a Desmos project I love, but I see it as creativity using mathematics, not mathematically creativity.

I’ll call it the regularity index, and it will be the decimal representation of the shortest side divided by longest side.

Good to know! I know my students and their post secondary counsellors all feel that calculus is essential for business and science programs as well. A lot of that is legacy I am sure

This! In my area there are so many great courses available at the grade 12 level, including geometry, statistics, and even history of mathematics. Sadly, university programs emphasize Calculus so Ss won’t choose these. Yet for many they would be more interesting and relevant #MTBoS

This graph jumped out at me immediately - the effect is independent of school type #MTBoS
