I posted it to the *other site* when it came up in class last year. I meant to take the problem out this year but it led to come good discussions!
This problem came up in #MathsToday and it is more delicate that it may initially seem.
"For what values of k does k*sin^2(x) + sin(x) + 1 = 0 have solutions?" What would you do?
Thank you!!
🥰🥰
awesome, thank you!
Great suggestion - thank you!!
I love this!

Oooooh, what sorts of things does it say?
Better yet - show us! 😊
High school math teachers, what do you put up on the walls in your classroom and why? What's the first thing you'd put up in a new classroom? Looking for ideas! I have lots of whiteboards already and lots of unused space...

Not sure if the #playwithyourmath team are "here". I can't wait to try out the newest post, Jump Step, playwithyourmath.com/2024/12/01/3... #iteachmath #imentormathed #MTBoS
A poster outlining three steps (specialising, conjecturing and generalising) to enhance mathematical thinking. The poster uses the classic "how many squares on a chessboard?" problem to exemplify each step in the process.
Specialise, Conjecture and Generalise.
A three-step plan to encourage and develop mathematical thinking when faced with an unfamiliar problem.
Folks in 🇨🇦 and elsewhere… the Ontario Assoc for Math Ed (OAME) conference has become the SPOT for great #ITeachMath pedagogy. Consider proposing a session for May 2025!
What’s that idea you’ve been working on? Throw it in!
Six circles, each partially shaded in a different way.
What fraction of each circle is shaded?
(The 12 points on the circumference are equally spaced, and the other dot is the centre)
I’d love to see how you solved it!

pairing of etymology of math calculus and Newton (who helped invent calculus) quotation in which "pebble" appears in both
today's NYT connections reminded me of two pebble mentions as relates to calculus:
1) etymology of calculus (the mathematical ♾️ type)
2) a quotation from Newton, one of the big names in early calculus, about how he saw himself

April 25: Find the sum of all twenty-four different permutations of the number 1234
April 3: A circle is inscribed in a square whose side is 10. A second smaller circle is drawn tangent to the first circle and tangent to two sides of the square. Find the diameter of the smaller circle.
April 12: If f(x) = x^2 + bx + c, f(1) = 9, and f(3) - f(2) = 8, Find f(4)
Today is a good day for #ProblemSolving !
Here are 3 nice ones from the April Calendar of Problems; try them out & share your ideas.

The 2nd episode is a great listen if you want to get a little existential - which is fitting, since it is about zero.
I love Radiolab because an episode about dividing by zero is really about finding meaning in existence.

The last 2 episodes of Radiolab are some of my favourites.
They're about math, but the parts of math I like best: the human experience of doing math, the way people use math as a kind of refuge from the world & also how people build community around it.

This has big *tap tap is this thing on* energy BUT the math department at The York School is hosting the 2024 ISOMA Conference on Jan 11, 2024. Please share with any Ontario Independent school math teachers you know! Registration is open until Thurs, Dec 21st. drive.google.com/file/d/1XiTu...
