Enjoying these daily Fermi questions! I hope this site keeps it up. Definitely would share with students.

August is here and so is the Calendar of Problems!
Back to school is soon (or now) so do some #ProblemSolving yourself or w/students.
Share your thinking here or on the post.

Incredibly proud of our mathematical modeling team who placed in the top ten worldwide in the 2025 International Mathematical Modeling Contest (IMMC)! Unfortunately our team couldn't make it to Hong Kong last week for the IMMC Summit and awards presentation. Maybe next year!
Proud to be profiled on the COMAP website! This article highlights the incredible work done by the students in our applied math and modeling group this past year. They achieved some great things, and we're looking forward to more modeling next year!
Came across Seymour Papert's "Teaching Children Thinking" essay:
https://citejournal.org/volume-5/issue-3-05/seminal-articles/teaching-children-thinking]
(thanks @ColinTheMathmo for the better link)
It captures almost exactly my philosophy of education, teaching, computing, and so on.
I want to quote so much of it! Here's just one:
"The purpose of this essay is to present a grander vision of an educational system in watch technology is used not in the form of
machines for processing children but as something the child himself will learn to manipulate, to extend, to apply to projects, thereby gaining a greater and more articulate mastery of the world, a sense of the power
of applied knowledge and a self-confidently realistic image of himself as an intellectual agent."
I'm surprised at how the article -- from 1971! -- describes so many of the programming-like things available today. So much of the play-oriented things we have now -- games like Robot Turtles, various robots that do path-following things -- are exactly what they were doing over half a century ago.
Here's a real context #geometry question on area & volume.
Home Depot changed the size of their heavy duty small box from last year to this year.
What has been gained/lost? Why do you think so?
Old box: 11" x 17" x 11"
New box: 12" x 10" x 16"
Summer is here! What are my #iTeachMath #MTBoS #MathsToday friends going to do?
This post is several years old but the message is still fresh:
-Read a book
-Learn something new
-Make a plan (to revise, refresh, renew)

We've had some incredible results in our mathematical modeling program this year, The latest: A team of three of our high school students won the Mathematical Association of America award for their submission to the university-level Mathematical Contest in Modeling run by COMAP! They were one of 18 teams out of 12,000 worldwide to earn an "Outstanding" designation for their mathematical projection of Olympic medal counts for the 2028 games.

Had to step in and remediate two faulty questions on my son's #Geometry homework tonight. Note to the "Teachers Pay Teachers" worksheet author: A regular octagon does not have 4 lines of symmetry.
Note: Thanks to @danielmclaury for pointing out I should have specified that it was a regular octagon on the homework handout.
Today's #geometry problem from May calendar is 1 of a few related problems (I like how this month has several sets that relate to/build on each other)
Tell us how you thought about it; check out whole calendar @ link above.
Just got my author copies of Python for Mathematics! (https://www.routledge.com/Python-for-Mathematics/Knight/p/book/9781032582184)
The book flips the usual programming order—starting with powerful maths tools before diving into code.
The publishers worked with me to agree to keep an online version available too: https://vknight.org/pfm/cover.html (This version needs updating!)
You can find some of my thoughts on how the book is structured here: https://vknight.org/2025/05/19/python-for-mathematics-book.html
More updates soon.

The May 8 problem is one of a few this month involving "petals" created by overlapping arcs of circles.
Try this fun #geometry problem & tell us how you thought about it.

I know I've done a good job as a teacher *and* as an assessment designer when students correctly answer test questions in multiple ways I had not anticipated.
The May Calendar of Problems is here! Enjoy some #Math #ProblemSolving in the home stretch of your school year!
Plus Bonus Article "Table Techniques" using table of values as dynamic tool w/technology.
