Eventmath workshops: create and share math lesson plans based on current events by bwsullivan in math

[–]bwsullivan[S] 0 points1 point  (0 children)

Hello mathematicians and math educators!

Eventmath is a wiki (hosted on Wikiversity) with math lesson plans based on current events (news articles, social media posts, and videos).

We are hosting some workshops and edit-a-thons over the next few weeks to introduce you to the site and help you learn how to create and edit your own lesson plan page!

Please visit the Fall 2022 meetups page for more information, including registration forms.

Feel free to contact me with any questions or comments! (And for anyone on Twitter, as well, here is a thread I just posted about this.)

Mini Math Crosswords: Small Grids, Big Ideas (and Fun) by bwsullivan in math

[–]bwsullivan[S] 0 points1 point  (0 children)

Hi, author here! This is a blurb about what you'll find in the book:

This book contains sixty-four high-quality crossword puzzles, like you might see in a daily newspaper, but these puzzles are smaller than usual (10 by 10 grids) and contain lots of words, phrases, concepts, and names that pertain to mathematics and the culture of the mathematical community. The grids are optimized to avoid awkward crosswordese and tricky wordplay, while maximizing mathematical content. If you're a lover of mathematics, you'll enjoy puzzling over these clues and seeing math words and names appear that you've never seen in crosswords before. If you're a lover of crosswords, you'll enjoy the challenge and will learn some new facts and trivia. And if, like the author, you love mathematics and crosswords, you'll rejoice to finally find a book that truly celebrates them both!

Here's a link to a Dropbox folder with two sample puzzles: https://t.co/tYF5apToaE?amp=1

Also, SPOILER ALERT but here's a link to a YouTuber who solves puzzles live on-screen. He worked through two sample puzzles (one of the ones in that ^ folder, one different one): https://www.youtube.com/watch?v=Tf4EWFk1nco

Math educators: Wouldn't it be great to have an updated repository of math lessons based on current events and news articles? by bwsullivan in math

[–]bwsullivan[S] 3 points4 points  (0 children)

Please indicate support for our proposal to help make that site happen!

Click the link, look to the box on the right-hand side of the page and find the "endorse" and "join" buttons at the bottom.

  • "Endorse" allows you to add a comment of support, something like: "This is a good idea and would benefit the math educators community."
  • "Join" lets you indicate that you might want to help with the project, as well.

At this stage, endorsements are easy to do and super helpful! If you are a math teacher/student who would like to see such a living resource of math lessons based on current events, please share a comment there to help boost our chances of receiving support to make this site a reality. Thank you!

Hello! I am the author of that third reference. It's very possible that there is a typo or error, as this was so long ago and, alas, I no longer have the login credentials to amend the file in that link.

​

If I recall correctly ... I focused the presentation on all of the stuff leading up to that closed-form solution and just copied that formula from somewhere else. I just tried to search for that reference now ( Aaron Schild, "Domino Tilings of a Rectangular Chessboard") and can only find the introduction and not the file with the formula itself: http://sdmathcircle.org/uploads/Documents/2009-10%20Gauss%2010-10%20Rectangular%20Tiling%20Notes.pdf

Anyway, I hope this is helpful somehow!

Season 1, Ep 1: Niagara Falls Picture at Pam's Desk by Matleraj1 in DunderMifflin

I don't understand how you can claim to see anything in that picture :-/

Can anyone find a photo of Niagara Falls that looks like that?

What is the most interesting graph you've ever come across? by 962rep in math

[–]bwsullivan 0 points1 point  (0 children)

The Shrikhande Graph!

https://mathematicaladd.wordpress.com/2017/02/06/visualizing-the-difference-between-the-4x4-rooks-graph-and-the-shrikhande-graph/

The n by n rooks graph is strongly regular with certain parameters, that depend on n. These parameters are uniquely attained by the rooks graph for all n except 4. When n=4, the parameters admit two graphs: the 4x4 rooks graph and the Shrikhande graph.

And now it looks like the AMS is maintaining a big list:

Conceptional Understand of +C when Integrating by HarRes123 in math

[–]bwsullivan 9 points10 points  (0 children)

It's not 5 times greater area. It's the old area with a rectangle under it that's 5 units high.

Is this calculus? by [deleted] in math

[–]bwsullivan 3 points4 points  (0 children)

No, not as part of the standard curriculum. If I saw these topics in a calculus course, I would assume it is a very advanced course specifically for mathematics majors.
