Readers of The Aperiodical are probably familiar with the Carnival of Mathematics, a monthly blog roundup which takes any maths-related content. Did you also know there is a related blog carnival called Math Teachers at Play?
The Math Teachers at Play (MTaP) blog carnival is a monthly collection of tips, tidbits, games, and activities for students and teachers of preschool through pre-college mathematics. We welcome entries from parents, students, teachers, homeschoolers, and just plain folks. If you like to learn new things and play around with ideas, you are sure to find something of interest.
I’ll be hosting the January 2017 edition of MTaP here at Travels in a Mathematical World. Of course, a blog carnival is only as good as its submissions, so if you join me in aspiring to the claim “you are sure to find something of interest” then please keep your eyes open for interesting blog posts and submit them to MTaP. Please submit posts you’ve enjoyed by others or yourself. Posts you wrote that are appropriate to the theme are strongly encouraged. Submit through the MTaP submission form, leave a comment here or tweet me. Thank you!
Submissions are open now, and anything received by Friday 20th January 2017 will be considered for the edition hosted here.
Here’s a selection of news stories about mathematical prizes that have been awarded/announced in the last couple of months.
This year has been frankly ridiculous. And while we’ve done our best to cover all the hot maths topics throughout, we have inevitably missed a few. Here’s some mathematical news bits and bobs from 2016 which we (and you!) may have not noticed.
Aperiodipal numero uno Samuel Hansen’s acclaimed podcast series Relatively Prime is back, on a new monthly schedule, with an episode about how PhD student Ibrahim Sharif designed a lottery to award licences to sell cannabis in the state of Washington.
When the stakes are so high (geddit?! – Ed.) you have to be really sure that your lottery is fair. That’s where a lot of fun maths comes in.
You can listen to Lottery Daze on relprime.com. Sam intends to fund this new incarnation of Relatively Prime through Patreon – you can pledge to pay Sam a certain amount (starting at a dollar) for every episode he releases, with perks for paying more such as a postcard from Sam or placing an ad in one of the episodes.

In this series of posts, Katie investigates simple mathematical concepts using the Google Sheets spreadsheet app on her phone. If you have a simple maths trick, pattern or concept you’d like to see illustrated in this series, please get in touch.
We’re all (hopefully) aware that a pleasing property of numbers that are divisible by nine is that the sum of their digits is also divisible by nine.
It’s actually more well known that this works with multiples of three, and an even more pleasing fact is that the reason three and nine work is because nine is one less than the number base (10), and anything that’s a factor of this will also work – so, in base 13, this should work for multiples of 12, 6, 4, 3 and 2. Proving this is a bit of fun.
Once when I was thinking about this fact, an interesting secondary question occurred.
Puzzlebomb is a monthly puzzle compendium. Issue 60 of Puzzlebomb, for December 2016, can be found here:
Puzzlebomb – Issue 60 – December 2016 (printer-friendly version)
The solutions to Issue 59 will be posted around one month from now.
This will be the last regular monthly Puzzlebomb – in future, there will be occasional one-offs but regular editions are taking a break. If you have any ideas for puzzles, please send them in! Previous issues of Puzzlebomb, and their solutions, can be found at Puzzlebomb.co.uk.
The Association for Women in Mathematics in the USA is running its annual essay contest again, open to students in three age categories from Grade 6 to undergraduate.
Here’s the blurb:
To increase awareness of women’s ongoing contributions to the mathematical sciences, the Association for Women in Mathematics (AWM) and Math for America are co-sponsoring an essay contest for biographies of contemporary women mathematicians and statisticians in academic, industrial, and government careers.
The essays will be based primarily on an interview with a woman currently working in a mathematical sciences career. This contest is open to students in the following categories: Grades 6-8, Grades 9-12, and College Undergraduate. At least one winning submission will be chosen from each category. Winners will receive a prize, and their essays will be published online at the AWM web site. Additionally, a grand prize winner will have his or her submission published in the AWM Newsletter.
The deadline for entries is January the 31st 2017, and if you want the AWM to pair you up with an interviewee, you need to get a request in by January 10th.
All the prize-winning essays from previous years are online, including this nice one about Tanya Khovanova by high school student Emily Jia.
