  We picked a time. We're meeting for nine weeks, each Saturday from March 2 to April 27, for an hour, at 3pm PT / 6pm ET. We still have a few spots open. We'll be playing with Triangles, Circles, and Pi, along with the fictional Althea and her friends. Participants will get an introduction to geometry, proof, and trigonometry.   I'm writing a new book series, Althea's Math Mysteries. In four young adult novels, Althea and her friends explore some of the mysteries of mathematics. The first two books are nearing publication, and the second book needs folks to test it out.

  Join an online math circle for students ages 12 to 15 in March and April, exploring geometry, proof, and the basics of trigonometry.   As most of you know, I'm writing a new book series. In four young adult novels, Althea and her friends will be exploring some of the mysteries of mathematics. The first two books are nearing publication at Natural Math. In Althea and the Mysteries of Triangles, Circles, and Pi, Althea and friends, with the help of Althea’s mom, explore geometry and proof in order to then learn the basics of trigonometry. My publisher and I would like to find some ea ..read more

The Storytellers of Math

1M ago
Anyone here reading knows that I'm working on my series of young adult novels with math at the center - Althea's Math Mysteries.   But did you know that this drive to tell math stories is growing among budding storytellers across the lands?  Sue in California (me!) is writing Althea's Math Mysteries. Four of them! Shayla (aka SK Bennett) in New Mexico is writing the next book after Marco the Great and the History of Numberville. And Sarah Allen in Washington has written some wonderful fairy tales about physics and math. I'm reading Newton's Laws: A Fairy Tale right now.  (Curren ..read more

Illustrating Althea
Math Mama Writes
by Sue VanHattum
3M ago
I'm not much good at drawing, but most of the illustrations in Althea and the Mysteries of Triangles, Circles, and Pi are math work. I can do those. So I've put my own illustrations into the manuscript as placeholders. There will be a professional illustrator, later. This past week, I was looking for where more illustrations are needed. I decided Althea would draw a map of California while thinking about their summer trips. So I drew it. Their home is in Berkeley, they go to camp in Quincy, and they're planning a trip to San Diego to visit Legoland (because her younger brother Rudy would love ..read more

  This blog may not be as active as it used to be, but it's a good way for me to remember some things. My first post about my Althea stories was in September of 2019, so I've been working on the first two books in this series for four years now. I'm hoping we'll be able to publish them in about a year.  I have a very hopeful timeline that puts publication in October. But we all know that things never go as well as we hope. (And I'm wishing we could do it just a bit faster than that, so they'd come out in time for Math Storytelling Day, September 25, Maria's and my birthday.) I have ..read more

Playful Math Blog Carnival #166

8M ago
This blog carnival has been around for 14 years. Almost every month for 14 years, someone has added a post to this collection. That's quite a long life for an internet phenomenon. (Congratulations, Denise, for keeping this going!) If you'd like to see any of the previous posts in this series, check them out here. For many years, blogs were a big part of my time online. But not so much lately. When our number (166 now) was in the 20s, 30s, or 40s, I'd make sure to have that many links. Nope, I don't have time to find 166 great links (and you'd get tired just looking through them). But they're o ..read more

Althea's Math Mysteries

 I've been working for a few years on Althea and the Mystery of the Imaginary Numbers. It's almost ready for the illustrator. But I wanted to dive deeper into the characters, and started working on the second book in the series, Althea and the Mysteries of Pi. I'm about 80 pages in on my first (very rough) draft. It has been a blast writing this, because I pretty much know where I'm headed. (Although sometimes I worry that there's too much math, and not enough character development. And then I back up and think about Althea, Kiara, Sofia, and Aiden some more.) Today I wanted a good place ..read more

Prepping for Fall, Calc II: Lovely Arc Length Example
Math Mama Writes
by Sue VanHattum
1y ago
I'll be teaching Calc II for the first time in a few years. This is my first time starting out online with it. So I'm preparing my Canvas shell and thinking about how I want to explain each topic in Canvas. (I know the material well enough that I didn't have to prep this much when we were in person.) The extra prep before we start feels like so much work, but today it feels totally worthwhile.     For arc length I was excited to use "crinkle crankle walls" as an example. Isn't that a pretty wall? And you can actually use fewer bricks this way than for a straight wall, because one ..read more

Technology Woes and Cheers: Venn diagram edition
Math Mama Writes
by Sue VanHattum

I'm writing questions for my Discrete Math course that will be available to my students (and others) through MyOpenMath, a free online homework system. I'm not very good at programming in their environment, but I'm learning. The cool thing about MyOpenMath is that it uses random numbers in the questions so that each student might get a (slightly) different question. I wanted a way to ask, for a random Venn diagram: What is the set notation for this? First, I needed a way to make lots of Venn diagrams, all pretty, and all in the same style. I searched the internet for a free online Venn diagram ..read more
