Openings Now in Free Online Math Circle


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 eager math students to join me in an online math circle, exploring some math mysteries along with Althea and her friends. Participants will join lively small-group sessions: in part a deep and friendly math course, and also a unique book club, allowing me to refine the story based on student reactions.

Althea and the Mysteries of Triangles, Circles, and Pi is a fictional story set in the present, in which the characters discuss math, with Mom throwing in a few true stories from the past. Like The Number Devil and Math Girls, this book gives you more the more you put into it by doing the math yourself.

Do you know any students who enjoy math, know a bit of algebra, and would enjoy user testing Althea and the Mysteries of Triangles, Circles, and Pi? We’re looking for 5 to 8 young people to try out the activities in this book together. If interested, please add your name and information here.



  • Attend 9 weeks of 60-minute live online sessions in March and April. Times to be determined, most likely 4 p.m. EST / 1 p.m. PST, on Saturday or a weekday (whichever works for more students).
  • Read and comment on 1 to 3 chapters of the book each week.
  • Keep an informal math journal during this time.


For all who stay the course:

  • You’ll learn the foundations of geometry and trigonometry (and will get a certificate for completing the course).
  • You’ll get a signed copy of the published book.
  • Your name or alias will appear in the book’s acknowledgements, and you will receive a letter of appreciation for your help with this STEM project. (If you’d like a letter of recommendation later, we will be happy to write one for you.)
  • You’ll get to build community with math friends and mentors.

  1. Sadly, we're away traveling during March and most of April, but really interested in your new books! I have a 12 year old daughter who used to love maths, but is currently burnt out and really hates anything traditional maths looking! When do you think these will be available? Best wishes, Rhiannon

  2. Hi Rhiannon, I am hoping for end of this year, but it is likely to take a bit longer. If your daughter would like to beta read the text individually, email me at mathanthologyeditor on gmail.
