Classical Mathematics ONE

Classical Math ONE Bookcover

Primary Sources

We’ve developed Classical Mathematics ONE to provide parents and students with a classical ad fontes alternative to modern geometry textbooks. The curriculum guides students through 5 books of Euclid’s Elements (I-III, V-VI). The vast majority of time is spent with Euclid, although two other texts are introduced to provide background, context, and perspective. The curriculum is organized and arranged to first disorient students away from their preconceptions regarding mathematics. Next, students are immersed in a beautiful world of numbers to allow them a sense of the aesthetics of math. After those preparatory experiences, students are introduced to Euclid and learn to follow and create proofs, perform complex constructions, and think critically about the nature of geometry. In short, students will learn to think like mathematicians rather than mere computers.

Student Journal

Classical Mathematics ONE, like a good teacher, is a guide to great texts; it does not presume to replace them. Thus, it intentionally lacks many of the helps that textbooks provide. It presents no pre-packaged formulas to memorize or step-by-step commentaries. Instead, it gives students a framework within which to make these great texts their own. Students are guided through the creation of a math journal. Students record their questions and observations in their journal, along with their efforts to solve problems. This way, students will gain mastery over the material by writing their own textbook filled with their own questions, solutions, and insights.

Teacher Guide

This detailed PDF guidebook includes commentaries on daily lessons and readings, construction guides, and answers to the study questions and proof problems.

As of the last update (26 Nov 2022), the Teacher Guide covers the first 27 cycles (out of 31) of the student guidebook and all of the proof problems for the year. (Check back weekly, as updates are pushed every Thursday. Feedback is welcome and encouraged!) 

The Teacher Guide is available for free as a PDF download.

Video Lessons

The curriculum includes unlimited access to weekly instructional videos. Each week has only 4 days of assignments to give time for the video lessons on the 5th day. The videos include lectures and detailed walk-throughs of the propositions and problems the students tackled during the week. The videos will also provide detailed solutions to the week’s exercises. Students will be able to grade and correct their own work at the end of each week as they watch.

The entire video sequence can be viewed here.

Reviews & Testimonials

  • “I’m excited about this course and highly recommend it to anyone seeking a manageable way to study and teach Euclid’s Elements either instead of, or alongside, modern geometry curricula.” – Kristi (See Kristi’s full review HERE.)


  • “I am a high school senior student who has taken your Classical Mathematics course as my last math curriculum. […] I thoroughly enjoyed your course, and I have been promoting it for high schoolers.” – Chloe

We’ve worked hard to make our curriculum as affordable as possible. Similar geometry curricula (textbook + exams + videos) typically sell for over $150. Because we’re a small, ministry-minded operation, we’re happy to sell our curriculum for $59.99. That’s a $150+ value for less than $60. 

Classical Mathematics ONE is also available as a live class!
