At Right Angles
This magazine for school mathematics is published in collaboration with Community Mathematics Centre, Rishi Valley.
We started At Right Angles to create material for teachers and children across the country to read about mathematics material that is not found in regular school curricula. This is the space for students and teachers to share original observations and discoveries, where beautiful results in school level mathematics can be written about and discussed.
Our intent
At Right Angles is useful for people with an interest in K‑12 mathematics education, including curriculum developers and teacher educators. The magazine addresses issues which you might face, and we hope you can benefit from learning by sharing. The articles and short pieces are written by mathematics teachers at various levels, with a view to sharing mathematical content as well as real life classroom experiences and teaching strategies.
All materials are freely available, with option to download the whole magazine. The magazine is currently produced in English and the PullOut section is translated into Hindi and Kannada.
Readers of the magazine can interact on several platforms:
- Facebook Pages
AtRiUM (for secondary and higher secondary)
Math Space (for primary and upper primary)
- Webinar — We invite authors and readers for live, online discussions on the third Wednesday of every month.
- Letters to the editor (addressed to AtRiA.editor@apu.edu.in)
- Our Telegram channel https://t.me/APUAtRightAngles

Recent Event | The Art of Mathematics
Bead chains are commonly used for counting, a tape for measurement. Can a single manipulative combine both these functions? And can the whole be more than the sum of its parts? Find out from Sunil Bajaj, SCERT Haryana as he talks to Swati Sircar about SOGOL.
Read the article in English and in Hindi.
