Welcome to !
I opted for a second career in school education after a 17-year corporate career in India and Nigeria. After a 24-year career as a Principal and math educator in several schools around India, I retired in 2013. During my career in schools, I had the opportunity to relearn primary mathematics from the math educator the late Shri P K Srinivasan.

He made me realise that though I could “do” mathematics, there were many concepts that I did not know, even in K-8 mathematics. My learning association with him lasted more than 15 years. During that time and till 2015, I conducted more than 50 teacher training programs “Understanding Primary Math for Effective Teaching”. These programs were welcomed by many teachers.

After my retirement, I decided to write down my understandings of K-8 mathematics as a book. The work got completed in 2020. The entire book has come to 268 chapters divided into 32 sections. Each section is about a specific topic area. Each chapter is only 1 or 2 pages long. The details of how I came to write this book, are available in the first section “Introduction & Background”.

I also wanted these ideas to be available easily to any teacher who may want to read and try them in their classes. That is the genesis of this website.

I sincerely thank Sridhar Rajagopalan of Educational Initiatives (EI) for designing this website and uploading the files, in the midst of his several professional responsibilities.
