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 under the theme “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 roughly following the K-8 math curriculum. 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.

In these articles, readers would find explanations of concepts underlying different types of numbers, geometrical shapes and various other topics. Generally, they would not find explanation of computational procedures or algorithms unless these are used as examples to explain underlying concepts. There are at least two ways to access the content. A quick way is to search for words & phrases through the Search Panel. The other way is to browse the Topic Index.

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.
