Mathematics Professor, Annaswamy Ranganath Rao is 100 years old and is one of the pioneers in popularizing the concept of Math labs in schools. The Central Board of Secondary Education (CBSE), recognized this method of teaching mathematics and made it mandatory to have Math labs in CBSE schools. Since 2006, this concept has been introduced with 80 marks from theory paper and 20 marks from the activities conducted in the Math lab.
Professor Rao introduced Math labs way back in 1974, making it easy for students to understand various Math theorems. He designed new models, gadgets to explain these concepts to students, making these concepts more understandable and at the same time a playful experience too.
