A casual query came to mind regarding the approach that is being followed for mathematics curriculum that is being developed by HBCSE for primary and middle school level. I am aware that the Small Science Curriculum is based on the inquiry based approach, and similarly I thought of understanding the approach for mathematics curriculum.
According to the group, that is involved in developing the mathematics curriculum, it is based on the structure and connections based approach. A mathematical structure is applied while developing the content which takes care of the conceptual understanding and the necessary prerequisites; and the connections are made of the content while deciding its long term effect as to why a concept is important in primary level and what is its significance in the middle school level.
the above points are based on the discussion over tea table (Subramaniam, myself)
