    Questions presented in the worksheets look simple but are confusion. One actually needs to calculate to be confident about the answer. But it's always good to be in touch of Mathematics and solve sums and puzzles also.

      They seem to be confusing due to lack of conceptual clarity. With regular reading, solving, concepts become clear

Mathematics and Life 2 About me - Early Childhood to formating years

Being a government doctor with zero PR activities, I continue the trend, transfer or long posting in tribal areas was a norm. We spent 6 years in Bastar district in early 1970s. One of the most interesting things to recall is we three brothers often used to sit and talk a lot in Hindi. In the presence of parents, we three used to interchangeably toggle Hindi - Marathi.

Moving to Indore To reduce the stressful impact of transfers on our studies, in 1976 myself and elder bro...

  The importance of definition  I would like to discuss how the policy makers', parent body, school administrators, investors', teachers' perception of what is it to be good at maths ? affects the students and ultimately the workforce, industry, economy in general. 1. Mathematics as a computational tool    This is the current, popular perception of knowing maths. Our classroom teachings, examination system, wide spread tutoring, coaching business all tend to develop, appreciate, the skill of reaching one unique answer as fast as possible. The Abacus or its various versions, as a training tool are classic examples of this. Students are expected to be too good at a skill in past 61 years of life I have not needed. I ask the readers, how often, if at all, you needed to find 5813 x 3876 infraction of a minute and that too accurately ? I bet never. But, just as a ritual, under peer pressure children go year after year to learn something which is first of all not needed at...
