Abstract

In our weekly Ganit Manthan class, we do mathematical explorations with school students. I posed a problem on probability to the students who knew only elementary aspects in probability and were not formally introduced to the subject. The question was as follows: You are talking on the phone with your friend who is a boy. He asks you this question: “I have a sibling. Can you put a guess whether my sibling is a girl or a boy?" If you were to place a bet on the gender of the sibling, what would you place a bet on - a boy or a girl? This article is the experience written in the voice of three students on how they went about solving this problem using empirical data collection. I hope that Mathematics teachers can draw ideas from this exercise on making Data Collection and Data Handling interesting and engaging using examples that may be relevant for the students. It can also give ideas on how to engage in a discussion on the process of data collection before the data is analyzed. And all this, within the gamut of learning ability of upper primary school students.
