Children are taught many kinds of measures in the primary grades, like length, weight, volume, money, time and finally area and perimeter (which is nothing but measurement of length). While for teaching length, weight and volume, efforts are made to give students an exposure to informal/ non-standard units of measurement (and thus some implicit understanding of what we may use to measure something), the other measurement ideas start with the standard units, conversions and formulae.

A Maverick Mathematician

In these strange and troubled times, when the world is reeling under an infectious disease and a quarter million have died from Covid-19 (as of May 1, 2020), it is perhaps inappropriate to mourn the death of a single individual who died of complications caused by the coronavirus. However, for the world of mathematics, this individual was very special indeed. John Conway stood out among the community of mathematicians, a legend in his lifetime.

A child’s mind is like that of a butterfly in the garden which gets attracted to flowers of different hues and their enchanting fragrance. Children minutely observe happenings and activities in their surroundings and react to the smallest of change. They try to understand an activity or change on the basis of their perception and prior knowledge and develop their ideas. From here, begins the role of a teacher.

Butterflies have always been a source of beauty and wonder. But, what gives these lovely insects their attractive colours? What is the best time to watch them? What do we know about their behaviour? In this article, the author explores the fascinating world of butterflies, sharing some ideas to bring them to life in the science classroom.
