Featured Courses


Cracker Cacophony

RECOMMENDED FOR BOTH ADULTS AND CHILDREN. We've seen a widespread usage of firecrackers - to celebrate Diwali, on marriages, even at the victory celebration of sport events. The displays look stunning and splendid. But are they affecting us in a harmful way? What about other living beings and their perception of firecrackers? Should we encourage the widespread use of crackers or discourage it? Join this course to discuss and gain a scientific, environmental and social perspective on firecrackers.


Everyday Estimates !!

Recommended Age - 11 years & above.
Estimates are numbers close to the actual number or quantity, like a Guess!! From checking the totals of grocery bills or movie tickets to splitting the cost of lunch between friends or the time you would take to reach your destination...Estimates serve the purpose & make all of this easy & fast. We can quickly arrive at reasonable Estimates of Weight, Distance, Volume, Time, Cost, Earnings etc. Let’s understand Estimates, how to arrive at them & how they help us in everyday life. Let’s get skilled @ Estimation.


Decimals around Us !!

Recommended Age - 11 years & above.
From Counting Numbers for Wholes we move to Fractions for Parts. How about writing them crisply together? Thus, Decimals are born !! Humans are lazy & thus, we keep developing shorter & shorter ways of writing things. 3 apples & another ½ becomes 3•5 !! Let's understand Decimals, these special kinds of fractions, as an extension of the way we write numbers that we see around us on price tags, odometers, weighing scales, calculators etc.


Fractions: A Beginning

Recommended Age - 10 years & above.
We begin counting from 1 and then 2, 3, 4 and so on. But things don't always start with 1 whole. We share parts of 1 sandwich or 1 cake. We have to plan parts of our day or even hours. We know the price of 1 litre milk but may need to buy less than a litre. We may travel distances less than 1 kilometer. Try cooking a recipe without using parts of a spoon or a cup !!
Let's dive within instead of moving onward from 1 whole. Let's understand how we build, write & play with equal parts of a whole, known as Fractions.
