## Learning Social Science – What is Right and Wrong?

## What is a boy? What is a girl? By Kamla Bhasin

Kamla Bhasin's haunting reminders on gender stereotyping are as relevant as ever. Here is the 1st one. You may use it as a 'seed idea' & explore discussions & debate with your learners. You may ask them to build a skit or paint a picture on the same theme.

## Congruence and Constructibility in triangles

Expose your learners to 'degenerate' triangles.

## INEQUALITY FOR THE AREA OF A QUADRILATERAL

Here is an elegant and remarkably compact one-line proof for an inequality relating to the area of a quadrilateral.

## Can Improved Urban Education cause an unintended harm to the nation?

Let me start with a big disclaimer – I am NO expert in the field of “Education”, “Policy”, “Governance”, “Socio-political behaviors” or “Political Science”. I also confess I am perhaps least qualified to even subtly comment on such topics, leave aside writing a post. And yet – I think I should. Perhaps write simply to share a “layman-ordinary” citizen’s thoughts on these topics.

The worst ever nightmare a child (particularly, a girl child) can have is the stereotypical notion of what they can or can't do. Unless there is an active intervention from the very beginning by teachers & parents, the fears and self-doubts persist.

Here is a stinging satire on what boys and girls do. Note: the illustrator is NOT confirming the text he wrote. He is expecting the participant to question and engage the text. Teacher can play it and then start a discussion around it.

## Understanding the Formulas

In the accompanying article Approximating Square Roots and Cube Roots, the author Ali Ibrahim Hussen has proposed
easy to use formulas for finding approximate values of the square root and cube root of an arbitrary positive number n. The formulas are found to give fairly satisfactory results, as measured by the low percentage error. In this article we explain mathematically why this is so.

## Approximating square roots and cube roots

The idea of equivalent geometric forms is used in this study to devise simple formulas to estimate the square root and the cube root of an arbitrary positive number. The resulting formulas are easy to use and they don’t take much time to calculate.
