A resource for school mathematics

The joy of mathematics – a phrase that has been used in the national curriculum framework – has to be handled mindfully and explored in depth. What is the joy of mathematics? Is it just about fun classrooms and frivolous mathematics? Can we find joy in the rigour of mathematics? Isn’t that an oxymoron?

Here we are at the second issue of the new at right angles, where we consciously attempt to connect with pedagogical issues associated with teaching mathematics at the primary school level. A big thank you to all our authors who have shared their experiences and learning and to our readers who have reached out in appreciation and provided valuable critique.

‘Big books’ are oversized story books, often containing large pictures and fewer words in large print. This allows for multiple readers to access it and read together comfortably. In the past few decades, the use of big books has gained prominence for ‘shared reading’ experiences with young children in the classroom (karges-bone, 1992) (3).

It was a winter day, and all the students gathered on the ground for assembly. The air was filled with the melodious notes of the national anthem and other uplifting tunes, setting the stage for a day of learning. As the last strains of music faded away, the teacher asked, “who will tell me the table of 14?” some students raised their hands while some started hiding behind others. “Let’s start from class 3, aryan you tell me, what is 14 times 7?” aryan seemed nervous and thou

This article shares my experiences of teaching in a government school in rural rajasthan (oct-nov 2022) as part of the field practice of my m.a. Education programme at azim premji university. The experience in the field helped me understand the difficulties children face specifically in understanding mathematical concepts. I observed and attempted to address the challenges children faced in understanding angles in different orientations and in the measurement of angles. There

Triangular numbers have their name because a triangular number of circles can be arranged in the form of an equilateral triangle, as shown in figure 1.

Our friend laurie was born in 1962, and this year she will turn 62 years old. We found this interesting. We told her this is her ‘special year.’ we then wondered how individuals can determine their special year, the year in which the last two digits of their birth year match their age, given their birth year, b. The interested reader may explore this before continuing reading.

We routinely use our calculator to obtain the sine of a given angle. (In earlier times we used published tables!) little do we realize that a debt of gratitude is owed to the fifth century indian savant aryabhata who was the first to tell us about the sine function and create the first table of sines — in his seminal work, the aryabhatiya (499 ce). In this article, we describe the trigonometric identities used by aryabhata to obtain the table of sines.

Picture yourself as a lab technician during a pandemic, faced with a critical challenge. Resources are scarce, and you need to identify which one of the 15 samples is contaminated with a virus. The catch? You have only 4 test tubes at your disposal, and you want to filter out negative samples using only these 4 test tubes in the most efficient manner. Can you detect the ‘poisoned’ sample?
