Weaving in mathematics
Full text linkIn January 2025, two editors of At Right Angles made a visit to the District Institutes of the Azim Premji Foundation at Bhopal and Damoh. As part of this visit, they spent time at some
of the schools that the Resource Persons of the Foundation interact with. This Pullout is a follow up of the observations made by Padmapriya Shirali who was part of this expedition.
In Padmapriya’s words: In the primary and middle school classrooms at Bhopal, I noticed a lot of beautiful artwork created by students displayed on the bulletin boards. Sneha, who was with
me remarked on how such interest in art could be used in mathematical learning. This article is an exploration of how we connect an enjoyable and satisfying act such as weaving, with mathematics
Electoral roll revision in Bihar and Marathi imposition in Maharashtra have a common thread: Migrant workers
No full textThe present political moment in India is another demonstration of the now routine politics of alienation and exclusion. On the one hand, the Election Commission has announced a revision of the voter list in Bihar, requiring elaborate paperwork that effectively stands to exclude millions of poor migrant workers spread across the country. On the other hand, multiple parties have made a great show over the language issue in Maharashtra — many migrants have recently been beaten up for not speaking Marathi — whose primary target lies in the vilification of poor immigrant workers. This is a growing trend across southern states where the opposition to Hindi imposition by the Centre has been countered by the imposition of state languages on precarious “outsiders”. Such disenfranchisement of the mobile poor at both origin and destination states in India is a threat to their basic citizenship rights
Rural Multidimensional deprivation in Jharkhand : A data-driven analysis 2025
Full text linkThis report constructs a Rural Multidimensional Deprivation Index (RDI) for measuring deprivation in Jharkhand. An important feature of the index is that it is constructed using indicators on provisioning of basic infrastructural amenities at the village level. This is different from the usual poverty indices that are composed of financial indicators such as income or consumption; or indicators measuring development outcomes such as educational or nutritional levels. Observing the provisioning of basic infrastructural amenities, this report makes focused policy suggestions that can be easily implemented by functionaries working on the ground. The data for the index is sourced from the Mission Antyodaya Survey, which was carried out in 2019 at the village level across the country. The survey collects data related to provisioning and outcome of basic amenities in villages, along with demographic and socioeconomic variables. Because this is a periodic survey, it enables us to track the developmental progress of each village, district, state and the country over time. In total, there are about 182 variables that were captured in the 2019 round. The survey covers 31,175 out of 32,620 villages in Jharkhand, which is 95.6 percent of the total number of villages in the state; and 6,48,358 out of 6,67,933 villages in India, or 97.1 percent of the villages in the country

Saving the Chevella Banyans: Case study of a citizen's movement
Full text linkThis case study, documents the trials, tribulations and victories of a citizen’s movement to protect the environment — in this case the Chevella banyans. These banyans that are of ecological, historical and cultural importance were under threat of being axed for a road widening project. This case study can be used as a teaching resource in undergraduate and postgraduate programmes, and by civil society organisations and citizens as a guiding document to understand how they can contribute to protecting the environment, the strategies they can apply and the challenges they might face
Learning to measure temperature with a paper thermometer
Full text linkLearning to use a thermometer to make accurate temperature
measurements is an important skill for middle-stage science students. How do we use a paper model of a thermometer to help them develop this skill
Does an ‘empty’ tumbler contain air?
Full text linkStudents learn about the properties of matter in Grade VI. But can they
connect these concepts with observations and experiences of air from
their everyday world? Can we use an empty tumbler and a bucket of water to help them make these connections
Teacher’s guide: Visualising sound and light as waves and comparing their speeds
Full text linkLightning and thunder evoke strong feelings, such as fear, awe, excitement, and mystery. Students are inherently curious about natural phenomena that are so dramatic. They also have many questions about how these two are related. Saurabh Deka and Anurag
Tiwari explore this question in their article titled ‘How are thunder and lightning related?’. In this article, they share how the sound of thunder can be used to estimate the distance of a lightning strike from our location
