The Resources section has rich pickings - plenty of hands-on, ready-to-use activities, ideas, posters and worksheets for teachers.
The ‘WorkShhet’ series is back, with perimeter and area. Pages 1 and 2 are a worksheet for students, while pages 3 and 4 give guidelines for the facilitator. This time we explore shapes with given perimeter or given area using the dots or the grid.
Area and perimeter are forms of measurement that are used commonly in many day-to-day activities. In particular, area is used in an intuitive way on an everyday basis when we select a plate to cover a utensil, a table cloth for a specific table, a sheet of paper to cover a book, etc. Without really knowing the specific words, children also commonly make judgements which involve an intuitive understanding of area. A question that naturally arises is: When or why do we want to know the exact size of a space? Demonstration of this point needs to happen repeatedly through real world applications.
This cross-number puzzle is a follow up to the article on Fact Families in the same issue. An addition fact family is essentially a set of three natural numbers, such that the sum of two of these numbers is the third.
Fact-Families are a group of 3 numbers {a, b, c} such that a + b = c
In 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 the Features section of this issue, we have looked at the Why and How of the celebration of a Mathematics Day.
Word problems become a stumbling block for many children, including those who are adept at operational and procedural skills. Many children develop an approach to tackling word problems based on looking for cue words – such as altogether, difference, sum and so on; but this has a very limited value. Too often, such children resort to guesswork while figuring out an operation. These children experience significantly greater math anxiety when they are confronted by word problems. Why is this?
Mathematics is the study of patterns – in numbers and in geometry, more commonly – but also in the most unexpected places. Patterns are beautiful and catch our attention. All of us notice them either in our surroundings, in clothes, in constructions, and so on.
ಕಿರಾಣಿ ಅಥವಾ ತರಕಾರಿ ಅಂಗಡಿಗಳಲ್ಲಿ ಖರೀದಿಯ ಸಮಯದಲ್ಲಿ ಹೆಚ್ಚಿನ ಮಕ್ಕಳು ಹಣದ ಬಳಕೆಯನ್ನು ನೇರವಾಗಿ ಕಾಣುತ್ತಾರೆ. ದೇಶದಾದ್ಯಂತ ಮತ್ತು ಎಲ್ಲಾ ರೀತಿಯ ವಹಿವಾಟುಗಳಲ್ಲಿ ಡಿಜಿಟಲ್ ಪಾವತಿಗಳ ಬಳಕೆಯು ಹೆಚ್ಚಿರುವುದು ನಿಜವಾದರೂ, ಕರೆನ್ಸಿ (ನಾಣ್ಯಗಳು ಮತ್ತು ನೋಟುಗಳು) ಈಗಲೂ ವಿವಿಧ ಪಾವತಿಗಳಿಗೆ ಬಳಸಲ್ಪಡುತ್ತಿದೆ, ಉದಾ: ಮನೆಗೆಲಸದವರು, ಚಮ್ಮಾರರು, ಬೀದಿಬದಿ ವ್ಯಾಪಾರಿಗಳು, ಸ್ವಯಂಚಾಲಿತ ಮಾರಾಟದ ಯಂತ್ರಗಳು ಇತ್ಯಾದಿ. ಅಲ್ಲದೆ, ವಯಸ್ಸಾದವರಿಗೆ ಇಂದಿಗೂ ನಾಣ್ಯಗಳು ಮತ್ತು ನೋಟುಗಳ ಬಳಕೆಯೇ ಇಷ್ಟ!
Most children witness the usage of money during purchase transactions at grocery stores or vegetable vendor shops. While the usage of digital payments has increased across the country and in all types of transactions, currency (coins and notes) is still used for various payments such as services offered by maids, cobblers, pavement purchases, vending machines, etc. Also, older people continue to be more comfortable with money transactions.
There are 11 types of kites (excluding rhombi) according to the poster
This poster will help your students make friends with these 11 types. Do give the students time to study it and come up with properties for each of the kites K1, K2… K11. Some important points are given below. Students are sure to come up with these or other points during the discussion, if they don’t then do share at your discretion.
The content of the PullOut section has, so far, largely been topic based and focussed on mathematical activities and pedagogy. This particular PullOut is an attempt at integrating mathematics with science concepts in order to develop responsible ways of living. The topic covered- Temperature -is appropriate for upper primary, class 6. The objectives are to understand the concept of temperature and the factors that affect it, discuss and experiment with ways of measurement of temperature and to notice its relationship to our daily living.
