Mathematics and Life 57 The 11 letter magic

 The 11 letter magic 


Today I am posting my creation done in 1992 which got into print in 1993. That time, as an active school maths teacher, I wrote this and got printed a large number of posters. After nearly 30 years, I still agree with most points, although the perspective has changed. That time was aimed towards students to do,  now it aimed at teachers like myself.



Let me rewrite them here as the image is not clear enough.


Master the basics. The teacher should try to first create a base to introduce new topics. Is it surprising that in spite of so many education commissions, reports etc, we do not have a known list of basics a child entering a class is supposed to know ? Please share if you know any.

 Approach the problem properly. More often than not, due to teaching not being process oriented, students spend a lot of productive time in trial and error. 

Think before you solve. We teachers hardly teach strategy to attack a problem. Our emphasis, training, is to just kill the problem and not solve it efficiently.

Have confidence in your working. It is the most common scene to see very kids erase more than they write. Lack of confidence in processes is visible and we, as the teachers, need to empower the child. Specially the girl child who are stereotyped to believe they are no good at mathematics.


Estimate the answer. This skill is very useful in most competitive examinations where many times looking at the options carefully one can sense the answer.


Minimize the calculation errors and process. Once again a function of conceptual clarity, this skill needs to be developed at the earliest stage.


Apply the correct formula. More often than not, due to poor conceptual clarity students often go the wrong route and realize much later that they have applied a wrong formula. Therefore, give more attention to concept formation, conceptual clarity than mugging up formulas mindlessly and applying indiscriminately.


Tricks to calculate faster are surely welcome in highly competitive environment. Knowing concepts properly, using knowledge of tables carefully are the best tricks to do fast calculations.


Invent new solutions, approaches to solve. Again this happens once your concepts, processes are in place and now you wish to go for excellence. 


Comprehend the problem properly. Specially in the lower classes, children tend to hurry up to solve problems and unfortunately, some parents and even teachers train them to look for hinting words and solve fast. But this habit may give great results when the degree of freedom is less or sums are direct. However, in more complex problems, this does not work and becomes counterproductive. We need to make children understand the problems properly rather than doing quick fixes.


Study maths regularly. Reapproaching, revising, concepts is one of the surest ways to get excellence in maths. Doing maths needs to be part of daily habits.

My Journey as a Maths Teacher – Part 2

  🧒 From Grade 3 to Guiding Future Teachers It gives me immense pleasure to be of some help to my younger mathematics teaching colleagues like Shruti Goel, Laly, Preeti Garg, Misha Nambiar, Rajendra Paliwal , and many others—across subjects and across schools. But things weren’t always this way. 📘 The Indore Phase – Simplicity, Struggle, and Silent Growth After leaving Mumbai in 1988, I served as a school teacher at Choithram School, Indore , till 1992. I even taught Grades 3 to 5 in a single session . Yet, the spirit was always high. I loved taking classes, creating activity sheets, and even wrote articles I mailed to U.S. education journals —long before emails were common. If there was one shortcoming I admit, it was in checking large stacks of answer books. I often rationalised, “I’m a creative person, so it’s okay.” In hindsight, it wasn’t—but the honesty helped me grow. 🔄 The Decade of Churn (1988–1997) It was a whirlwind decade. Imagine this combination: Ph.D. ...

Mathematics and Life 1 Introduction to the article series by Beyond Abacus

Purpose of the series is to explain various basic mathematics concepts in simple language connecting concepts to examples from life,business, science, day to day life. It will be our special emphasise to develop what Dr. Prakash Moghe calls the math - language interface. That is, showing similarity between the words used in daily language and mathematics like point, ray, interest and so on......     Audience This series of posts is for everyone who wants to understand, learn, revise, apply maths concepts, formulae, and wants to develop Problem Solving Approach, critical thinking, design thinking, and mathematical thinking. Agewise , from age 6 to the time one wants to learn / revise / teach basic maths will find these posts useful in their own ways. Frequency of posts At least one post a day has been planned. Length of posts Each post will be self content, so will be long enough to elaborate the point and short enough to keep the reader engaged. The reach Each post wil...
