Second Intra School Mathematics Olympiad- RESULT

Dear All,

The Second Intra School Mathematics Olympiad was held on 23 November 2011.

Hopefully, it was a great learning experience for all. It surely provided an extended platform for all the participating students and it is wished that it is utilized to its fullest.

As it was promised to declare the result on 22 December (hope you remember!) i.e. birthday of great Indian mathematician Srinivasa Ramanujan who acted as a pioneer for many mathematicians. Despite of no proper training in pure mathematics he made special and extraordinary contributions in mathematical analysis, number theory, infinite series etc.

Here are many young Ramanujan’s in our school who had performed very well in the exam. Check out the result here:

III -V RANK HOLDERS     III -V MERIT HOLDERS

VI-VIIIRANK HOLDERS    VI-VIII MERIT HOLDERS

IX-XII RANK HOLDERS    IX-XII MERIT HOLDERS

Congratulations to all the rank and merit holders for their brilliant performance in the  Olympiad.

Second Intra School Mathematics Olympiad

Dear All

Mathematics, often called as language of nature has become an integral part of everyone’s life. In today's highly competitive world, one has to bear a lot of mental stress and also have to get involved in so many things in order to acquire knowledge. This is where co-scholastic activities play a very significant role. They provide the much needed exposure for a student.
CRPF Public School has fulfilled its motto of striving towards excellence by organizing and successfully completing its Second Intra School Mathematics Olympiad on 23^rd November 2011. Around 450 students enthusiastically participated in the Olympiad held in school premises.

Such Olympiads and events provide a great and extended platform for the students to nurture and showcase their ability and talent. It was a towering learning experience for the students of the school from class III to XII. To encourage students, merit certificates will be given to those scoring at least 60% along with the normal prizes for the top scorers.

I hope that all the participating students must have done well in the exam. To access your performance, check out the solution keys of the question papers below:-

Question papers:-

Class III      Class IV          Class V

Class VI      Class VII     Class VIII

Class IX      Class X        Class XI       Class XII

Solutions keys:-

Class III      Class IV          Class V

Class VI      Class VII     Class VIII

Class IX      Class X        Class XI       Class XII

The result would be declared on 22^nd December 2011 (birth date of great Indian Mathematician Srinivasa Ramanujan) and would be available here.

Wishing you all the best!!!

Second Intra School Mathematics Olympiad

 Dear all,

The Mathematics Department of CRPF Public School is back with the Second Intra-School Mathematics Olympiad, to be held on 23 November 2011 (Wednesday) in the school premises only. The last date for registration is 18 November 2011 (Friday), so hurry up. Go, get yourself registered!

The Mathematics Department, striving towards excellence has welcomed all the suggestions, opinions and advices after the completion of last year’s First Intra-School Mathematics Olympiad and has tried its best to incorporate most of the valuable suggestions made by the students, participants, teachers, parents and others. As a consequence, unlike last year (where the entire question paper was objective), this year, participants will face a 40% subjective paper too. Also, to felicitate the efforts and intelligence of participants, the department has decided to award a certificate of merit to every participant this year scoring at least 60%, other than the regular prizes for top scorers.

Consult your Math teacher for other details or queries and check out the following links for the circular, sample papers and last year’s Olympiad papers:

Here are the Sample Papers:

CLASS VI        CLASS VII         CLASS VIII

Making Mathematics Simpler! NCERT TEXTBOOK SOLUTIONS - XII Mathematics

Dear Students Of Class XII

It is observed that many a times, after teachers have explained certain topics and have discussed certain questions from the related exercise, not all the questions of the exercise are being solved/attempted by the students. It is practically impossible and undesirable for the teacher to solve each and every question in the class itself. The remaining questions are supposed to be attempted by the student at home. However, it is very much possible that the student is unable to successfully solve all of them.

After discussing this issue with the students, I have decided to make the NCERT textbook solutions available at my blog. The solutions are taken from www.meritnation.com. You can directly visit this website but you will first need to register there and the solution of only one question can be seen at a time. This might be a cumbersome process while you are checking your answers. Therefore, to  save the student’s time and to make those solutions available to all the unregistered students as well, I have decided to upload the solutions here from time to time. 

At the same time, I would want that the students do not check the solutions before they have tried the questions themselves. Hence, I’ll be uploading the solutions here only after the exercise has been covered in the class.

I’m also trying to upload the solutions of all the chapters which have been already covered in the school i.e. chapters 1-5.

Check this post frequently to get the latest updates and keep doing mathematics!

Do you know today is a special day, Mathematically...

Dear All


Do you know what’s special about today,   22 July? 
Well, today is Pi Approximation Day.

Pi Approximation Day celebrates the mathematical constant π (pi). It is observed on July 22, due to π being roughly equal to 22/7.

The fractional approximation of π ,²²⁄₇, resembles the date July 22 in the day/month format, where it is written 22/7. Pi Approximation Day is therefore celebrated on July 22.

In geometry, pi is defined as the ratio of a circle's circumference to its diameter. July 22, often written as 22/7, is an appropriate day to explore pi, since 22 divided by 7 is an approximation of pi.

Pi Approximation Day is celebrated in a number of ways, including contests to memorize pi to the most decimal places, solving math problems involving pi, discovering the history of pi, ruminating on how life would be different without pi and—of course—eating pie.

So, enjoy this mathematical day ...

Class Test held in XII (All Sections)

Dear All,

Today a class test based on differentiation(class XII) was conducted. The demotivating factor was that 18 students were absent in XII A (Science students). All those who were absent today will give the test later.
Anyways, I was prepared with two different papers, one for XII A and other for XII B.
Here are the test papers along with solutions.

For class XII B and C   

  

                                 

For class XII A

Here are the solutions:

Class XII A    Class XII B,C

It is hoped that students must have done well. Please check the methods and 'how to' give the answers.

Models of Platonic & Archimedean Solids

Dear All

Finally, I am done… I had been working for the last three weeks over my birthday gift for myself! I have finally completed making the three-dimensional models of Platonic and Archimedean Solids. Yet again! Surely, those forty-fifty hours while I was making them paid off well. 

Although I had made these solids five years ago as well but the methodology and the type of paper used then was not the best way they could be. And I figured that out soon when I saw those models perishing. But of course, my past experience helped me a lot this time.

I got the nets of these solids printed out on 12”X18” photo paper and then used ‘half-cut’ method on paper to get the proper nets and hence the solids.

Click here to see the step wise procedure I followed.

Click here to download all the models I have made:

To know more about these solids click here and here.

To check the various good resources, web links click here.

To view these solids, download this program.

If you wish to make these solids for yourself, download this file and enjoy!

Good luck!
And yes, Happy Birthday to me J

Amit Sir
