There is another method, which all students can understand is
1. Give clear idea of a rational number.
Pi= 3.1415926535897932384626433832795028841971693993751 .......
If you cut some digits and set the denominator for the resulting fraction then it would again be rational.
This is non repeating and never ending.
There are chances that children can understand the depth of the concept.

Please continue the discussion.

Sir,
22/7 is not irrational. The value of pi is different from the quotient of 22/7. 22/7 is only an approximation that is used by primary school children to use for calculation. It is recuring and non terminating decimal. But pi is non-recuring and non-terminating.
Sir give the conclusion that pi is rational or irrational.because if we devoided 22 by 7 we get repeating factor 142857.how it is irrational ? And mention how we get the pi value as 3.1415926535....

Yes, Pi is not 22/7. Pi is the ratio of circumferrence to diameter which is written approximately as 22/7. The ratio itself is an irrational number, meaning it is non recurring and non terminating.
while 22/7 is a rational number, being in the form p/q where p and are integers and q<>0

Sure sir.
The 4 day long training by Novus STS a techonogy group for private and govt teachers of belthangady I think may override many other groups if it brings pressure on Governments to subsidise schools to purchase its products and software which runs on Windows. I will get home and give you details with picture.
The link to
Tharanath Achar
The link to NovusSTS is
http://www.novussts.com/
The training involved 1. lectures on most basic concepts of Mathematics and Science.
2. hands on experience on how to operate Explorelearning tool.
3. Gizmos on various concepts
4. Padagogy.
5. PPT presentation of NCF2005 followed by discussion.
6. Group discussion and presentation.
7. Formative Assessment: We are given a remote like devises called Clicker which had some 10 buttons. Multiple choise question paper is shot on LCD screen and we are told to press button which carried right answer. It took 5 minutes to ask questions and press answer. The presenter displayed our 20 scores in .xls file which he told us would be useful to email the scores of students to their parents, to make consolidated mark register on daily basis. It is very useful in Formative assessment.
But the trasmitter costs Rs.10000, one clicker costs 2500. One laptop, and a LCD projector, Screen, etc. Our government school can not afford to buy this gadgets which may cost more than 200000 for a class of 20 students. It is called Class Room Response System.
It is almost analogues to the STF training, but here technology is everything. The points above 2 and 3 resembles our usage Phet and Geogebra. You have to register, pay and subscribe to the Gizmos. It is online lab. We are given a CD as a trial version for one month and a hand book.
I and some of the teachers who have taken our STF training did not seem to have enjoyed this training.

Guru Sir,
Your last brief mail seem to address me only. We all should be informed of what decision our higher officers would take on things like ICT in schools. I hope you will forward the minutes of official meetings on ICT.
I will be the happiest when two of your principles become a practice backed by the Government orders : not by the encouragement from lower end.
Regards.
thank you sir for sharing the information
on 11.1.13 IT for Change organised a 1 day seminar along with Dept of Primary and Secondary Education for directors, joint directors and select deputy directors. Secretary and CPI wer also present and few NGOs
the purpose of the seminar was to discuss ICTs in education and evolve some guiding principles for integrating ICTs into education.
one principle which was mentioned by many participants was to make ICT non-vendor driven and to make needs of education paramount ... will share the highlights of this seminar later
(a second principle was the use of public resources and avoid proprietary resources)
regards
Guru
