ISSUE No. 77
A warm welcome to our new subscribers.
Vedic Mathematics is becoming increasingly popular as more and more people are
introduced to the beautifully unified and easy Vedic methods. The purpose of
this Newsletter is to provide information about developments in education and
research and books, articles, courses, talks etc., and also to bring together
those working with Vedic Mathematics. If you are working with Vedic Mathematics
- teaching it or doing research - please contact us and let us include you and
some description of your work in the Newsletter. Perhaps you would like to submit
an article for inclusion in a later issue or tell us about a course or talk
you will be giving or have given. If you are learning Vedic Maths, let us know
how you are getting on and what you think of this system.
This issue's article is from Robert McNeill who has taught mathematics for over
40 years to students aged from 5 to 18. He is currently Headmaster at St James
Independent School for 3½ to 11 year olds in Stockport, UK.
VEDIC MATHS AS A TEACHING PARADIGM
As a young student-teacher, I was most fortunate to be introduced to Vedic
Mathematics* at an early stage in my career. Much has been discovered in the
class-room of the beauty and intelligence of this remarkable system and I hope
to share some of these insights in this article.
Whilst the magic of Vedic Mathematics can often be used to raise the enthusiasm
of a flagging class or to maintain the interest leading up to the end of term,
nevertheless the most significant part of the study of Vedic Mathematics*, in
my view, has been the general effect on the teaching of mathematics. Experience
shows that Vedic Mathematics has much to commend it as a paradigm for teaching.
A) The use of language
The 16 sutras and sub-sutras are a unique way of encapsulating a process in
a verbal statement. For instance, the statement "Vertically and Crosswise"
contains the essence of the process and at the same time acts as short, verbal
reminder. According to Katyayana, "A sutra is of the very fewest syllables,
unambiguous, expressing the essence of a subject, of universal application and
agreeable to mind and tongue." Certainly, many of the Vedic Mathematics
sutras meet these criteria.
The technique of verbalising a process is often used by teachers when teaching
students how to do a calculation. For example, we have an algebraic formula
for the area of a triangle as:
A ½ bh
This will often be stated as "The area of a triangle is half the base
times height". Some students, being less comfortable with an algebraic
formula, are quite at home with a verbal statement.
Children enjoy developing their own word formulas. For instance, one class came
up with the statement for rounding numbers, "If the next digit is five
or more, increase by one, the one before." This was unnecessary for some
but for others, who were struggling, it made the whole operation a lot easier.
B) Demonstrating first and explaining later.
A good example of this is the Nikhilam method of multiplication. Bharati Krsna, whilst giving the algebraic explanation early on, does not dwell on it. He spends most of the time going through examples and this is preferable for most learners, especially young ones. In practice, I have found that students are very happy to experience the magic via a large number of examples before enquiring about the logic. When their experience has built up then students are much more appreciative of the logic. In the meantime, they are growing in confidence and in the understanding of number in practice.
C) Distilling the universal from the particular
The example that comes to mind here is multiplying by 9, 99, 999 etc. Bharati Krsna, in chapter 2, encourages the reader to look at a table of products using a single digit multiplier of nine. He then extends to 2 digit multipliers and notes the rule holds good there as well. This procedure is the basis of investigation, very popular in schools today. Investigations inspire enthusiasm and lead the pupils to look for themselves. This is an important element of practical work in science.
D) Proving a general case and using it as a formula
In chapter 11, Bharati Krsna introduces solving equations and the first type
he gives is 2x = 7 = x + 9 which he solves by the conventional method first.
He then solves the general case ax + b = cx + d and uses the solution as a formula
for further examples. Bharati Krsna encourages the student to use the general
formula
x = (d - b)/(a - c)
which he says "should be a short and simple mental process." But he
does insist on practice to gain "mastery over it"!
Solving equations by this method is very effective but in the present climate
of educational opinion, not one that is appreciated by examiners or teachers
brought up on the traditional methods. Examiners do like to see some recognisable
working written out, otherwise students may be penalised.
We do not always insist on proving formulas however. Students commonly use a
formula for the area of a triangle without having to demonstrate a reason for
its validity on every occasion. For some students, being able to find the answer
to a simultaneous equation simply by following a rule is very advantageous,
whilst others prefer to see how the method works at each stage. Vedic Maths
offers the opportunity for both.
E) Using multiple stages when introducing a new topic
This, for me, has been one of the most useful tools for teaching mathematics
from Bharati Krsna's book. I have used it with great effect on many occasions
when introducing a new topic.
Once again referring to chapter 11, Bharati Krsna begins by developing a formula
for equations of the type ax + b = cx + d as previously mentioned. In a similar
way he develops a formula for type 2 which is represented by (x + a)(x + b)
= (x + c)(x + d). Type 3 and type 4 follow and formulas are developed in a similar
way. The point I wish to highlight is the use of the staged types of equations,
with each type being either a little more involved than the previous type, or
a development from it.
I have used this successfully to introduce a range of topics at all levels of
teaching mathematics. Take basic percentages for instance: type I might be learning
to express one quantity as a percentage of another. Type 2 might be finding
a percentage of a quantity. Type 3 might be increasing or decreasing by a percentage
and type 4 might be finding an original amount, knowing an increased or decreased
amount. The actual types are not important. What is important, is giving the
students a sense of a structure which is progressive. This is enormously beneficial
for students and gives them confidence when learning a topic for the first time.
F) Using Vinculum Notation
This, for me, is the most revolutionary part of the whole of the Vedic mathematics approach. I have used this on occasion over the years, but only with bright students, and then in limited circumstances. When using it, much practice is required in transposing numbers from one form to another. This is a brilliant example of Vedic Mathematics using something that is well known but overlooked. For those of us old enough to remember, bar notation was used in logarithmic calculations. The use of the vinculum is obviously at the heart of many mental strategies. For instance, adding 29 to 56 we add 30 and subtract one which is basically adding 3 bar 1. How much easier it would be if students were brought up on this concept from an early age.
I now find that Vedic Mathematics, rather than being a bolt- on, fun option
in my teaching, actually pervades and supports the whole of the teaching from
the very centre. I may not teach Nikhilam multiplication to every class but
the principles underlying Vedic Mathematics are still there at the heart of
my teaching in every lesson. For this I am extremely grateful.

VEDIC MATHEMATICS BECOMING POPULAR AGAIN
This is a nice article from the New Indian Express:
http://ibnlive.in.com/news/vedic-mathematics-becoming-popular-again/204977-60-122.html
E-GURUKUL COURSE
This online teacher training course in Vedic Mathematics started on 2nd October and is going extremely well. The extracts below from Forum posts will give you some idea.
"Lesson 17 on Natural maths was fun. After watching the video, I prepared
the following worksheet, based on the video and tried it with my topmost GCSE
group on Wednesday , the 9th November during my one hour lesson with them. I
gave them 45 minutes to do the work and then explained all questions to them
by Vedic Maths method quoting the sutras - "Spot the obvious and If one
is in ratio, the other is zero". They were amazed and would never forget
the lesson for rest of their life because they had really struggled doing the
questions by normal methods."
Rajni Obhrai
"I started teaching few simple VM sutras to my 7 year old - multiplying
by 5 and multiplying by 11 (my assignment 1) and she gets so excited and can't
wait to learn all of VM. She keeps asking me when will i do my next VM online
class, she wants to listen with me. I truly believe kids get more interested
in maths because of VM."
Dokiparthi Venkat
"I have found that VM has opened my mind and expanded the possibilities
when dealing with different maths problems. Some of the examples in the spot
the obvious part of the lesson I was able to quickly pick up. Prior to learning
about VM, nothing would have been obvious, nor would it have been spotted. This
expanded vision and opened mind allows one to work a lot smarter, with minimal
effort."
Damen Pitiroi
"I just finished the 17th lesson , and I think it really applies to the
whole life and not just only math, it gives us a hint about problem solving
and being flexible with the solution so that we find multiple ways of getting
out of a problem , as they said " the more flexible always control the
situation. Also I like the versatility of Vedic math as Andrew mentioned earlier
, it gives an impression of being free rather than being limited to one way
of solving, just in case of multiplication like 16*18 I solve it with about
4 method : as 10 base , 20 base , vertical and crosswise and by adding and subtracting
, it gives you the feeling of control for solving."
Mohammed Qawasmi
"I have also received responses like "why are they not teaching this
in all schools?" or "I wish I was taught this system when I was in
school" or "I feel ripped off for not being taught this way,"
which were also my responses when I stumbled upon VM.
I think as trainers in training we not only need to learn the methods well to
be able to teach, we need to go that little bit further to understand how and
why the methods work in order to deepen our own understanding and in time that
of the people we will be teaching.
As someone once said: 'The difference between ordinary and extraordinary is
that little extra'."
Damen Pitiroi
"Over thinking is not necessary. That is what Vedic Math shows us. Over
thinking is the conventional way. Vedic is about working smart, not hard."
Mia Liley
"I was watching my lessons 13, 14 and 15 and my daughter asked me to teach
her that. So I went ahead and taught her hardly for 5 -10min "multiplication
near a base" and so surprised to see that she got it right away! She is
going to be 7yrs old in few months. She said- I made a connection. She has been
asking--- is there a 7 point circle ?, 6 point circle?"
Dipali G
"Really exciting to learn the powers of VM techniques. When I shared near
base / proportionately methods to 3 kids (neighbours), they are so enthusiastic
to learn all the techniques immediately!!"
Muthu S
"Was showing my 11 yr old the method of subtracting from base numbers (all
from 9 last from 10) and he got it right away. I started with lets race and
I got it faster each time. Once I explained he was so excited and wanted already
go talk to his teacher and of course show off with his friends. I also walked
him through adding fractions and I think I already have one person completely
sold on this topic. I asked him to wait until I go through all me classes and
give him all the basics in order. But I definitely see the excitement and hence
acceptance the system can bring in.
Enjoying every moment of the learning.."
