What
an exploration of the Ganak (the open abacus)
How
Core activity is a 3-base game based on Ganak.
Significant Outcome
With the grasp of abacus principle they were able
to make the meaning of “+” & “х” signs in the
expanded form of numbers.

What is place value system?
(an article “Place Value: Problem Solving and Written Assessment”
by Sharon R. Ross. 2002)“Our numeration system is characterized by the following four
mathematical properties: 1. Additive property – The quantity represented by the
whole numeral is the sum of the values represented by the
individual digits.
2. Positional property – The quantities represented by the individual digits are determined by the positions that they hold
in the whole numeral. 3. Base-ten property – The values of the positions increase
in powers of ten from right to left. 4. Multiplicative property – The value of an individual
digit is found by multiplying the face value of the digit by the value assigned to its position.”

In mainstream caseschildren are asked to write the numbers in
columns marked out as units, tens and
hundreds.
In the alternative approaches
Materials used in Whole number approachColor-coded 100 beads string - The Ganit mala
Materials used in place value based approachThe Diene’s block
The matchsticks bundle
How Numbers are taught?

The Material reviewused in Place Value based Approach
Strengths
It explain the base ten property of NumbersDevelops the grouping logic in place value
It explains & facilitates the algorithms very clearly
Issues
•These materials don’t follow the positional notation
system. The column are externally imposed to makesimilarity with.
Example 1345. If so, then we can write this number as 4153• Strength & need of the additive (multiplicative) composition of
numbers is simply lost. It comes exactly same in Ganak as we see
in our number system.

The Ganak as solution
‘Ganak’ is a bit modified version of roman
abacus, was used in ‘Bal Vaigyanik’ as a tool to
teach ‘decimal’ & ‘place value’
“Dr Vijay Verma even says in his article that the
Abacus was widely used other than India and
perhaps this affected the evaluation of number inthose areas” . This, at least, implies that the
Abacus is very much similar to our numbers
system.

Conceptual Map of the Study method
The children enjo ed pla ing the three base game
8/3/2019 Pramod Maithil: A Ganak Based Game
http://slidepdf.com/reader/full/pramod-maithil-a-ganak-based-game 24/35
The children enjoyed playing the three base game
and got hold of the game
They also learnt naming the boxes in order to know
the value of the combination.
All the children havelearnt to play it
8/3/2019 Pramod Maithil: A Ganak Based Game
http://slidepdf.com/reader/full/pramod-maithil-a-ganak-based-game 25/35
The entire class was able to associate the
combination with quantity (number)
8/3/2019 Pramod Maithil: A Ganak Based Game
http://slidepdf.com/reader/full/pramod-maithil-a-ganak-based-game 26/35
They were able to write the combination in
sequence. All selected 11 children even more could
do this for sure
They also used the name
of the boxes in order to
know the value of the
combination.
3 out of 11 did it by
counting from 1 to 56.

After pictorial
representation
they were able
to write using
Indo-Arabicsymbols as
well. All
selected 11
children were
able to writethe two base
numbers.
3 children
wrote up to 7
to 8 places of 3
base numbers.
The children designed their own game of different

http://slidepdf.com/reader/full/pramod-maithil-a-ganak-based-game 28/35
The children designed their own game of different
bases by extending the part of a box and did all the
exercises which they did with 3 base game
The class was
divided in to 4
groups and all
the groups
designed theirgame.
Then to my surprise the children (8 out of 11) were

Then to my surprise the children (8 out of 11) were
now able to write the pebble combination in the form
of additive (multiplicative) composition in order to
calculate value of the number.

An interesting Observation
He named the boxes
1, 5 & 25. Then he
added first 25+5+1
for the first row of
pebbles thendoubled it and then
added the unit box’s
left out pebble and
got the answer 63

Conclusion & Recommendations

Conclusion & Recommendations
It is also worth sharing that this small project was taken up in
order to learn the research methodology so this should not be seen
as cutting age research but certainly it can be treated as a pilot
study.
Although I am interested to see how the Ganak can be explored?
But I am still left with few issues/questions on the study if it is
seen as pilot study of efficacy of Ganak to teach place value.
Conceptual issues 1.The connection between the positional notation system and our
numbers seems a jump. I only assume that this understanding
will help a child to understand number batter in future?
2.Why place value should be taught?
Issues on method
1.I am unable to give justified enough rationale why did I conduct
the study in grade 6?
2.Various other factors like motivated teacher, time & syllabus
constrains and school management .
