A major part of the formative years of a child’s life is spent in a school and hence the
importance of making it a place of joyous learning has been engaging the attention of
educationists. The National Curriculum Framework 2005 has elaborated on the insights of
Learning without Burden to ensure that a child is not taken away from the joy of being
young by de-linking school knowledge from every day experience. One of the most
importantareasinthisrespectisregardingmathematicslearninginschools.
Mathematical phobia has been a common jargon in school parlance that has created an
elite class of good students of mathematics leaving behind a large number of students who
fear the subject. In an endeavour to impress upon the schools that this misconception
about the subject is mainly due to wrong teaching practices which do not link the subject
with real life, the Board had introduced the concept of Mathematics Laboratory in schools
uptoSecondarylevel.
It is essential to know that mathematics is very much related with real life. It is a vehicle of
communication just as every language is. Through mathematics we can describe,
understand and work with physical phenomena with utmost precision. The subject has
application in almost all walks of life. The symbols and operations are only mechanical
tools but the concepts themselves are much more than these and are very much real and
related to human life in the backdrop of the world we live in. But by projecting the subject
as dealing with the world of symbols and notations it has been painted as an abstract
subject much to be feared by students of limited capabilities. Mathematics laboratory as a
concept will be an effective tool in the hands of a teacher to illustrate to the students that
they can construct all mathematical knowledge with their own hands, enabling a smooth
transitiontoabstractthinkingcapabilities.
CBSE has already introduced the concept of Mathematics laboratory for classes IX and X
few years back in all its affiliated schools, where students are encouraged to learn the
concepts through activity work and hands on experiences. With the success of this
initiative , CBSE introduced the concept of Mathematics laboratory from classes III – VIII
also,whereactualunderstandingofbasicconceptstakeplace.
Foreword
(i)
In 2008 vide circular no.38/08, CBSE had listed a number of activities for classes III – VIII,
which could be taken up by the teachers while teaching a particular concept. The present
document gives a detailed process for doing these activities. This would help the teachers
aswellstudentsinactuallydoingtheseactivities.
I take this opportunity to thank all experts and practicing teachers who have helped in the
development of this material. I further acknowledge the contribution of Mrs. C.
Gurumurthy, Director (Academic), CBSE, for providing necessary impetus and guidance. I
would also put on record my appreciation for Dr. Srijata Das, Education Officer, for her
effortsincompletionandpublicationofthisdocument.
Suggestions from users for further improvement of this document will be highly
appreciated.

It is a common observation that a large section of student population considers
mathematics to be a dull and difficult subject. This is because of being taught in a
mechanical manner where students are made to memorize formulae/algorithms and
applytheseformulaealgorithmsinsolvingproblems.
Allthisiscreatingaphobiainthemindsofstudentstowardsthissubject.
In order to appreciate the nature of mathematics and to make mathematics learning
interesting and joyful, the teaching-learning process has to be completely revamped. The
concept of mathematics laboratory has been introduced by CBSE few years back in Class IX
and X. In 2008, CBSE extended this concept to Primary and Upper Primary classes by
identifying specific activities for Classes III-VIII based on the concepts given in NCERT text
books.
Thepresentdocumentgivesdetailedprocessforperformingtheseactivities.Carehasbeen
taken to ensure that the teachers and students are able to perform these activities with
relativeease,requiringnoexpensivematerial.
It is hoped that teachers and students will perform these activities and make mathematics
teaching-learning process a joyful one. These activities can be performed inside the
classroom, homes or some corner/room in the school where materials are easily available
to the students so that they can work with them, actively participate in the activity and
consequentlylearntoappreciateandunderstandmathematics.

  • 3. A major part of the formative years of a child’s life is spent in a school and hence the importance of making it a place of joyous learning has been engaging the attention of educationists. The National Curriculum Framework 2005 has elaborated on the insights of Learning without Burden to ensure that a child is not taken away from the joy of being young by de-linking school knowledge from every day experience. One of the most importantareasinthisrespectisregardingmathematicslearninginschools. Mathematical phobia has been a common jargon in school parlance that has created an elite class of good students of mathematics leaving behind a large number of students who fear the subject. In an endeavour to impress upon the schools that this misconception about the subject is mainly due to wrong teaching practices which do not link the subject with real life, the Board had introduced the concept of Mathematics Laboratory in schools uptoSecondarylevel. It is essential to know that mathematics is very much related with real life. It is a vehicle of communication just as every language is. Through mathematics we can describe, understand and work with physical phenomena with utmost precision. The subject has application in almost all walks of life. The symbols and operations are only mechanical tools but the concepts themselves are much more than these and are very much real and related to human life in the backdrop of the world we live in. But by projecting the subject as dealing with the world of symbols and notations it has been painted as an abstract subject much to be feared by students of limited capabilities. Mathematics laboratory as a concept will be an effective tool in the hands of a teacher to illustrate to the students that they can construct all mathematical knowledge with their own hands, enabling a smooth transitiontoabstractthinkingcapabilities. CBSE has already introduced the concept of Mathematics laboratory for classes IX and X few years back in all its affiliated schools, where students are encouraged to learn the concepts through activity work and hands on experiences. With the success of this initiative , CBSE introduced the concept of Mathematics laboratory from classes III – VIII also,whereactualunderstandingofbasicconceptstakeplace. Foreword (i)
  • 4. In 2008 vide circular no.38/08, CBSE had listed a number of activities for classes III – VIII, which could be taken up by the teachers while teaching a particular concept. The present document gives a detailed process for doing these activities. This would help the teachers aswellstudentsinactuallydoingtheseactivities. I take this opportunity to thank all experts and practicing teachers who have helped in the development of this material. I further acknowledge the contribution of Mrs. C. Gurumurthy, Director (Academic), CBSE, for providing necessary impetus and guidance. I would also put on record my appreciation for Dr. Srijata Das, Education Officer, for her effortsincompletionandpublicationofthisdocument. Suggestions from users for further improvement of this document will be highly appreciated. (Vineet Joshi) CHAIRMAN (ii)

  • 9. It is a common observation that a large section of student population considers mathematics to be a dull and difficult subject. This is because of being taught in a mechanical manner where students are made to memorize formulae/algorithms and applytheseformulaealgorithmsinsolvingproblems. Allthisiscreatingaphobiainthemindsofstudentstowardsthissubject. In order to appreciate the nature of mathematics and to make mathematics learning interesting and joyful, the teaching-learning process has to be completely revamped. The concept of mathematics laboratory has been introduced by CBSE few years back in Class IX and X. In 2008, CBSE extended this concept to Primary and Upper Primary classes by identifying specific activities for Classes III-VIII based on the concepts given in NCERT text books. Thepresentdocumentgivesdetailedprocessforperformingtheseactivities.Carehasbeen taken to ensure that the teachers and students are able to perform these activities with relativeease,requiringnoexpensivematerial. It is hoped that teachers and students will perform these activities and make mathematics teaching-learning process a joyful one. These activities can be performed inside the classroom, homes or some corner/room in the school where materials are easily available to the students so that they can work with them, actively participate in the activity and consequentlylearntoappreciateandunderstandmathematics.
