MATHEMATICS
(CODE NO. 041)
The Syllabus in the subject of Mathematics has undergone changes from time to time in accordance with
growth of the subject and emerging needs of the society. The present revised syllabus has been designed in accordance
with National Curriculum Framework 2005 and as per guidelines given in Focus Group on Teaching of Mathematics
which is to meet the emerging needs of all categories of students. Motivating the topics from real life problems and
other subject areas, greater emphasis has been laid on applications of various concepts.
The curriculum at Secondary stage primarily aims at enhancing the capacity of students to employ Mathematics
in solving day-to-day life problems and studying the subject as a separate discipline. It is expected that students should
acquire the ability to solve problems using algebraic methods and apply the knowledge of simple trigonometry to solve
problems of heights and distances. Carrying out experiments with numbers and forms of geometry, framing hypothesis
and verifying these with further observations form inherent part of Mathematics learning at this stage. The proposed
curriculum includes the study of number system, algebra, geometry, trigonometry, mensuration, statistics, graphs and
coordinate geometry etc.
The teaching of Mathematics should be imparted through activities which may involve the use of concrete
materials, models, patterns, charts, pictures posters, games, puzzles and experiments.
OBJECTIVES
The broad objectives of teaching of Mathematics at secondary stage are to help the learners to:
consolidate the Mathematical knowledge and skills acquired at the upper primary stage;
acquire knowledge and understanding, particularly by way of motivation and visualization, of basic concepts,
terms, principles and symbols and underlying processes and skills.
develop mastery of basic algebraic skills;
develop drawing skills;
feel the flow of reasons while proving a result or solving a problem.
apply the knowledge and skills acquired to solve problems and wherever possible, by more than one
method.
to develop positive ability to think, analyze and articulate logically;
to develop awareness of the need for national integration, protection of environment, observance of small
family norms, removal of social barriers, elimination of sex biases;
to develop necessary skills to work with modern technological devices such as calculators, computers
etc;
to develop interest in Mathematics as a problem-solving tool in various fields for its beautiful structures
and patterns, etc;
to develop reverence and respect towards great Mathematicians for their contributions to the field of
Mathematics.
to develope interest in the subject by participating in related competitions.
to acquaint students with different aspects of mathematics used in daily life.
to develop an interest in students to study mathematics as a discipline.

SCIENCE
(Code No. 086 / 090)
The subject of Science plays an important role in developing in children well-defined abilities in cognitive,
affective and psychomotor domains. It augments the spirit of enquiry, creativity, objectivity and asthetic sensibility.
Whereas the upper primary stage demands that plentiful opportunities should be provided to the students to
engage them with the processes of science like observing, recording observations, drawing, tabulation, plotting
graphs etc., the secondary stage expects abstraction and quantitative reasoning to occupy a more central place in the
teaching and learning of Science. Thus, the idea of atoms and molecules being the building blocks of matter makes
its appearance, as does Newton's law of Gravitation.
The present syllabus has been designed around six broad themes viz. Food, Materials, the world of the
living, how things work, moving things, people and ideas, natural phenomenon and natural reasources. Special care
has been taken to avoid temptation of adding too many concepts than can be comfortably learnt in the given time
frame. No attempt has been made to be comprehensive.
At this stage, while science is still a common subject, the disciplines of Physics, Chemistry and Biology
begin to emerge. The students should be exposed to experiences as well as modes of reasoning that are typical of the
subject.

SOCIAL SCIENCE
(CODE NO. 087)
RATIONALE
Social Sciences is a compulsory subject upto secondary stage of school education. It is an integral component of
general education because it helps the learners in understanding the environment in its totality and developing a broader
perspective and an empirical, reasonable and humane outlook. This is of crucial importance because it helps them
grow into well-informed and responsible citizens with necessary attributes and skills for being able to participate and
contribute effectively in the process of development and nation-building.
The social sciences curriculum draws its content mainly from geography, history, civics and economics. Some elements
of sociology and commerce are also included. Together they provide a comprehensive view of society-over space and
time, and in relation to each other. Each subject’s distinct methods of enquiry help the learners study society from
different angles and form a holistic view.
OBJECTIVES
The main objectives of this syllabus are :
to develop an understanding of the processes of change and development-both in terms of time and space, through
which human societies have evolved.
to make learners realise that the process of change is continuous and any event or phenomenon or issue cannot be
viewed in isolation but in a wider context of time and space.
to develop an understanding of contemporary India with its historical perspective, of the basic framework of the
goals and policies of national development in independent India, and of the process of change with appropriate
connections to world development.
to deepen knowledge about and understanding of India’s freedom struggle and of the values and ideals that it
represented, and to develop an appreciation of the contributions made by people of all sections and regions of the
country.
to help learners understand and cherish the values enshrined in the Indian Constitution and to prepare them for their
roles and responsibilities as effective citizens of a democratic society.
to deepen the knowledge and understanding of India’s environment in its totality, their interactive processes and
effects on the future quality of people's lives
to facilitate the learners to understand and appreciate the diversity in the land and people of the country with its
underlying unity.
to develop an appreciation of the richness and variety of India’s heritage-both natural and cultural and the need for
its preservation.
to promote an understanding of the issues and challenges of contemporary India-environmental, economic and
social, as part of the development process.
to help pupils acquire knowledge, skills and understanding to face the challenges of contemporary society as
individuals and groups and learn the art of living a confident and stress-free life as well as participating effectively
in the community
to develop scientific temper by promoting the spirit of enquiry and following a rational and objective approach in
analysing and evaluating data and information as well as views and interpretations
to develop academic and social skills such as critical thinking, communicating effectively both in visual and verbal
forms- cooperating with others, taking initiatives and providing leadership in solving others', problems
to develop qualities clustered around the personal, social, moral, national and spiritual values that make a person
humane and socially effective.
