Preface, The Textbook Society, Karnataka has been engaged in producing new textbooks according, to the new syllabi which in turn are designed on NCF - 2005 since June 2010. Textbooks are, prepared in 12 languages; seven of them serve as the media of instruction. From standard, 1 to 4 there is the EVS, mathematies and 5th to 10th there are three core subjects namely, mathematics, science and social science., NCF - 2005 has a number of special features and they are:, connecting knowledge to life activities, learning to shift from rote methods, enriching the curriculum beyond textbooks, learning experiences for the construction of knowledge, making examinations flexible and integrating them with classroom experiences, caring concerns within the democratic policy of the country, make education relevant to the present and future needs., softening the subject boundaries-integrated knowler, the child is the constructor of knowledge, and the joy of learning, The new books are produced based on three fundame, |approaches namely., Constructive approach, Spiral approach and, ted approach., The learner is encouraged to think, engage in activities, master skills and competencies., The materials presented in these books are, examination oriented in their nature. On the other hand, they, ntegrated with values. The new books are not, help the learner in the total development of his/her personality, thus help him/her become a, healthy member of a healthy society and a productive citizen of this great country, India., Mathematics is essential in the, moving away from complete calculations, construction of a framework of concepts, relate, mathematics to real life experiences and cooperative learning., Many students have a maths phobia and in order to help them overcome this phobia, jokes,, puzzles, riddles, stories and games have been included in textbooks. Each concept is introduced, through an activity or an interesting story at the primary level.

Chairperson's note to teachers, This First Standard Mathematics Textbook is prepared according to, the revised syllabus based on NCF, 2005. The basic feature highlighted, in NCF (2005) and seriously adopted in this textbook is that "The child is, the constructor of his/her own knowledge". The focus in this textbook is, on experiential learning which is based on both hands on and minds, on activities., The introduction of new mathematics syllabus and textbooks should, be always backed up by a wealth of activities, illustrations and problems, through which children can play and explore mathematics. There is, no better guidance than well chosen illustrations that appeal to the, intuition and focus the imagination and through which the child can, construct his/her own mathematical knowledge. Such self-discovery, leads to a much deeper understanding and a confidence in the subject,, which the children can never forget and upon which he/she can build, further., The First Standard Mathematics Textbook is designed keeping all, the above mentioned facts in view and also the intellectual development, of children at that age level. Considering the point that the children, are at concrete operation stage during this age, a large store of, pictures are provided, which represent real life objects and situations., As mathematics is a very challenging and vibrant subject connected to, the real world at every level, these illustrations help children to connect, mathematics with real life situations. They also provide opportunities, for children to indulge in challenging and exciting tasks of discovery, and creativity as well,, Mathematics teaching should be child-centred and also learning-, centred. It is the responsibility of the teachers to generate interest and, stimulate enthusiasm in the subject. Teachers are expected to play, the role of facilitators and create constructive learning environments, with the help of illustrations suggested in this textbook and many more, similar to or beyond them., Hope that the material presented in this textbook will trigger the, imagination, thinking and reasoning skills in children and support, them to construct meaningful mathematical knowledge. Constructive, suggestions for further improvement of this textbook are always, welcome., 3

About the Revision of Textbooks, Honourable Chief Minister Sri Siddaramaiah who is also the Finance Minister of, Karnataka, in his response to the public opinion about the new textbooks from standard, I to X, announced, in his 2014-15 budget speech of constituting an expert-committee,, to look into the matter. He also spoke of the basic expectations there in, which the, textbook experts should follow: "The textbooks should aim at inculcating social equality,, moral values, development of personality, scientific temper, critical acumen, secu, rism, and the sense of national commitment", he said., Later, for the revision of the textbooks from class 1 to X, the, Education constituted twenty seven committees and passed an order on 24-11-2014., The committees so constituted were subject and class-wise and were in accordance with, the standards prescribed. Teachers who are experts in matters, bartment of, subjects and syllabi, were in the committees., TB, There were already many complaints, and analyses about the textbooks.

In the same order, it was said that the completely, revised textbooks could be put to force from 2017-18 instead of 2016-17., to the responsible committees, Many selfinspired individuals and institutions, listing out the wrong information and, mistakes there in the text, had sent them to the Education Minister and to the Textbook, Society. They were rectified. Before rectification we had exchanged ideas by arranging, debates. Discussions had taken place with Primary and Secondary Education Teachers', Associations. Questionnaires were administered among teachers to pool up opinions., Separate meetings were held with teachers, subject inspectors and DIET Principals., Analytical opinions had been collected. To the subject experts of science, social science,, mathematics and languages, textbooks were sent in advance and later meetings were, held for discussions. Women associations and science related organistation were also, invited for discussions. Thus, on the basis of all inputs received from various sources,, the textbooks have been revised where ever necessary., Another very important aspect has to be shared here. We constituted three expert, V
