NCERT Sampurna Hal Ganit Kaksha - 9

Once William Paul Thurston said, “Mathematics is not about numbers, equations, computations, or algorithms: it is about Understanding.” It is a constant effort of NCERT that it puts on its textbooks to promote clearer understanding of concepts in every student. As important as theoretical study is, Practical study is also essential to prove theories into realities. The freshly updated edition of “LABORATORY MANUAL- MATHEMATICS” for class IX has been designed as a complete package to understand all the relevant mathematical experiments in a simple, lucid and interactive manner. Strictly based on CBSE guidelines, each activity includes theory to give deep insights into each concept, formula, term & definition, etc. Viva Voce questions, Notes, Suggested Activities, Applications, etc. are accumulated to make concepts clearer in accordance with the curriculum. Along with the Activities, all the projects listed in NCERT Lab Manual have also been properly covered. This book serves as a step-by-step guide for conducting experiments in such a way that students will not need to refer to any other book for explanations of the concepts.
