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.
