PREFACECBSE always believe in Global Trends of Educational Transformation. The CBSEcurriculum gets its lead from National Curriculum Framework – 2005 and Right to Freeand Compulsory Education Act – 2009. As said by John Holt “We learn to do something bydoing it. There is no other way” is very true and this is the reason why CBSE hasMathematics Practical's as a part of curriculum of class IX and X. So that students canperform what they learn how Mathematics has been applied in our daily life.The Mathematics Lab Manual for Classes IX & X has been written so as tosupplement the need of the students to prepare for lab work and learn mathematicspractical during the entire year. Performing mathematics practically also generates interestin students towards mathematics.This Lab Manual includes all activities and experiments as specified in latest CBSEcurriculum. Practical based questions have been included in the form of Multiple ChoiceQuestions (MCQs) and Short Answer Type Questions. At the end of every activity VivaVoce questions have been given for extra practice. Group Activities provide will helpstudents to learn team work. Projects have been added to facilitate collective efforts andextension of learning to real life. Each activity/experiment comprises of theoreticalconcepts which provides brief description about activities.This book is strictly according to the latest CBSE guidelines, and contains morethan sufficient viva voce questions and brief description of each activity/experiment,which help students in practicing and completing the lab work. All activities andexperiments are always checked twice and tried to make precise. Practically, this bookprovides students everything they need to learn during their lab work. Since we believe incontinuous improvement, hence this book has been written with accuracy as well asupdated as per CBSE guidelines and reviewed at different tiers by panel of experts.We are sure that this book will serve as a perfect teaching guide for the teachers andgood lab manual for the students.
