This Master Class is to clear the misconceptions which 90% of the students from all the boards face in the topic Mensuration for 2D & 3D objects in mathematics. The weightage of this topic in majority of the national and international educational boards varies from 15 to 30 % of total syllabus. The topic is very scoring provided students can visualize the concepts and have thier basic Mathematica skills in place. My master class will help them to enjoy the topic with a new sense of freshness by learning the techniques and by acquiring the skills at the end of the session. They must carry a blank sheet of A4 paper, pencil, notebook, a Rubic Cube ( optional), a borosil water drinking glass ( optional), a glass bangle ( optional), a conical birthday cap( optional). Class VIII to X students of any board, mathematics teachers who are new to the profession, parents who wish to have a peek a boo towards the learning style of thier children are most welcome to enjoy the master class.
