Arihant Laboratory Manual Mathematics for Class 9

The Central Board of Secondary Education (CBSE) conducts practical examination for Class IX students. This laboratory manual has been designed to help Class IX students prepare for Activities, Projects and Viva Voce for Mathematics. The present book for CBSE Class IX Mathematics Activities, Projects and Viva Voce has been divided into two parts namely Activities (Term I & Term II) and List of projects covering the syllabi of Term I and Term II. The Activities (Term I) section covers activities like To construct a square root spiral, to represent some irrational numbers on the number line, To verify exterior angle property of a triangle, to verify experimentally the different criteria for congruency of triangles using triangle cut outs, etc. whereas the Activities (Term II) covers To find the formula for the area of a trapezium experimentally, To verify that the triangles on the same base & between the same parallels are equal in area, To verify that the angles in the same segment of a circle are equal, To verify that the opposite angles of a cyclic quadrilateral are supplementary, To form a cuboid & find the formula for its surface area experimentally, To form a cone from a sector of a circle, To obtain the formula for the surface area of a sphere, etc. The Projects section covers To develop Heron’s formula for area of a triangle, Extensions of Phythagoras Theorem, Magic Squares, Mathematical designs & patterns, Ramanujan number, Mathematical crosswords, Application of geometry in day-to-day life, Golden rectangle & golden ratio, Knowledge & classification of solid figures with respect to surface areas & volumes, etc. As the book cum laboratory manual covers all the experiments and viva voce, it for sure will help Class IX students prepare their best for CBSE Class IX Mathematics Practical Examination.
