CBSE Lab Manual Class 9 Maths creates mathematical awareness in students. It inculcates skill building, positive attitude and learning by doing experiences among students, so that they get acquainted with various mathematics branches such as Algebra, Geometry, Mensuration, Trigonometry, Coordinate Geometry, Statistics and Probability, etc. Here, we have provided complete details on the CBSE Class 9 Maths Laboratory Manual, including the laboratory’s activities and mathematical equipment. Class 9 students will learn concepts and verify many mathematical facts and properties using models, measurements and other activities by going through them.
Maths is a compulsory subject at the Secondary Stage. Access to quality mathematics education is the right of every child. CBSE Class 9 Maths practicals and activities engage students in using abstractions to establish relationships, see structures, reason out things and find the truth or falsity of statements. Therefore, CBSE has introduced the Class 9 Maths practicals in the curriculum by providing access to laboratory manuals. The Maths Lab Manual will nurture students’ ability to explore and seek solutions to problems not only in the academic areas but also in daily life.

Equipments for CBSE Class 9 Mathematics Laboratory
The mathematics laboratory requires various materials and oddments such as strings and threads, cellotape, white cardboard, hardboard, needles and pins, drawing pins, sandpaper, pliers, screwdrivers, rubber bands of different colours, gummed papers and labels, squared papers, plywood, scissors, saw, paint, soldering, solder wire, steel wire, cotton wool, tin and plastic sheets, glazed papers, etc. Besides these, some equipment like mathematical instruments, calculators, computers, books, journals, mathematical dictionaries, etc. are required in the laboratory. We have provided below the list of suggested instruments/models that will help students perform their activities.
Mathematical instrument set (Wooden Geometry Box for demonstration containing rulers, set-squares, divider, protractor and compasses), geometry boxes, metre scales of 100 cm, 50 cm and 30 cm, measuring tape, diagonal scale, clinometer, calculators, computers including related software, etc.
- Number line
- Geoboards – rectangular, circular and isometric
- Models for verifying the following identities:
(i) (a + b)2 = a2 +2ab + b2
(ii) (a – b)2 = a2 – 2ab + b2
(iii) a2 – b2 = (a – b) (a + b)
(iv) k (a + b + c) = ka+ kb + kc
(v) (a + b)3 = a3 + b3 + 3a2b + 3ab2
(vi) (a – b)3 = a3 – b3 – 3a2b + 3ab2
(vii) a3 + b3 = (a + b)3 – 3ab (a + b)
(viii) a3 – b3 = (a – b)3 + 3ab (a – b)
