PROCEDURE :-

Start the session by asking the questions related to the quantities around us and start differentiating the quantities whether they have magnitude or direction or both. Now introduce the topic vector step by step as follows.

S.No.	TOPICS AND EXPLANATION
1	Introduction of vectors, definition of scalar and vector quantities and making the different lists of scalar and vector quantities around us. Scalar: The quantities which has only magnitude are called scalar quantities, for example distance. Vector: The quantities which has  magnitude and direction both are called vector quantities, for example displacement.
2	Explain the different types of vectors, like equal, unit, zero, negative, parallel , co-initial and collinear vectors. Give their definitions with examples.
3	Explain the method of finding the position vector of a point, by giving some examples and explain the method of finding the magnitude of a vector.
4	Define direction angles, cosines and direction ratios. Explain the concept  by taking an example of a general vector. Direction angles: These are the angles made by the vector with the positive direction of the axis. Direction cosines: cosines of the direction angles are called direction cosines. Direction ratios: The terms which are proportional to the direction cosines are called direction ratios.
5	Explain the triangle law and parallelogram law of vector addition, also explain the different properties of vector addition.
6	Explain the method of multiplication of a vector with a scalar.
7	Explain the components of vectors along x-axis, y-axis, z-axis and explain the formation of the vector in terms of components.
8	Explain the method of finding a vector joining two points.
9	Explain the section formula for internal and external division and then explain the mid-point formula.
10	Product of two vectors : Scalar or dot product of two vectors and their important properties.
11	Explain the concept of projection of a vector on a line and
12	Explain the method of finding the area of triangle and parallelogram by using vector algebra. Also explain the Lagrange’s identities.
13	Explain the scalar triple product of three vector. Three vectors are coplanar if their scalar triple product is
