Degree of a polynomial; constant, linear, quadratic, cubic polynomials; monomials, binomials, trinomials. Factors and multiples. Zeros of a polynomial/equation. State and motivate the Remainder Theorem with examples and analogy to integers. Statement and proof of the Factor Theorem. Factorization of ax² + bx + c, a ≠ 0 where a, b, c are real numbers and of cubic polynomials using the Factor Theorem.
2.) Linear Equations In Two Variables
Recall of linear equations in one variable. Introduction to equations in two variables. Focus on linear equations of the type ax + by + c = 0. Prove that a linear equation in two variables has infinitely many solutions, and justify their being written as ordered pairs of real numbers. Plotting them and showing that they seem to lie on a line. Graph of linear equations in two vairables. Examples, problems from real life, including, problems on Ratio and Proportion and with algebraic and graphical solutions being done simultaneously.
UNIT III : COORDINATE GEOMETRY
Coordinate Geometry
The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations, plotting points in the plane.
UNIT IV : GEOMETRY
1.)Lines And Angles
i.)(Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180º and the converse.
ii.)(Prove) If two lines intersect, the vertically opposite angles are equal.
iii.)(Motivate) Results on corresponding angles, alternate angles, interior angles when a transversal intersects two parallel lines.
iv.)(Motivate) Lines, which are parallel to a given line, are parallel.
v.)(Prove) The sum of the angles of a triangle is 180º.
vi.)(Motivate) If a side of a triangle is produced, the exterior angle so formed is equal to the sum of the two interiors opposite angles.
2.)Triangles
i.)(Motivate) Two triangles are congruent if any two sides and the included angle of one triangle is equal to any two sides and the included angle of the other triangle (SAS Congruence).
ii.)(Prove) Two triangles are congruent if any two angles and the included side of one triangle is equal to any two angles and the included side of the other triangle (ASA Congruence).
iii.)(Motivate) Two triangles are congruent if the three sides of one triangle are equal to three sides of the other triangle (SSS Congruence).
iv.)(Motivate) Two right triangles are congruent if the hypotenuse and a side of one triangle are equal (respectively) to the hypotenuse and a side of the other triangle (RHS Congruence).
v.)(Prove) The angles opposite to equal sides of a triangle are equal.
vi.)(Motivate) The sides opposite to equal angles of a triangle are equal.
vii.)(Motivate) Triangle inequalities and relation between ‘angle and facing side’ inequalities in triangles.
3.)Quadrilaterals
i.)(Prove) The diagonal divides a parallelogram into two congruent triangles.
ii.)(Motivate) In a parallelogram, opposite sides are equal and conversely.
iii.)(Motivate) In a parallelogram, opposite angles are equal and conversely.
iv.)(Motivate) A quadrilateral is a parallelogram if a pair of its opposite sides is parallel and equal.
v.)(Motivate) In a parallelogram, the diagonals bisect each other and conversely.
vi.)(Motivate) In a triangle, the line segment joining the mid points of any two sides is parallel to the third side and (motivate) its converse.
4.)Area
Review concepts of area. Recall area of a triangle.
i.)(Prove) Parallelograms on the same base and between the same parallels have the same area.
ii.)(Motivate) Triangles on the same base and between the same parallels are equal in area.
5.)Circles
Through examples, arrive at definitions of circle related concepts, radius, circumference, diameter, chord, arc, subtended angle.
i.)(Prove) Equal chords of a circle subtend equal angles at the centre and (motivate) its converse.
ii.)(Motivate) The perpendicular from the centre of a circle to a chord bisects the chord and conversely, the line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.
iii.)(Motivate) There is one and only one circle passing through three given noncollinear points.
iv.)(Motivate) Equal chords of a circle (or of congruent circles) are equivalent from the centre and conversely.
v.)(Prove) The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.
vi.)(Motivate) Angles in the same segment of a circle are equal.
vii.)(Motivate) If a line segment joining two points subtends equal angles at two other points lying on the same side of the line containing the segment, the four points lie on a circle.
viii.)(Motivate) The sum of either pair of opposite angles of a cyclic quadrilateral is 180° and its converse.

Mean, median, mode of ungrouped data.
2.)Probability
History, repeated experiments and observed frequency approach to probability. Focus is on empirical probability (A large amount of time to be devoted to group and to individual activities to motivate the concept; the experiments to be drawn from reallife situations, and from examples used in the chapter on statistics).
