UNIT I: NUMBER SYSTEMS

  1. REAL NUMBERS

Review of representation of natural numbers, integers, and rational numbers on the number line. Representation of terminating / non-terminating recurring decimals on the number line through successive magnification. Rational numbers as recurring/ terminating decimals. Operations on real numbers.

Examples of non-recurring/non-terminating decimals. Existence of non-rational numbers (irrational numbers) such as and their representation on the number line. Explaining that every real number is represented by a unique point on the number line and conversely, viz. every point on the number line represents a unique real number.

Definition of nth root of a real number.

Rationalisation (with precise meaning) of real numbers of the type (and their combinations) where x and y are natural numbers and a and b are integers.

Recall of laws of exponents with integral powers. Rational exponents with positive real bases (to be done by particular cases, allowing learners to arrive at the general laws.)

UNIT II: ALGEBRA

  1. POLYNOMIALS

Definition of a polynomial in one variable, with examples and counterexamples. Coefficients of a polynomial, terms of a polynomial and zero polynomial. Degree of a polynomial. Constant, linear, quadratic and cubic polynomials. Monomials, binomials, trinomials. Factors and multiples. Zeros of a polynomial.

Motivate and State the Remainder Theorem with examples. Statement and proof of the Factor Theorem. Factorisation of 𝑎𝑥2+𝑏𝑥+𝑐,𝑎≠0ax2+bx+c,a≠0 where a, b and c are real numbers, and of cubic polynomials using the Factor Theorem.

Recall of algebraic expressions and identities. Verification of identities and their use in the factorisation of polynomials.

  1. LINEAR EQUATIONS IN TWO VARIABLES

Recall linear equations in one variable. Introduction to the equation in two variables.

Focus on linear equations of the type ax+by+c=0. Explain 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 lie on a line. Graph of linear equations in two variables. Examples are 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. INTRODUCTION TO EUCLID’S GEOMETRY (Not for assessment)

History - Geometry in India and Euclid’s geometry. Euclid’s method of formalising observed phenomena into rigorous Mathematics with definitions, common/obvious notions, axioms/postulates and theorems. The five postulates of Euclid. Equivalent versions of the fifth postulate. Showing the relationship between axiom and theorem, for example:

(Axiom) 1. Given two distinct points, there exists one and only one line through them.

(Theorem) 2. (Prove) Two distinct lines cannot have more than one point in common.

  1. LINES AND ANGLES

(Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180O and the converse.

(Prove) If two lines intersect, vertically opposite angles are equal.

(Motivate) Results on corresponding angles, alternate angles, interior angles when a transversal intersects two parallel lines.

(Motivate) Lines that are parallel to a given line are parallel.

(Prove) The sum of the angles of a triangle is 180O.

(Motivate) If a side of a triangle is produced, the exterior angle formed is equal to the sum of the two interior opposite angles.

  1. TRIANGLES

(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).

(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).

(Motivate) Two triangles are congruent if the three sides of one triangle are equal to three sides of the other triangle (SSS Congruence).

(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).

(Prove) The angles opposite to equal sides of a triangle are equal.

(Motivate) The sides opposite to equal angles of a triangle are equal.

(Motivate) Triangle inequalities and relation between ‘angle and facing side’ inequalities in triangles.

  1. QUADRILATERALS

(Prove) The diagonal divides a parallelogram into two congruent triangles.

(Motivate) In a parallelogram, opposite sides are equal and conversely.

(Motivate) In a parallelogram, opposite angles are equal and conversely.

(Motivate) A quadrilateral is a parallelogram if a pair of opposite sides are parallel and equal.

(Motivate) In a parallelogram, the diagonals bisect each other and conversely.

(Motivate) In a triangle, the line segment joining the midpoints of any two sides is parallel to the third side and in half of it and (motivates) its converse.

  1. AREA

Review concept of area, recall area of a rectangle.

(Prove) Parallelograms on the same base and between the exact parallels have equal areas.

(Motivate) Triangles on the same base (or equal bases) and between the same parallels are equal in area.

  1. CIRCLES

Through examples, arrive at the definition of a circle and related concepts-radius, circumference, diameter, chord, arc, secant, sector, segment, subtended angle.

(Prove) Equal chords of a circle subtend equal angles at the centre and (motivate) its converse.

(Motivate) The perpendicular from the centre of a circle to a chord bisects the chord and conversely, the line is drawn through the centre of a circle to bisect a chord is perpendicular to the chord.

(Motivate) There is one and only one circle passing through three given non-collinear points.

(Motivate) Equal chords of a circle (or of congruent circles) are equidistant from the centre (or their respective centres) and conversely.

(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.

(Motivate) Angles in the same segment of a circle are equal.

(Motivate) If a line segment joining two points subtends an equal angle at two other points lying on the same side of the line containing the segment, the four points lie on a circle.

(Motivate) The sum of either pair of the opposite angles of a cyclic quadrilateral is 180° and its converse.

  1. CONSTRUCTIONS

Construction of bisectors of line segments and angles of measure 60o, 90o, 45o etc., equilateral triangles.

Construction of a triangle given its base, sum/difference of the other two sides and one base angle.

The Construction of a triangle of a given perimeter and base angles.

UNIT V: MENSURATION

Surface areas and volumes of cubes, cuboids, spheres (including hemispheres) and right circular cylinders/cones.

UNIT VI: STATISTICS & PROBABILITY

  1. STATISTICS

Introduction to Statistics: Collection of data, presentation of data— tabular form, ungrouped/grouped, bar graphs, histograms (with varying base lengths), frequency polygons. Mean, median and mode of ungrouped data.

  1. PROBABILITY

History, Repeated experiments and observed frequency approach to probability.

The focus is on empirical probability. (A large amount of time is devoted to group labelled fibres and individual activities to motivate the concept; the experiments to be drawn from real-life situations and examples used in the chapter on statistics).
