CBSE Syllabus For Class 9 Maths Unit 1: Number Systems
Real Numbers (18 Periods)

 Review of representation of natural numbers, integers, rational numbers on the number line. Representation of terminating / nonterminating recurring decimals on the number line through successive magnification. Rational numbers as recurring/ terminating decimals. Operations on real numbers.
 Examples of nonrecurring/nonterminating decimals. Existence of nonrational 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.
 Existence of for a given positive real number and its representation on the number line with geometric proof.
 Rationalization (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 the learner to arrive at the general laws.)
NCERT CBSE Syllabus For Class 9 Maths Unit 2: Algebra
Polynomials (23 Periods)
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. Factorization of ax^{2} + 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:
(x + y + z)^{2} = x^{2} + y^{2} + z^{2} + 2xy + 2yz + 2zx
(x ± y)^{3} = x^{3} ± y^{3} ± 3xy (x ± y)
x^{3 }+ y^{3 }+ z^{3 }– 3xyz = (x + y + z) (x^{2} + y^{2} + z^{2} – xy – yz – zx) and their use in factorization of polynomials.
 Linear Equations in Two Variables (14 Periods)
Recall of linear equations in one variable. Introduction to the equation 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 lie on a line. Graph of linear equations in two variables. Examples, problems from real life, including problems on Ratio and Proportion, and algebraic and graphical solutions being done simultaneously.
CBSE Syllabus For Class 9 Maths Unit 3: Coordinate Geometry
 Coordinate Geometry (6 Periods)
The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations, plotting points in the plane.
CBSE Syllabus For Class 9 Maths Unit 4: Geometry
Introduction to Euclid’s Geometry (6 Periods)
History – Geometry in India and Euclid’s geometry. Euclid’s method of formalizing observed phenomenon 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.
Lines and Angles (13 Periods)

 (Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180^{o}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 180^{o}.
 (Motivate) If a side of a triangle is produced, the exterior angle so formed is equal to the sum of the two interior opposite angles.
Triangles (20 Periods)
 (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) 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 (motivate) its converse.
Area (7 Periods)
Review the concept of area, recall the area of a rectangle.
 (Prove) Parallelograms on the same base and between the same parallels have the same area.
 (Motivate) Triangles on the same (or equal base) base and between the same parallels are equal in area.
Circles (15 Periods)
Through examples, arrive at the definition of a circle and related conceptsradius, circumference, diameter, chord, arc, secant, sector, segment, subtended angle.
 (Prove) Equal chords of a circle subtend equal angles at the center and (motivate) its converse.
 (Motivate) The perpendicular from the center of a circle to a chord bisects the chord, and conversely, the line drawn through the center of a circle to bisect a chord is perpendicular to the chord.
 (Motivate) There is one and only one circle passing through three given noncollinear points.
 (Motivate) Equal chords of a circle (or of congruent circles) are equidistant from the center (or their respective centers) and conversely.
 (Prove) The angle subtended by an arc at the center 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.
