ICSE Mathematics Class 9 Latest Syllabus 2024-25

Go Back

There will be one paper of two and a half hours duration carrying 80 marks and Internal Assessment of 20 marks.

Certain questions may require the use of Mathematical tables (Logarithmic and Trigonometric tables).

The solution of a question may require the knowledge of more than one branch of the syllabus.

1. Pure Arithmetic

Rational and Irrational Numbers

Rational, irrational numbers as real numbers, their place in the number system. Surds and rationalization of surds. Simplifying an expression by rationalizing the denominator. Representation of rational and irrational numbers on the number line.

Proofs of irrationality of

$$\sqrt{2},\sqrt{3}\sqrt{5}$$

2. Commercial Mathematics

Compound Interest

(a) Compound interest as a repeated Simple Interest computation with a growing Principal. Use of this in computing Amount over a period of 2 or 3 years.

Handling positive, fractional, negative and “zero” indices

Simplification of expressions involving various exponents

(b) Laws of Logarithms and their uses.

Expansion of expression with the help of laws of logarithms

$$\text{e.g.}\space y = \frac{a^{4}×a^{2}}{c^{3}}$$

log y = 4 log a + 2 log b – 3 log c etc.

4. Geometry

(i) Triangles

(a) Congruency: four cases: SSS, SAS, AAS, and RHS. Illustration through cutouts. Simple applications.

(b) Problems based on:

  • Angles opposite equal sides are equal and converse.
  • If two sides of a triangle are unequal, then the greater angle is opposite the greater side and converse.
  • Sum of any two sides of a triangle is greater than the third side.
  • Of all straight lines that can be drawn to a given line from a point outside it, the perpendicular is the
    shortest.

Proofs not required

(c) Mid-Point Theorem and its converse, equal intercept theorem

(i) Proof and simple applications of midpoint theorem and its converse.

(ii) Equal intercept theorem: proof and simple application.

(d) Pythagoras Theorem

Area based proof and simple applications of Pythagoras Theorem and its converse.

(ii) Rectilinear Figures

(a) Proof and use of theorems on parallelogram.

  • Both pairs of opposite sides equal (without proof).
  • Both pairs of opposite angles equal.
  • One pair of opposite sides equal and parallel (without proof).
  • Diagonals bisect each other and bisect the parallelogram.
  • Rhombus as a special parallelogram whose diagonals meet at right angles.
  • In a rectangle, diagonals are equal, in a square they are equal and meet at right angles.

(b) Constructions of Polygons

Construction of quadrilaterals (including parallelograms and rhombus) and regular hexagon using ruler and
compasses only.

(c) Proof and use of Area theorems on parallelograms:

  • Parallelograms on the same base and between the same parallels are equal in area.
  • The area of a triangle is half that of a parallelogram on the same baseand between the same parallels.
  • Triangles between the same base and between the same parallels are equal in area (without proof).
  • Triangles with equal areas on the same bases have equal corresponding altitudes

(iii) Circle:

(a) Chord properties

  • A straight line drawn from the centre of a circle to bisect a chord which is not a diameter is at right angles to the chord.
  • The perpendicular to a chord from the centre bisects the chord (without proof).
  • Equal chords are equidistant from the centre.
  • Chords equidistant from the centre are equal (without proof).
  • There is one and only one circle that passes through three given points not in a straight line.

(b) Arc and chord properties:

  • If two arcs subtend equal angles at the centre, they are equal, and its converse.

Internal Assessment

A minimum of two assignments are to be done during the year as prescribed by the teacher.

Suggested Assignments

  • Conduct a survey of a group of students and represent it graphically - height, weight, number of family members, pocket money, etc.
  • Planning delivery routes for a postman/milkman.
  • Running a tuck shop/canteen.
  • Study ways of raising a loan to buy a car or house, e.g. bank loan or purchase a refrigerator or a television set through hire purchase.
  • Cutting a circle into equal sections of a small central angle to find the area of a circle by using the formula A = πr2.
  • To use flat cutouts to form cube, cuboids and pyramids to obtain formulae for volume and total
    surface area.
  • Draw a circle of radius r on a ½ cm graph paper, and then on a 2 mm graph paper. Estimate the area enclosed in each case by actually counting the squares. Now try out with circles of different radii. Establish the pattern, if any, between the two observed values and the theoretical value (area = π r2 ). Any modifications?
