### CBSE Class 9 Maths Marks Distribution Chapter-wise 2023

CBSE provides unit-wise marks distribution only. If you go through the syllabus document, you will find that there are six units this year and CBSE has provided marks distribution for each unit separately.

- Number Systems will carry 10 marks. The chapter Real Numbers is part of the unit number systems. If you check the CBSE class 9 maths syllabus 2022-23 PDF file, you will get to know that some topics are revised this year.
- Algebra has the second highest weightage. It has two chapters polynomials and linear equations. The total weightage to Algebra is 20 marks.
- Coordinate Geometry is a small unit with only one chapter. It bears only 4 marks.
- Geometry is the highest weightage in class 9 Maths syllabus 2022-23. Overall 27 marks are allotted to this unit because it has 5 chapters.
- Mensuration covers Areas, Surface Areas and Volumes only. This unit is revised and reduced drastically. Total of 13 mark questions will come from this unit.
- The last unit Statistics and Probability has only one chapter left. It is Statistics. The other chapter Probability is fully deleted.

**UNIT I: NUMBER SYSTEMS**

**REAL NUMBERS (18 Periods)**- Review of representation of natural numbers, integers and rational numbers on the number line. 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 {tex}\sqrt{2}, \sqrt{3}{/tex} 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.
- Rationalization (with precise meaning) of real numbers of the type {tex}\frac{1}{a+b \sqrt{x}}{/tex} and {tex}\frac{1}{\sqrt{x}+\sqrt{y}}{/tex} (and their combinations) where x and y are natural number 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 learner to arrive at the general laws.)

**UNIT II: ALGEBRA**

**POLYNOMIALS (26) Periods**Definition of a polynomial in one variable, with examples and counter examples. Coefficients of a polynomial, terms of a polynomial and zero polynomial.

Motivate and State the Remainder Theorem with examples. Statement and proof of the Factor Theorem. Factorization of ax

^{2}+ bx + c, a {tex}\ne{/tex} 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 {tex}\pm{/tex} y)^{3 }= x^{3}{tex}\pm{/tex} y^{3}{tex}\pm{/tex} 3xy(x {tex}\pm{/tex} y)

x^{3}{tex}\pm{/tex} y^{3 }= (x {tex}\pm{/tex} y)(x^{2}{tex}\pm{/tex} xy + y^{2}

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 (16) Periods**Recall of linear equations in one variable.

**Class 9 Maths Question Paper Design**

Question paper design lets you know about the typology of questions and mark distribution. In the CBSE class 9 Maths syllabus 2022-23 there are two major parts

- Theory Paper – 80 Marks
- Internal Assessment – 20 Marks

**Typology of Questions in 9th Maths**

There are three main types of questions in the 9th class maths syllabus for 2022 – 2023. These are

- Remembering and Understanding – 43 Marks
- Applying – 19 Marks
- Analysing, Evaluating and Creating – 18 Marks

As this typology is based on Bloom’s taxonomy, we can clearly conclude that around 50% of questions will be easy and direct questions based on the formula. The next 25% will be of moderate difficulty level and the last 25% will need a bit higher thinking level.

**The student will get 3 hours to solve this 80 marks question paper. **

S.No | Typology of Questions | Total Marks | % Weightage (approx) |
---|---|---|---|

1. | Remembering: Exhibit memory of previously learned material by recalling facts, terms, basic concepts, and answers.Understanding: Demonstrate understanding of facts and ideas by organizing, comparing, translating, interpreting, giving descriptions, and stating main ideas | 43 | 54 |

2. | Applying: Solve problems to new situations by applying acquired knowledge, facts, techniques and rules in a different way. | 19 | 24 |

3. | Analysing: Examine and break information into parts by identifying motives or causes. Make inferences and find evidence to support generalizationsEvaluating: Present and defend opinions by making judgments about information, validity of ideas, or quality of work based on a set of criteria.Creating: Compile information together in a different way by combining elements in a new pattern or proposing alternative solutions | 18 | 22 |

Total | 80 | 100 |

**Class 9 Maths Internal Assessment**
