**Syllabus **

**Chapter 1: Number systems**

The numbers arranged in a set of real numbers is called a Number system. Real numbers are the numbers that can be characterized on a number line. For example, one million is equal to ten lakhs. i.e. 1,000,000=10,00,000

**Chapter 2: Factors and Multiples**

Factors- The exact divisor of the number is called its factors. Multiples- Multiplying a natural number by a number, then a multiple is obtained.

In this chapter, we will study the multiples and factors of the numbers. For example, 8= 1 x 8= 4 x 2. Hence 1, 2, 4, 8 are the multiples of 8. Therefore, 8 is a multiple of 1, 2, 4, and 8.

**Chapter 3: Whole Numbers**

Whole numbers are a set of numbers that can be written without a fractional component. In short, we can say, an integer. It is represented as “W.” For example, {0, 3, 5,…, -135} are whole numbers. The smallest whole number is 0.

Some facts about whole numbers are- All-natural numbers are also whole numbers

**Chapter 4: Integers**

Integers are the whole numbers that can be positive, negative, or zero but not a fractional component and decimal. For example, 1, 2, 3, 0, -3, -4, -5, etc.

**Chapter 5: Fractions**

A fraction represents a numerical value of a whole in parts. For example, an apple is cut into 4 parts in which a child takes one part, then the fraction becomes ¾.

**Chapter 6: Simplification**

Simplification refers to simplifying complicated expressions into a simple or direct answer. BODMAS is explained in this chapter with its formula and application. For example, one will solve 23+ 7 x 3= 30 x 3= 90 which is wrong. It should be solved as 23+ 7 x 3= 23+ 21= 44.

**Chapter 7: Decimals**

Decimals are the fractional components that are represented in the form of decimals (points). One fruit is divided into 6 parts, and each part can be written as 1/6, then it can be represented as 0.1 in the form of decimal notation.

**Chapter 8: Algebraic Expressions**

Algebraic expressions are sets of variables, mathematical operations, and constants. For example, Variables have different values, so mathematical operations like addition, multiplication, subtraction, and division can be performed on them.

**Chapter 9: Linear equations in one variable **

The equations that can be represented in ax+b = 0 forms are called linear equations in one variable.

**Chapter 10: Ratio, Proportion, and Unitary method**

A ratio is the comparison of a particular two numbers by division. Finding the value of a unit and then the values of other units are called the Unitary method. For example, the cost of 4 cans of juices is 200, then what is the cost of 6 cans of juices?

**Chapter 11: Line segment, ray, and line**

A line is drawn by two points. A ray is a mixture of line and segment which has an infinite terminating end.

**Chapter 12: Parallel lines**

Lines are said to be parallel when two lines are in the same plane and do not intersect with each other.

**Chapter 13: Angles and their measurements**

The measurement between two arms is called angles. Primarily, there are 6 types – acute angle, obtuse angle, right angle, reflex angle, full angle, and straight angle.

**Chapter 14: Constructions**

Constructions include drawing different geometrical structures. For example, draw a ray AB. Keep the protector with its central point at C and draw an edge at point B.

**Chapter 15: Polygons**

The polygons are made up of straight lines and connected by lines. Examples of polygons are triangles, pentagons, quadrilaterals, hexagons, etc.

**Chapters 16: Triangles**

In this chapter, triangles are classified as groups on the basis of their sides and angles.

**Chapter 17: Quadrilaterals**

A polygon with four sides and four vertices is called quadrilaterals. Rectangle, the square, is an example of quadrilaterals.

**Chapter 18: Circles**

The circle is a closed curve which is not a polygon. Ball, bangles, coins are examples of circles.

**Chapter 19: Three-dimensional shapes**

Three-dimensional shapes are the shapes that can be picked up, moved around, and touched. For example, Cubes, prisms, spheres. Cones, cylinders, etc.

**Chapter 20: Two-dimensional reflection symmetry**

Reflection symmetry is the symmetry concerning reflection. In two-dimensional reflection symmetry, a line or an axis of symmetry is formed.

**Chapter 21: Concept of perimeter and area **

The measurement of the length of the outline or a boundary of an object or shape. The perimeter can be determined by adding up all the sides. Whereas area is the space occupied by the object/shape, which is measured in square inches.

**Chapter 22: Data handling **

Data handling includes a collection of numbers to get information. This collection can be performed in various ways; tally marks are one of them, and another way is the pictograph method.

**Chapter 23: Pictograph**

Pictograph is used to represent information in the form of objects or pictures. It is the study of numerical data in the form of pictographs.

**Chapter 24: Bar graph**

The bar graph is a type of graphical representation of its length proportional to its value. They can either be determined in a horizontal or vertical method. For example, a graphical representation of the population scale of different years can be drawn in a bar graph format.
