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.
