## CBSE Class 4 Mathematics:

Math is highly important for the growing children and they must be properly trained to solve all the possible problems in their syllabus. Apart from the regular patterns such as addition, subtraction, multiplication and division, Class 4 covers various topics such as geometrical figures, fraction, decimal, etc. It is a known fact that the student who has strong knowledge in math is capable to solve any kind of problems even in other subjects. CBSE Class 4 syllabuses is prepared by experienced teachers who have designed the subjects according to the student’s learning ability.

Now let us check the detailed syllabus of CBSE Class 4 Mathematics below:

• Numbers:

This is a next level of numerical system which covers the topics such as Rounding of numbers, Indian and International systems, predecessor and successor number, comparing numbers, even odd numbers and so on.

Examples:

1. The Roman numeral for 49 is __________
• XLIX
• L
• XLVI

1. Write the numbers in standard expanded form:
• 45634

1. Arrange the following in descending order:
• -9, 0,-4, 5,3,1

• Arithmetic operations on numbers:

Word problems based on Addition, subtraction, multiplication and division are covered in this section. These problems will help the students to solve day-to-day real life problems while dividing cakes among friends, shopping, saving and many more.

Examples:

1. The smallest 5-digit odd number ______
• 1002
• 1233
• 1001

1. Subtract the following numbers:
• 888888-177777 =?

1. A factory produces 2050 dolls per day. How many dolls are produced in 45 days?

1. 25 % _ = 1

• Fractions, Decimals:

Introduction to Fractions are given in the CBSE Class 3. Thus now, fractions concept cover dividing shapes in half’s, quarters, mixed and advanced word problems in fractions.

In CBSE Class 4, Decimal section is introduced which covers the topics like reading the decimals and place value, conversion and operations of decimals, etc., This gives a basic understanding for the students of Class 4 that the decimal point goes between units and tenths.

The best example for understanding the concept of fraction and decimal is below:

Fraction: 45/100

Decimal: 0.45

Examples:

1. Arrange the following fractions in ascending order:
• 5/12, 3/12,1/12,4/12

1. If 25 out of 45 students are girls in a school, then the decimal for the part of girls in the school are:

• Time and Date:

Time and date is a very important concept in everyday life. Students must have a strong understanding of time and date formats, AM and PM difference, reading the clock, handling the time, etc. The concept which are covered in “Time and Date” are reading the clock and knowing the correct time, time taken for a task, 24 hour format, etc.,

Examples:

1. 6 hours after 8.45 P.M is ______

1. Asha leaves home at 7.30 A.M and returns home at 4.15 P.M. How long she has stayed out?

1. Half past 7 A.M and quarter past 10 P.M?

Answer: 7.30 A.M and 10.15 P.M

• Money:

Just like time and date concept, the concept of money is also very important for day-to-day activities. Understanding the profit and loss in a sale, knowing the current balance are most important concepts in everyday life.

Examples:

1. How many rupees are there in 4560 paise?

1. The price of color pencil box was Rs.58 on February which was priced up to Rs.98 within next two months. What is the difference in the price increase?

• Geometry:

Geometry is an important and interesting subject of mathematics. In our day-to-day life we come across various objects in different shapes. Also, such objects shapes differ according to the position we look at it. Thus, these positions are named as front view, top view, side view and bottom view. Every object is different in different positions.

Examples:

1. ________ has two end points?

1. The radius of a circle is 5 cm. Find out its diameter?

1. Sunil walks around a triangular garden with sides 16m, 23m and 45m. Find out the distance he covers if he walks around it for 4 times.

• Circle:

This is part of Geometrical concept, which covers the topics such as drawing circle, radius of the circle, making circle designs using the compass, centre of circle and so on. The main specialty of a circle when compared to other geometrical figures is it does not have any edges or corners. The distance between the centre of the circle and its circumference is said to be radius.

Examples:

1. Pictorial representations of circles are given to find out the diameter, radius of it.

• Perimeter and Area:

These are used to measure the size of an object. Perimeter is the total boundary size of an object whereas Area is the total surface covered by the object. Perimeter is measured in terms of meter.

The topics which are covered under this section are calculating the exact boundary of given objects, uneven objects and curved shape, Circle boundary and word problems based on perimeter and area of an object.

Examples:

1. Examples are based on pictorial representation of a triangle, rectangle or square. Students are asked to find out the perimeter and area of the object by giving the sizes of the sides.

• Measurement of Length, Mass and Capacity:

This is a very common concept and it covers calculating distance between two objects, converting meter to kilo meter, milli meter, etc., Along with the standard unit meter, in CBSE Class 4, other measuring units such as Miles, yard, feet and inches are also taught. Similarly, measuring mass in terms of kgs and grams are also covered in CBSE Class 4 syllabus. In addition to this, introduction to the problems of jugs and mugs, litters and milli litters are covered under the topic of Measurement of capacity.

Examples:

1. Divide the following:
• 25km 96m divided by 2

1. Convert 7678 kg into quintal:

1. Convert the 25 l 75 ml in ml

• Designs and patterns-Building with bricks:

This is a concept which is a part of Geometry as it mostly covers the concept of Cuboid. Bricks are in the shape of cuboid and math is going to be a fun with these building bricks. Topics covered in this section are Drawing a brick and different wall patterns, shapes and sizes of the bricks, process of building bricks, etc.,

Examples:

1. A brick has ______ edges
• 13 edges
• 8 edges
• 12 edges
