IMO Class 3 Chapter 5: Length

Mathematics is one of the most important and prominent subjects to learn. It is a fundamental discipline that deals with the study of numbers, quantities, and shapes, and their relationships and operations. Mathematics is used in various fields, including science, engineering, finance, and economics, and it plays a crucial role in our everyday lives.

Learning mathematics is essential for several reasons. Firstly, it helps develop critical thinking and problem-solving skills, which are essential for success in various fields. Secondly, it provides a foundation for learning other subjects, such as science, engineering, and computer science. Thirdly, it helps us make sense of the world around us and enables us to understand and solve practical problems in our daily lives.

International Math Olympiad (IMO) is a thriving platform that provides an excellent opportunity for school students to showcase their mathematical skills and compete at an international level which is conducted by School Connect Online. The IMO aims to promote mathematical knowledge, problem-solving skills, teamwork, and cultural exchange among students from different countries. The competition consists of challenging mathematical problems that require creative thinking and problem-solving skills, and it is conducted over two days.

IMO Class 3 Chapter 5: Length Detailed Notes

In this day and age, knowing the Capacity, Time, Length, Weight, and Temperature is critical.


The process of obtaining a number that determines the amount of something is known as measurement.

  • What age are you?
  • How much weight do you have?
  • What is your height?

We need to measure in order to answer the questions above.

  • You must estimate the time to determine your age.
  • You must weigh yourself in order to determine your weight.
  • You must estimate your height in order to understand how tall you are (length).


Time is the continuous continuity of events. Time can be measured in seconds, minutes, hours, days, weeks, months, and years.

We are encouraged to estimate time by using a clock and a calendar.


The volume of an element that makes up a thing is described as its weight. Holding the weight of a thing is what it means to estimate its weight.

Weighing can be done in grams, kilograms, or pounds.


The length of something is the value covered from one end to the opposite on the largest side.


A capacity model represents how much volume a thing can hold. Liters and gallons are used to measure capacity.


A substance’s temperature is a measure of how hot or cold it is. Temperature is expressed in degrees Celsius, Fahrenheit, and Kelvin.
