Lesson Plan of Units of Volume
Subject Mathematics
Grade III
Students` Learning Outcomes
 Read standard units of volume (liter and Milliliter) including abbreviations.
 Measure and write standard units of volume including abbreviations.
Information for Teachers
 Volume is the measure of amount of space taken up /occupied by an object.
 The space within a container is known as its capacity.
 Basic unit of volume is liter abbreviated as “l”, the unit smaller than liter is milliliter abbreviated as “ml”.
 1000milliliter is equal to 1 liter.
 While teaching the lesson, the teacher should also consult textbook at all the steps where and when applicable.
Material / Resources
Writing board, chalk/marker, duster, pointer/stick, empty glass / soft drink bottles, measuring cups / jar spoons, textbook
Introduction
 Show to student’s empty milk cartoon or soft drink bottle and ask them to read the unit measure written on it.
 Refers to their previous learning and ask following questions from students.

 What is the unit to measure liquid?
 Which one is bigger? Liter or milliliter
 How many milliliters are there in 1 liter?

Development
Activity 1
 Show some containers with the units of volume written on them.
 Ask students to note down all the units mentioned on the containers.
 Ask following questions to the students and facilitate them to find the correct answer to these questions by giving examples from everyday life activities.
Q 1: What is the basic unit of volume? (Expected answer may be as; Liter)
Q 2: What is the abbreviation for liter? (Expected answer may be as; “L”)
Q 3: What is the unit smaller than liter? (Expected answer may be as; Milliliter)
Activity 2
 Divide the class into two groups.
 Provide each group four empty bottles of 250ml, one 1liter and two 500ml.
 Ask students to fill the one liter bottle with water first using 250ml empty bottle and then using 500ml bottle.
 Repeat this activity by filling the 500 ml bottles with 250 ml bottle.
 Ask following questions from the students.


 What is the capacity of smallest bottle? (Expected answer may be as; 250 milliliter)
 What is the capacity of the largest bottle? (Expected answer may be as;1 Liter)
 How many bottles of 250 ml are required to fill one liter bottle? (Expected answer may be as; 4)
 How many bottles of 500 ml are required to fill one liter bottle? (Expected answer may be as; 2)
 How milliliters are there in one liter? (Expected answer may be as; 1000)
 How many ml in 2l, 3l, 4l, and so on? (Expected answer may be as; 2000, 3000, 4000)

Activity 3
 Show a measuring cylinder and a 500 ml beaker to the students and ask them to observe these.
Q1: What instrument do we use to measure the volume of liquids?
Q2: What measurement is written on the given instruments?
Q3: What does “l” and “ml” mean?
 Introduce the units of volume while discussing student`s response against the above questions.
Sum up / Conclusion
 Volume is the measure of amount of space taken up / occupied by an object. The space within a container is known as its capacity.
 Basic unit of volume is liter abbreviated as “l”, the unit smaller than liter is milliliter abbreviated as “ml”.
 1000 milliliter is equal to 1 liter.
Assessment
 What are the standard units for measuring volume of liquids? (liter / milliliter)

 What is the smaller unit of measuring liquids?
 What is the larger unit of measuring liquids?

Follow up
 Ask students to measure the capacity of different containers at their home by using empty bottles of 250ml, 500ml, and one liter.
 Ask the students to solve the questions given in the textbook in their notebooks as individual work.
 Ask the students to solve the questions given in the textbook.
