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.
