Lesson Plan of Units of Volume

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.
