Term: 3^rd Term

WEEK 6: Capacity

Class: Primary 4

Age: 9 years

Duration: 40 minutes of 5 periods

Subject: Mathematics

Topic: Capacity

SPECIFIC OBJECTIVES:

At the end of the lesson, pupils should be able to:

INSTRUCTIONAL PROCEDURES

PERIOD 1 and 2:

STEP	TEACHER’S ACTIVITY	PUPIL’S ACTIVITY
STEP 1 – INTRODUCTION	Introduces multiplication of liquid capacity by whole numbers using practical examples (e.g., “If one bottle holds 2 liters, how much will 4 bottles hold?”).	Pupils share examples of when they multiply capacity in real life (e.g., filling multiple containers).
STEP 2 – EXPLANATION	Explains how to multiply liquid capacity by whole numbers (e.g., 2 L × 4 = 8 L).	Pupils practice multiplying capacity values with teacher guidance.
STEP 3 – DEMONSTRATION	Demonstrates multiplication of liquid capacity with visual aids and measuring containers.	Pupils practice multiplying liquid capacities in pairs.
STEP 4 – EXERCISES	Provides practice exercises for pupils to multiply different liquid capacities (e.g., 3 L × 5, 1.5 L × 4).	Pupils work individually to solve the multiplication problems.

PERIOD 3 and 4:

STEP	TEACHER’S ACTIVITY	PUPIL’S ACTIVITY
STEP 1 – INTRODUCTION	Reviews the concept of multiplication and transitions to division of liquid capacity.	Pupils recall multiplication and discuss how division is the opposite.
STEP 2 – EXPLANATION	Explains how to divide liquid capacity by whole numbers (e.g., 6 L ÷ 3 = 2 L).	Pupils learn how to divide liquid capacities through examples.
STEP 3 – DEMONSTRATION	Demonstrates division of liquid capacity using visual aids and containers.	Pupils practice division of liquid capacities in pairs or groups.
STEP 4 – EXERCISES	Provides division exercises for pupils to solve (e.g., 12 L ÷ 4, 6 L ÷ 2).	Pupils solve division problems on their own and with guidance.

PERIOD 5:

STEP	TEACHER’S ACTIVITY	PUPIL’S ACTIVITY
STEP 1 – INTRODUCTION	Discusses real-life situations where we multiply and divide liquid capacity (e.g., filling multiple tanks, sharing liquid among friends).	Pupils discuss real-life scenarios where they multiply or divide liquid capacity.
STEP 2 – EXPLANATION	Explains how to apply multiplication and division of capacity in real-life scenarios.	Pupils practice applying multiplication and division of capacity to solve word problems.
STEP 3 – DEMONSTRATION	Solves practical capacity problems using multiplication and division.	Pupils solve practical capacity problems in groups or individually.
STEP 4 – EXERCISES	Provides word problems on multiplying and dividing capacity (e.g., “If you have 3 liters of juice and want to share it equally among 5 people, how much will each person get?”).	Pupils solve real-life word problems in pairs or groups.

EVALUATION:

If you have 2 liters of juice and you divide it equally among 4 people, how much does each person get?
If a jug contains 5 liters of milk and you need to fill 5 bottles, how much milk will each bottle hold?

CLASSWORK:

A tank holds 10 liters of water. If it is divided into 2 equal parts, how much water will be in each part?
You have 15 liters of oil. If you fill 3 bottles, how much oil is in each bottle?

ASSIGNMENT:

A bottle holds 4 liters of water. How many 2-liter bottles can be filled?
You have 20 liters of liquid, and you need to distribute it equally into 4 containers. How much will be in each container?

CONCLUSION:

Recap the multiplication and division of capacity in real-life scenarios (e.g., sharing liquids, filling containers).
Emphasize the importance of understanding capacity in everyday life, especially in cooking, cleaning, and other daily activities.
Encourage pupils to continue practicing multiplying and dividing liquid capacities.

EVALUATION FOR THE WHOLE WEEK:

Group exercises on practical applications of capacity.
