Term: 2nd Term

Week 9

Class: Primary 5
Age: 10 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Volume and Capacity

SPECIFIC OBJECTIVES:

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

  1. Use units to find the volume of cubes and cuboids.
  2. Apply the formula for the volume of a cuboid.
  3. Understand the relationship between liters and cubic centimeters.
  4. Convert cubic centimeters to liters and vice versa.
  5. Solve quantitative aptitude problems related to volume and capacity.

INSTRUCTIONAL TECHNIQUES:

  • Demonstration
  • Group activities
  • Problem-solving approach
  • Use of teaching aids (e.g., models, charts)
  • Interactive discussions

INSTRUCTIONAL MATERIALS:

  • Chart with volume formulas
  • Cubes and cuboids (models)
  • Markers, whiteboard, and erasers
  • Worksheets for exercises
  • Real-life objects (e.g., water containers, boxes)

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 – INTRODUCTION

Introduces the concept of volume and explains the units used to measure volume.

Pupils listen and ask questions about the units used for volume.

STEP 2 – EXPLANATION

Explains the formula for calculating the volume of cubes and cuboids.

Pupils take notes on the formulas for volume.

STEP 3 - DEMONSTRATION

Demonstrates how to calculate the volume of cubes and cuboids using models.

Pupils observe the teacher’s demonstration and practice with their own models.

STEP 4 - PRACTICE

Assigns problems involving the calculation of volume for given cubes and cuboids.

Pupils calculate the volume individually.

NOTE (On the Board):

  • Formula for Volume:
    • Cube: V=a³
    • Cuboid: V=l×w×h
  • Example:
    • Cube with side 4 cm:

V=4³ =64 cm³

    • Cuboid with length 5 cm, width 3 cm, and height 2 cm:

V=5×3×2=30 cm³

EVALUATION:

  • Ask pupils to solve a set of problems calculating the volume of cubes and cuboids.

CLASSWORK:

  • Calculate the volume of 5 cubes and cuboids with different dimensions.

ASSIGNMENT:

  • Write a short paragraph explaining how volume is used in real-life situations and solve 2 problems involving volume.

CONCLUSION: The teacher congratulates the pupils on their progress and encourages them to keep practicing.

 

PERIOD 3 and 4:

PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 – INTRODUCTION

Recaps the previous lesson on volume and introduces the relationship between liters and cubic centimeters.

Pupils recall the concept of volume and listen attentively.

STEP 2 – EXPLANATION

Explains the relationship between liters and cubic centimeters: 1 liter=1,000 cm³

Pupils take notes and ask questions.

STEP 3 - DEMONSTRATION

Demonstrates converting cubic centimeters to liters and vice versa.

Pupils practice conversion using examples on the board.

STEP 4 - PRACTICE

Assigns problems on converting between cubic centimeters and liters.

Pupils solve the conversion problems on their own.

NOTE (On the Board):

  • Conversion:
    • 1 liter=1,000 cm³
    • Example: Convert 2,500 cm³ to liters.

2,500 cm³ =2,500÷1,000=2.5 liters

EVALUATION:

  • Ask pupils to solve conversion problems on the board.

CLASSWORK:

  • Solve conversion problems and complete worksheets.

ASSIGNMENT:

  • Convert 3,000 cm³ to liters and solve 3 problems on volume.

CONCLUSION

The teacher concludes by reviewing the key points on volume and capacity and encourages pupils to practice at home.
