Term: 3^rd Term

Week 2

Class: Primary 6
Age: 11 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Angles, Lines, and Bearings

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

Explain the meaning of angles and give some classroom examples.
Identify different types of angles.
Measure angles in degrees using clocks (30º, 45º, 60º, 90º, 120º, etc.).
Explain the term "line" and identify some lines in the classroom.
Measure different types of lines accurately.
Identify various types of angles and lines.

INSTRUCTIONAL TECHNIQUES:
• Demonstration
• Group activities
• Use of teaching aids (protractors, rulers, charts)
• Interactive discussions

INSTRUCTIONAL MATERIALS:
• Protractors
• Rulers
• Whiteboard and markers
• Flashcards with angle types
• Worksheet for exercises

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces the concept of angles and explains the different types of angles (acute, right, obtuse, etc.).	Pupils listen attentively and ask questions about the types of angles.
STEP 2 - EXPLANATION	Explains how to measure angles using protractors and clocks.	Pupils watch and practice measuring angles using protractors.
STEP 3 - DEMONSTRATION	Demonstrates measuring angles on a clock face, explaining angles like 30º, 45º, and 90º.	Pupils practice measuring these angles using clocks in the classroom.
STEP 4 - NOTE TAKING	Provides a summary of angle types and measuring methods.	Pupils take notes on angle types and how to measure angles.

NOTE (On the Board):
• Types of Angles:

Acute: Less than 90º
Right: Exactly 90º
Obtuse: Between 90º and 180º
Reflex: Greater than 180º
• Measuring Angles:
Use a protractor to measure angles.
Example: 30º, 45º, 60º, 90º, 120º.

EVALUATION:
• Ask pupils to identify the type of angle from flashcards.
• Review the steps for measuring angles.

CLASSWORK:
• Measure angles using protractors: 30º, 45º, 60º, 90º.
• Identify types of angles from given examples.

ASSIGNMENT:
• Measure five angles in the classroom or at home and record them.

CONCLUSION:
The teacher commends the pupils for their engagement and encourages them to practice measuring different angles.

PERIOD 3 and 4:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Recaps the previous lesson on angles and introduces the concept of lines.	Pupils recall angle types and participate in a short discussion.
STEP 2 – EXPLANATION	Explains the concept of lines and their different types: straight, curved, parallel, and perpendicular.	Pupils listen and take notes on the types of lines.
STEP 3 - DEMONSTRATION	Demonstrates examples of each type of line in the classroom.	Pupils observe and identify lines in the classroom.
STEP 4 - NOTE TAKING	Explains how to measure the length of lines using rulers.	Pupils take notes and practice measuring lines using rulers.

NOTE (On the Board):
• Types of Lines:

Straight: A line with no curves.
Curved: A line that bends continuously.
Parallel: Two lines that never meet.
Perpendicular: Two lines that meet at a 90º angle.

EVALUATION:
• Ask pupils to identify types of lines in their surroundings.
• Provide examples for pupils to practice measuring lines.

CLASSWORK:
• Measure lines using rulers.
• Identify parallel and perpendicular lines in the classroom.

ASSIGNMENT:
• Find and record examples of different types of lines at home or outside.

CONCLUSION:
The teacher commends the pupils for their participation and encourages them to continue identifying lines in their environment.

PERIOD 5:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces the concept of bearings and explains its use in navigation.	Pupils listen attentively and engage in a brief discussion.
STEP 2 – EXPLANATION	Explains how bearings are measured in degrees, with reference to the compass.	Pupils take notes on bearings and compass directions.
STEP 3 - DEMONSTRATION	Demonstrates how to use a compass to measure bearings.	Pupils observe and practice measuring bearings with a compass.
STEP 4 - NOTE TAKING	Provides examples of bearings and how they are used.	Pupils take notes and ask questions for clarification.

NOTE (On the Board):
• Bearings: Measured in degrees from north, usually in a clockwise direction.
• Example: A bearing of 90º means east, 180º means south.

EVALUATION:
• Ask pupils to identify bearings using a compass.
• Provide examples for practice.

CLASSWORK:
• Measure bearings using a compass and record the direction.

ASSIGNMENT:
• Find the bearings for different locations in the classroom or at home.

CONCLUSION:
The teacher encourages the pupils to practice using bearings for navigation and acknowledges their efforts.

Summary of Lesson:

This week, pupils will explore the concepts of angles, lines, and bearings, including how to identify, measure, and use them in practical situations. They will practice using protractors and rulers for angles and lines, and they will learn to measure bearings using a compass.
