Term: 2nd Term

Week 11
Class: Primary 5
Age: 10 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Project on Types of Angles and Types of Triangles

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

  1. Identify different types of angles (acute, obtuse, right, straight, reflex).
  2. Identify different types of triangles (equilateral, isosceles, scalene).
  3. Work collaboratively in groups to create models of angles and triangles.
  4. Apply the properties of angles and triangles in real-life situations.

INSTRUCTIONAL TECHNIQUES:

  • Project-based learning
  • Group activities
  • Hands-on approach
  • Interactive discussions

INSTRUCTIONAL MATERIALS:

  • Ice-cream sticks
  • Markers
  • Cardboards
  • Glue
  • Rulers
  • Protractors

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:
PRESENTATION

Step

Teacher’s Activity

Pupil’s Activity

STEP 1 – INTRODUCTION

Introduces the concept of angles and triangles, explaining the different types and their properties.

Pupils listen and ask questions about angles and triangles.

STEP 2 – EXPLANATION

Explains how to classify angles and triangles based on their sides and angles.

Pupils take notes on the different types of angles and triangles.

STEP 3 - DEMONSTRATION

Demonstrates how to create models of angles and triangles using ice-cream sticks and glue.

Pupils observe and assist in creating models of angles and triangles.

STEP 4 - GROUP WORK

Divides pupils into groups and instructs them to use ice-cream sticks, markers, and glue to create different types of angles and triangles.

Pupils work in groups to create models of angles and triangles.

NOTE (On the Board):

  • Types of Angles:
    • Acute angle: less than 90°
    • Right angle: exactly 90°
    • Obtuse angle: greater than 90° but less than 180°
    • Straight angle: exactly 180°
    • Reflex angle: greater than 180°
  • Types of Triangles:
    • Equilateral triangle: all sides equal
    • Isosceles triangle: two sides equal
    • Scalene triangle: no sides equal

EVALUATION:

  • Ask pupils to identify and classify angles and triangles in real-life objects or drawings.
  • Review each group’s model and check for accuracy in angle and triangle formation.
    CLASSWORK:
  • Complete a worksheet identifying different types of angles and triangles in various images.
    ASSIGNMENT:
  • Create a poster that shows different types of angles and triangles, labeling each one.

CONCLUSION:
The teacher commends pupils for their creativity in completing the project and encourages them to practice identifying angles and triangles in their environment.
