Term: 3rd Term

Week 3

Class: Primary 6
Age: 11 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Polygons

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

  1. Define the term "polygon" and identify its properties.
  2. Name various polygons (e.g., triangle, quadrilateral, pentagon, hexagon, heptagon, and octagon).
  3. Classify polygons based on the number of sides.
  4. Draw any kind of polygon, including their names.
  5. Draw lines of symmetry for various polygons.

INSTRUCTIONAL TECHNIQUES:
• Demonstration
• Group activities
• Hands-on practice (drawing polygons and symmetry)
• Use of teaching aids (charts, drawing materials)
• Interactive discussions

INSTRUCTIONAL MATERIALS:
• Chart with examples of polygons
• Drawing materials (pencil, ruler, compass)
• Worksheets for exercises
• Flashcards with polygon names and properties

 

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:

PRESENTATION

Step

Teacher's Activity

Pupil's Activity

STEP 1 – INTRODUCTION

Introduces the term "polygon," explaining that a polygon is a closed two-dimensional shape with straight sides. Gives examples of common polygons (triangle, quadrilateral, pentagon, etc.).

Pupils listen and ask questions for clarification.

STEP 2 – EXPLANATION

Defines and explains polygons with a focus on the number of sides, using examples: triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), heptagon (7 sides), octagon (8 sides).

Pupils observe and take notes on the classification of polygons.

STEP 3 - DEMONSTRATION

Demonstrates how to draw various polygons on the board (triangle, quadrilateral, pentagon, hexagon, heptagon, octagon) and labels each shape.

Pupils watch and try to replicate the drawing of polygons.

STEP 4 - NOTE TAKING

Explains the naming and properties of each polygon, as well as how to draw them.

Pupils take notes on the names and properties of each polygon.

NOTE (On the Board):

  • Polygon: A closed figure with straight sides.
  • Examples of polygons:
    • Triangle: 3 sides
    • Quadrilateral: 4 sides (square, rectangle, kite, rhombus, trapezium)
    • Pentagon: 5 sides
    • Hexagon: 6 sides
    • Heptagon: 7 sides
    • Octagon: 8 sides

EVALUATION:
• Ask pupils to name different polygons and their number of sides.
• Ask pupils to draw different polygons and label them correctly.

CLASSWORK:
• Draw the following polygons: Triangle, Square, Pentagon, Hexagon, and Octagon. Label each with the correct number of sides.

ASSIGNMENT:
• Draw and label a quadrilateral and a heptagon.

CONCLUSION:
The teacher commends the pupils for their participation and encourages them to practice drawing various polygons.

 

PERIOD 3 and 4:

PRESENTATION

Step

Teacher's Activity

Pupil's Activity

STEP 1 – INTRODUCTION

Recaps the definition of a polygon and introduces lines of symmetry. Discusses the concept of symmetry in polygons.

Pupils recall previous lessons on polygons and listen to the introduction of symmetry.

STEP 2 – EXPLANATION

Explains the concept of lines of symmetry in polygons. Demonstrates how to draw lines of symmetry for various polygons (e.g., square, equilateral triangle, hexagon, etc.).

Pupils observe and practice drawing lines of symmetry for the given polygons.

STEP 3 - DEMONSTRATION

Demonstrates lines of symmetry for specific polygons on the board (e.g., 4 lines of symmetry in a square, 2 lines in an isosceles triangle).

Pupils follow along and practice drawing lines of symmetry for polygons on their paper.

STEP 4 - NOTE TAKING

Pupils take notes on the definition and importance of lines of symmetry in polygons.

Pupils take notes and ask questions for further understanding.

NOTE (On the Board):

  • Lines of Symmetry: A line that divides a shape into two identical halves.
  • Example:
    • Square: 4 lines of symmetry
    • Equilateral Triangle: 3 lines of symmetry
    • Rectangle: 2 lines of symmetry
    • Hexagon: 6 lines of symmetry
    • Isosceles Triangle: 1 line of symmetry

EVALUATION:
• Ask pupils to identify the number of lines of symmetry in various polygons.
• Ask pupils to draw and label the lines of symmetry for different polygons on the board.

CLASSWORK:
• Draw and label lines of symmetry for the following polygons: square, rectangle, triangle, pentagon, hexagon.

ASSIGNMENT:
• Find a real-life object that has lines of symmetry and explain how many lines of symmetry it has.

CONCLUSION:
The teacher congratulates the pupils for their effort and encourages them to explore symmetry in their surroundings.

 

SUMMARY OF LESSON:
This week, the pupils learned about polygons, including how to identify and classify them based on the number of sides. They also learned how to draw these shapes and identify their lines of symmetry. The lesson was interactive, allowing pupils to practice drawing and understanding the properties of polygons.
