Demo Teaching Presentation on Mathematics

Introduction

• Presenter: Maika Milikeran
• Course: Bachelor in Elementary Education
• Topic: Mathematics (Grade 5)
• Objective: Teach about polygons, focusing on properties of regular and irregular polygons.

Opening

1. Greeting
   • Good afternoon to the students.
   • Expresses happiness about the students' well-being.
2. Prayer
   • Invites a student (Christine) to read a prayer.
   • Prayer focuses on gratitude for health and learning opportunities.
3. Attendance Check
   • Checks attendance and asks students to tidy up the classroom.

Lesson Introduction

• Engagement Activity: Observing Surroundings
  • Students look around the room to identify objects with three or more sides.
  • Examples given by students:
    • Book (square shape, 4 sides)
    • Picture frame (rectangle shape, 4 sides)

Main Topic: Polygons

1. Definition
   • Polygon: From Greek "poly" (many) and "gon" (angles).
   • Formed by combining line segments.
2. Types of Polygons
   • Equilateral Triangle: 3 sides, 3 angles.
   • Quadrilateral: 4 sides, 4 angles.
   • Pentagon: 5 sides, 5 angles.
   • Hexagon: 6 sides, 6 angles.
   • Heptagon: 7 sides, 7 angles.
   • Octagon: 8 sides, 8 angles.
   • Nonagon: 9 sides, 9 angles.
   • Decagon: 10 sides, 10 angles.

Properties of Polygons

1. Regular Polygons
   • Definition: All sides and angles are equal.
   • Examples:
     • Pentagons and Octagons discussed in detail.
2. Irregular Polygons
   • Definition: Sides are not equal.
   • Example: A pentagon with unequal sides shown.

Activity: Classifying Polygons

• Students classify polygons as regular or irregular based on examples presented.
• Sets of polygons analyzed by students:
  • Set A: Equal sides and angles (Regular).
  • Set B: Unequal sides (Irregular).

Summary of Learning

• Definitions reiterated:
  • What is a polygon?
  • What is a regular polygon?
  • Students give examples of both types.

Final Activity & Assignment

1. Final Activity: Classifying polygons shown in pictures.
   • Students identify and classify each polygon.
2. Assignment:
   • Draw 5 regular and 5 irregular polygons, using various materials.
