Topic: Finding Positions, Directions, and Using Conventional Signs and Symbols
Sub-topic: Types of North and Introduction to Conventional Signs and Symbols

 

Learning Objectives

By the end of the lesson, students should be able to:

  1. Distinguish between Magnetic, True, and Grid North.
  2. Define conventional signs and symbols.
  3. Identify the types of signs and symbols: point, line, literal, pictorial, and color.

 

Previous Knowledge

Students already know:
• Compass points and angular bearings
• Map orientation basics
• Using grid references to locate positions

 

Instructional Materials

  • Textbook: Geography for Senior Secondary Schools
    • Teaching aids: Compass, protractor, topographical maps, colored markers
    • Students' notebooks and writing materials

Lesson Development – ABC Model

A – Anticipation (Warm-up / Starter)

Time: 5–10 minutes

Activity:
The teacher will ask:
• “Have you noticed how a compass needle points slightly differently depending on where you are?”
• “What do you think cartographers use to represent roads, rivers, or mountains on maps?”

Teacher’s Role: Record responses, clarify misconceptions about types of north and map symbols.

Learner’s Role:
• Share experiences with using compass and maps.
• Participate actively in discussion.

 

B – Building Knowledge (Main Lesson Body)

Time: 25–30 minutes

Teacher’s Role:
• Explain Types of North:

  • True North: The direction towards the geographic North Pole.
  • Magnetic North: The direction towards the Earth’s magnetic pole.
  • Grid North: The north indicated by the vertical lines on a map grid.
    • Explain Conventional Signs and Symbols:
  • Definition: Signs or symbols used on maps to represent real-world features.
  • Types:
    • Point symbols (e.g., schools, churches)
    • Line symbols (e.g., rivers, roads)
    • Literal symbols (e.g., names or letters)
    • Pictorial symbols (e.g., drawings for landmarks)
    • Color symbols (e.g., blue for water, green for forest)
      • Demonstrate examples on maps and charts.

Learners’ Activities (Expanded):
• Identify True, Magnetic, and Grid North on classroom maps.
• Match different map symbols to their real-world features.
• Work in pairs to create a mini-map using various conventional symbols.

Assessment Checks:
• Ask students to explain differences between the three types of north.
• Observe accuracy in identifying and using conventional signs.

Notes (Expanded & Detailed):

  • True North: Always points to geographic North Pole, used in navigation.
  • Magnetic North: Changes over time; compass needles align with it.
  • Grid North: Helps align maps with grid references.
  • Conventional Signs: Essential for interpreting maps efficiently; reduces clutter.
  • Importance: Facilitates navigation, planning, and communication of spatial information.

 

C – Consolidation (Conclusion & Assessment)

Time: 5–10 minutes

Summary:
• Teacher asks students to recall:

  • Differences between True, Magnetic, and Grid North
  • Types of conventional symbols and their examples

Evaluation Method (Expanded):
• Exit slip/quiz:

  • Identify the type of north indicated by a compass.
  • Match symbols to features on a sample map.
    • Teacher provides oral feedback and corrects misconceptions.

Assignment (Expanded):
• Draw a small map of your neighborhood using at least 10 conventional signs and indicate True, Magnetic, and Grid North.
• Label the types of north and explain why each is important in map reading.

 

Differentiation / Inclusive Strategies

  • Struggling Learners: Use a simplified map with fewer symbols for practice.
    • Advanced Learners: Create a larger thematic map using all types of symbols and different norths.
    • Students with Disabilities: Provide tactile maps or printed colored charts for better understanding.

 

Teacher’s Reflection (After Class)

  • What worked well?
  • What needs improvement?
  • Students’ engagement level: □ High □ Medium □ Low
    • Next steps: Introduce the importance, uses, and limitations of conventional signs and symbols in Week 5.
