Semester: 1
Period: 1
Week: 2
School Name: ___________________________
Teacher’s Name: _________________________
Subject: Geography
Grade Level: 12
Date: Week 2
Lesson Duration: 45 minutes
Week & Period: Week 2, Period 1
Topic: Finding Positions, Directions, and Using Conventional Signs and Symbols
Sub-topic: Locating Positions using Grid References
Learning Objectives
By the end of the lesson, students should be able to:
- Determine positions using grid references on maps.
- Apply grid systems to locate features on a map.
- Interpret grid references for practical map reading.
Previous Knowledge
Students already know:
• Lines of latitude and longitude
• Basic map features and symbols
Instructional Materials
- Textbook: Geography for Senior Secondary Schools
• Teaching aids: Topographical maps, atlas, ruler, projector
• Students' notebooks and writing materials
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Activity:
The teacher will ask the class:
• “How can we pinpoint the location of a river or a hill on a map without latitude and longitude?”
• “Have you ever used the grid on a sports field or graph paper to locate points?”
The teacher will record responses on the board.
Teacher’s Role: Guide brainstorming, clarify the concept of grids on maps.
Learner’s Role:
• Share prior experiences with grids.
• Participate in discussion and respond verbally.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher’s Role:
• Explain what a grid reference is (4-figure, 6-figure).
• Demonstrate how to read and plot grid references on a map.
• Show examples of locating towns, rivers, and hills using grid references.
• Conduct guided practice exercises.
Learners’ Activities (Expanded):
• Identify grid squares for given features.
• Plot features using 4-figure and 6-figure grid references.
• Work in pairs to quiz each other on given coordinates.
Assessment Checks:
• Ask students to give a 6-figure grid reference for a selected feature.
• Observe accuracy during practice exercises.
Notes (Expanded & Detailed):
- Grid Lines: Vertical (eastings) and horizontal (northings) lines forming squares.
- 4-Figure Reference: Identifies a square (e.g., 2135).
- 6-Figure Reference: Pinpoints exact location within a square (e.g., 213456).
- Uses: Locating towns, rivers, roads, hills accurately on topographic maps.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary:
• Teacher asks students to recall:
- Difference between 4-figure and 6-figure grid references
- How to locate a feature using eastings and northings
Evaluation Method (Expanded):
• Exit slip/quiz:
- Give the 6-figure grid reference for a river on the map.
- Identify the square containing a specific hill.
• Teacher reviews responses and provides feedback.
Assignment (Expanded):
• Using a topographical map, locate 5 features using 4-figure and 6-figure references.
• Practice converting between 4-figure and 6-figure grid references.
Differentiation / Inclusive Strategies
- Struggling Learners: Provide partially completed grid maps.
• Advanced Learners: Assign complex features requiring multiple 6-figure references.
• Students with Disabilities: Use digital interactive maps with zoom features.
Teacher’s Reflection (After Class)
- What worked well?
- What needs improvement?
- Students’ engagement level: □ High □ Medium □ Low
• Next steps: Reinforce grid references with exercises next week; introduce compass points and bearings.
