Lesson Structure

Starter Activity (10 minutes) – "Find the Treasure"

1. Engagement Hook: Display an enlarged Ordnance Survey-style map on the board with a pirate treasure box marked at an unknown location.
2. Question Prompt: Ask students, “If I wanted to tell you exactly where the treasure is, how could I do it without pointing?”
3. Pair Discussion: Students discuss in pairs for 2 minutes, then share ideas with the class. Guide them toward the concept of grid references.
4. Introduction of Learning Objective: Explain that today they will master the skill of using 4-figure grid references to become expert map readers.

Main Lesson (35 minutes)

Step 1: Understanding the Map Grid (10 minutes)

• Explain that maps are divided into a grid to help locate places easily.
• Introduce the concept of eastings (vertical grid lines) and northings (horizontal grid lines).
• Use a giant grid on the whiteboard to demonstrate:
  • Eastings come first (like reading left to right)
  • Northings come second (like climbing up the map)
• Write an example (e.g., 34, 52) and guide students to find the corresponding square on the large map.

Step 2: Practical Application – Map Challenge (15 minutes)

• Hand out Ordnance Survey-style maps to students in pairs.
• Give them a set of 4-figure grid references and challenge them to find the locations.
• Example references:
  • 34 52 – School
  • 36 49 – River bend
  • 31 51 – Church
• After 5 minutes, review answers together by marking locations on the board.

Step 3: Partner Challenge – Mystery Locations (10 minutes)

• Each pair writes three 4-figure grid references and swaps with another pair.
• Their task is to find the locations based on the given references.
• Quick discussion: What strategies helped them?

Plenary (15 minutes) – "Ultimate Explorer Quiz"

1. Quick-fire Questions:
   • Why do eastings come first?
   • What happens if you swap the two numbers?
   • How is this skill useful in real life?
2. Reflection – “Where Could This Help You?”
   • Students jot down real-world applications (e.g., hiking, finding addresses, military navigation).
   • Share a few responses with the class.
3. Exit Ticket:
   • Students write one thing they learnt today and one question they still have.

Resources Needed

✅ Large printed or digital map with a visible grid
✅ Whiteboard & markers
✅ Printed or digital Ordnance Survey-style maps
✅ Worksheets with grid reference challenges

---

Differentiation Strategies

• For Higher Ability Students: Introduce 6-figure grid references for an extra challenge.
• For Lower Ability Students: Use colour-coded maps where key locations are pre-marked and focus on practising eastings first before adding northings.

Assessment

✔ Observation during partner tasks
✔ Oral responses in class discussions
✔ Review of plenary exit tickets
