Student lesson
- Latitude lines run east-west.
- Longitude lines run north-south.
- Coordinates name a place exactly.
- The Equator and Prime Meridian are 0 degrees.
Words to know
the distance north or south of the Equator, measured in degrees
the distance east or west of the Prime Meridian, measured in degrees
the numbers that give a place’s exact position on the grid
a unit used to measure angles and positions on Earth, shown as °
1. Discover: The treasure grid
Mr Cole draws a grid on a globe and tells a made-up treasure game: “Go to 8 degrees North, 12 degrees West.” “That is near Sierra Leone,” says Mei. “Latitude comes first,” says Mr Cole. “Lines of latitude are parallels, running east and west, measured from the Equator (0 degrees) to the poles (90 degrees). Lines of longitude, called meridians, run from pole to pole, measured from the Prime Meridian at Greenwich (0 degrees) to 180 degrees east and west.”
Think: Why is a shared grid helpful for ships and aircraft?
2. Understand: Latitude and longitude
Idea 1: The grid
The Earth’s grid has lines of latitude (parallels), which run east-west and measure distance north or south of the Equator in degrees, from 0 to 90. Lines of longitude (meridians) run pole to pole and measure distance east or west of the Prime Meridian, from 0 to 180.
Idea 2: Reading coordinates
Coordinates are written latitude first, then longitude, with directions: 8° N, 12° W. Find the line of latitude, then the line of longitude, and mark where they cross. Freetown is at about 8.5° N, 13° W, and Sierra Leone lies roughly between 7° and 10° N and 10° and 13° W.
Idea 3: Uses
The grid is used by ships, aircraft, satellites and phone maps to give exact locations. One degree of latitude is about 111 kilometres. The Prime Meridian passes through Greenwich in London, and the Equator passes through countries such as Ecuador, Gabon, Kenya and Indonesia.
3. Worked examples
Example 1 (I show you): Define
Latitude.
- Think.
- Say.
- Check.
Answer: Distance north or south of the Equator.
Example 2 (We do it together): Define
Coordinates.
- Think.
- Say.
- Check.
Answer: Numbers giving exact position.
Example 3 (You try): Write
Coordinates for Sierra Leone (about).
Show the steps and answer
- Think.
- Say.
- Check.
Answer: 8° N, 12° W.
Did you know?
Sailors once struggled to find longitude at sea until accurate clocks were invented in the 1700s.
Why this matters
Coordinates let us locate any place without confusion.
4. Explore: Coordinate game
Use a grid map to find five cities from coordinates. Then give coordinates (to the nearest degree) for three places and a classmate finds them. Mark Sierra Leone with its range.
- Read.
- Find.
- Give.
- Check.
Think about it: what did you notice?
What did you notice? Latitude first, longitude second.
5. Practise

If a learner struggles
- Find the misconception: “Longitude comes first.” Latitude comes first.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a coordinates chart.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child uses coordinates. Please find places on a map or globe together. You do not need to be an expert to help.
- Find coordinates.
- Play a grid game.
- Use a globe.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: define latitude, longitude, degree, coordinates; read and write coordinates; explain Equator and Prime Meridian; locate Sierra Leone.
Prerequisite knowledge. Grade 5 ideas: national geography, regions, climate, population and maps.
Materials. Grid maps, globe. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare grid maps.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Tell the treasure grid story.
Explanation (10 min). Teach the grid.
Guided activity (10 min). Coordinate game.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How do latitude and longitude locate any place?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Longitude comes first.” Latitude comes first.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Make a coordinates chart. Enrichment. Find one new example near your home or school, draw or write about it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
