- Count the interval between dates.
- Timelines hide causes and feelings.
Words to know
a line that shows events in the order they happened
the order in which things happen
a period of one hundred years
the amount of time between two events
1. Discover: Sixty-nine years
Mr Cole draws a long line on the board. “One mark is ten years,” he says. He writes 1787, the year the first settlers arrived on the Freetown peninsula, 1792, the year Freetown was founded, 1827, the year Fourah Bay College opened, and 1961, the year of independence. “How many years from 1792 to 1827?” “Thirty-five,” says Mei. “And 1961 is long after,” says Abu. “Exactly,” says Mr Cole. “The spacing must be even to be honest.”
Think: What does this timeline not tell us about people’s lives?
2. Understand: Timelines
Idea 1: Order and scale
A timeline places events in a sequence. Spacing matters: if one centimetre means ten years, equal gaps on the line must show equal time. Label each event with its date and a short description. A century is one hundred years.
Idea 2: Time between events
The interval between two dates is found by subtracting the earlier from the later. From 1792 to 1827 is 35 years. From 1827 to 1961 is 134 years. Counting intervals helps us see whether change happened quickly or slowly.
Idea 3: What timelines hide
A timeline shows what happened and when, but not why, who was affected or how people felt. Two timelines of the same place may choose different events. Use timelines with documents, maps and other sources to build a fuller account.
3. Worked examples
Example 1 (I show you): Find
Years from 1792 to 1827.
- Subtract.
- Check.
- Say.
Answer: 35 years.
Example 2 (We do it together): Find
Years in a century.
- Think.
- Say.
- Check.
Answer: 100 years.
Example 3 (You try): Name
One thing a timeline hides.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Why events happened.
Did you know?
Some timelines show millions of years, while others show a single day in hours.
Why this matters
Timelines help us understand change and decide which events came first.
4. Explore: Build the timeline
Draw an evenly spaced timeline with 1787, 1792, 1827 and 1961. Add two events from your own school year. Calculate the interval between each pair and write what the timeline cannot tell us.
- Draw.
- Space.
- Calculate.
- Share.
Think about it: what did you notice?
What did you notice? Equal spacing keeps it honest.
5. Practise

If a learner struggles
- Find the misconception: “Events can go anywhere on a timeline.” Order and spacing matter.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a timeline strip.
- 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 builds an even timeline. Please talk about events in order. You do not need to be an expert to help.
- Make a week timeline.
- Count years.
- Discuss order.
- 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 timeline and sequence; build an even timeline; calculate time between events; say what a timeline hides.
Prerequisite knowledge. Grade 4 ideas: sources, maps and timelines from earlier units.
Materials. Paper, rulers, pencils. 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 timeline strips.
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 sixty-nine years story.
Explanation (10 min). Teach timelines.
Guided activity (10 min). Build the timeline.
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 timelines help us research the past?
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. “Events can go anywhere on a timeline.” Order and spacing matter.
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 timeline strip. 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.
