Student lesson
- Tables organise data.
- Bar charts compare amounts.
- Line graphs show change over time.
- Charts need titles, labels and scales.
Words to know
rows and columns for data
a chart where bars show amounts
a graph that joins points to show change
a line with labels on a chart
1. Discover: The bean chart
Kojo records bean plant heights each day in a table. He then draws a line graph. “The line goes up steadily,” he says. His friend draws a bar chart of the same data. “I like bars to compare days,” she says.
Think: Which chart shows change over time?
2. Understand: Tables and charts
Idea 1: Tables
A table lists data in rows and columns with headings and units. It is the first step before a chart.
Idea 2: Bar charts
A bar chart uses bars to compare amounts, like numbers of sunny days per week. Bars should be the same width with equal gaps.
Idea 3: Line graphs
A line graph joins points to show how something changes over time. Draw an axis for time and an axis for the measurement, with labels and a title.
3. Worked examples
Example 1 (I show you): Which chart?
Heights over 7 days.
- Time series.
- Change.
- Line graph.
Answer: Use a line graph for change over time.
Example 2 (We do it together): Which chart?
Favourite fruits.
- Categories.
- Compare.
- Bar chart.
Answer: Use a bar chart to compare categories.
Example 3 (You try): Read
Line rises.
Show the steps and answer
- Heights increase.
- Plant grows.
- Pattern.
Answer: A rising line means growth.
Did you know?
Florence Nightingale used a famous circular chart to show how many soldiers died from preventable diseases and persuaded leaders to improve hospitals.
Why this matters
Charts make patterns easy to see and share.
4. Explore: Draw the charts
Draw a bar chart and a line graph from the same data.
- Write a table.
- Draw axes.
- Plot points.
- Join with a line and draw bars.
Think about it: what did you notice?
What did you notice? Each chart shows something different.

If a learner struggles
- Find the misconception: “All charts are the same.” They suit different data.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Choose and draw the right chart for data.
- 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 draws bar charts and line graphs. You do not need to be an expert to help.
- Chart something at home.
- Ask, “What does it show?”
- Label the axes.
- 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: draw a table; draw a bar chart; draw a simple line graph; read patterns.
Prerequisite knowledge. Grade 2 science ideas: observing carefully, making predictions, measuring with simple tools and running simple fair tests.
Materials. Graph paper, rulers, pencils and data tables. 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. Print graph paper. Provide data sets.
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). Show a messy table and a neat chart and ask, “Which is easier to read?”
Explanation (10 min). Teach charts.
Guided activity (10 min). Learners draw charts.
Independent activity (10 min). Learners read patterns.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which chart suits the data? What pattern?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “All charts are the same.” They suit different data.
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. Choose and draw the right chart for data. Enrichment. Look for one new example near your home or school, draw 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.
