Student lesson
- Bar charts compare amounts like rainfall.
- Line graphs show change like temperature.
- Axes need labels and scales.
- Patterns help us predict.
Words to know
a drawing that shows data
a labelled line on a graph
equal steps on an axis
a regular repeated trend
1. Discover: The rainfall bars
Kwesi draws a bar for each month of rainfall. The bars are small in January and February, grow tall in May and June, then fall again. “The rains come in the middle of the year,” he says. “The graph shows it clearly.”
Think: What pattern does the graph show?
2. Understand: Weather graphs
Idea 1: Choosing
Use a bar chart to compare amounts such as monthly rainfall. Use a line graph to show change over time such as temperature through the day.
Idea 2: Drawing
Draw two axes. Choose an equal scale. Label each axis with a name and unit. Give the graph a title.
Idea 3: Reading
Look for a pattern: highest, lowest, rises and falls. Use it to explain what the weather does through the year.
3. Worked examples
Example 1 (I show you): Choose
Monthly rain.
- Compare.
- Bar chart.
- Months.
Answer: Use a bar chart.
Example 2 (We do it together): Choose
Day temperature.
- Change.
- Line graph.
- Time.
Answer: Use a line graph.
Example 3 (You try): Read
Tall bars May.
Show the steps and answer
- Wet season.
- Pattern.
- Rainy months.
Answer: The graph shows the wet season.
Did you know?
Meteorologists use graphs of past weather to help forecast future weather.
Why this matters
Graphs make weather patterns easy to see and share.
4. Explore: Graph the week
Draw a bar chart and a line graph from weather data.
- Use a week’s table.
- Draw rainfall bars.
- Plot temperature points and join.
- Describe the patterns.
Think about it: what did you notice?
What did you notice? Each graph told a different story.

If a learner struggles
- Find the misconception: “All graphs are the same.” Different jobs.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Draw and read weather graphs.
- 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 weather graphs. You do not need to be an expert to help.
- Graph the week’s weather.
- Ask, “What pattern?”
- 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: choose the right graph; draw a bar chart of rainfall; draw a line graph of temperature; read patterns.
Prerequisite knowledge. Grade 2 weather ideas: describing weather, the seasons, and how weather affects daily life.
Materials. Graph 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. Print graph paper.
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 table and a graph and ask, “Which is clearer?”
Explanation (10 min). Teach graphs.
Guided activity (10 min). Learners draw.
Independent activity (10 min). Learners read.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What pattern does the graph show?
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 graphs are the same.” Different jobs.
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. Draw and read weather graphs. 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.
