Words to know
The biggest number.
The smallest number.
All added together.
How many more or fewer.
1. Discover: what does the graph say?
Look at the fruit graph: mango 6, orange 4, banana 8, pawpaw 2. What can you say about the class?
2. Understand: reading graphs
First read the title and labels. Then answer questions.
- Most: banana (8). Least: pawpaw (2).
- Total: 6 + 4 + 8 + 2 = 20 children.
- Mango and orange together: 6 + 4 = 10.
- How many fewer chose pawpaw than orange: 4 − 2 = 2.
3. Explore: question time
You need the fruit graph.
- Find the most popular fruit.
- Find the total.
- Find mango and orange together.
- Ask your own question for a partner.
Think about it: what did you notice?
Banana is most; total 20; mango + orange = 10.
4. Practise
Guided practice
Question 1. Most popular?
Banana (8).
Question 2. Total children?
6 + 4 + 8 + 2 = 20.
Question 3. Mango + orange?
10.
Independent practice
- Least popular fruit
- Total number of children
- How many fewer chose pawpaw than orange?
- Difference between most and least
- Mango + banana
Answers are in the answer key below. Try first, then check.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Find the most and least | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Find the total of all bars | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Find how many more or fewer | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O4 Explain what the graph shows | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
Proposed Courseversity thresholds for this page: Bronze = at least 3 of 5 core questions correct; Silver = all 5; Gold = all 5 plus the challenge. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: Adding only two bars when asked for the total. Total means all the bars.
- Explain another way: use real objects first, then pictures.
- Show a simpler example: Use counters for each bar to answer the questions.
- 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.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: find the most and least; find the total of all bars; find how many more or fewer; explain what the graph shows.
Prerequisite knowledge. Lesson 4.
Materials. Counters (stones, seeds or bottle tops), paper, pencils, board or chalkboard. Low-resource options: use stones, seeds, sticks, bottle tops or drawings in the sand or on the board instead of printed materials.
Preparation. Gather the counters and draw the example pictures on the board before the lesson.
Suggested duration. 35–45 minutes.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Start with the Discover situation and let learners suggest ideas before you teach.
Explanation (10 min). Teach the Understand section with real objects first, then pictures, then symbols and words.
Guided activity (10 min). You need the fruit graph. Learners follow the Explore steps in pairs.
Independent activity (10 min). Learners complete the independent practice and the worksheet.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Teacher explanation notes. Use the concrete, pictorial, abstract order: real objects first, then pictures, then symbols and words. Return to real objects whenever a learner needs support.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and work with a partner; say each step aloud together. Extension. Ask learners to make up their own example and explain it to a partner.
Formative assessment. Listen to learner explanations, ask “how do you know?”, and check the independent work.
Misconceptions. Adding only two bars when asked for the total. Total means all the bars.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz and worksheet on this page. The 10-mark scheme and all answers are in the answer key above. Re-check every answer and the marking scheme before publication.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Use counters for each bar to answer the questions. Enrichment. Invite learners to find or create three more examples at home or in the classroom and explain them. Homework. See above.
Teacher reflection. After teaching, record: which concepts learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
