Words to know
A graph that uses pictures.
Says what one picture means.
Pictures in a line.
The name of the graph.
1. Discover: children and games
A graph uses one picture for 2 children. A row has 5 pictures. How many children is that?
2. Understand: picture graphs with a key
A picture graph shows data with pictures. The key tells us how many each picture stands for. If the key says 1 picture = 2 children, then 5 pictures are 5 × 2 = 10 children, and 3 pictures are 6.
If 1 picture = 5, then 4 pictures = 20. A half picture is half the key: if 1 picture = 10, then a half picture is 5, so 3 and a half pictures are 35.
Always read the title and key first.
3. Explore: make a picture graph
You need paper and crayons.
- Use tally results from Lesson 2.
- Choose a key: 1 picture = 2.
- Draw pictures for each row.
- Say which row is longest.
Think about it: what did you notice?
Rows show the data in pictures.
4. Practise
Guided practice
Question 1. 1 picture = 2. Row has 5 pictures.
10.
Question 2. 1 picture = 2. Row has 3 pictures.
6.
Question 3. 1 picture = 5. Row has 4.
20.
Independent practice
- Key 1 = 2, 4 pictures
- Key 1 = 5, 3 pictures
- Key 1 = 10, 5 pictures
- Which row is longest?
- What does a key tell us?
Answers are in the answer key below. Try first, then check.
5. Apply: everyday mathematics
A graph key says 1 picture = 5 children. A row has 6 pictures. How many children?
Show a sample answer
30 children.
6. Common mistake
Fix: Use the key to find the value.
7. Check and master
Answer all questions. You will see feedback after each one.
Your result appears here after you answer every question.
8. Key takeaways
- Read the key first.
- Skip count by the key.
- Half picture is half the key.
9. Next lesson
Next lesson: Bar graphs. Keep going with the next idea in this course.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Read a key where one picture stands for 2 or 5 | 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 Read the number from a row of pictures | 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 Draw a picture graph from tally | 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 Compare rows | 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: Counting each picture as 1. Use the key to find the value.
- Explain another way: use real objects first, then pictures.
- Show a simpler example: Use key 1 picture = 1 first, then 2.
- 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: read a key where one picture stands for 2 or 5; read the number from a row of pictures; draw a picture graph from tally; compare rows.
Prerequisite knowledge. Lesson 2; skip counting.
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 paper and crayons. 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. Counting each picture as 1. Use the key to find the value.
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 key 1 picture = 1 first, then 2. 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.
