- Graphs show data as pictures.
- Organised data shows patterns.
Words to know
to put things into groups by a rule
a set of things alike in some way
a picture of data
something that repeats
1. Discover: The button box
Gift pours a box of buttons on the table. She sorts them by colour into red, blue and green. Then she counts and draws a block graph. “There are more red buttons than blue,” she says. “Organising shows me this quickly.”
Think: How did sorting help Gift?
2. Understand: Organising data
Idea 1: Sorting
To sort, choose a rule such as colour or size and put each thing in a group. Each object belongs in one group.
Idea 2: Two rules
A Venn diagram uses two circles that overlap. A Carroll diagram uses a table with yes and no. They show things that have both properties, one property or neither.
Idea 3: Graphs and patterns
A block graph stacks a block for each object. We read the tallest column to find the most. We look for a pattern, such as most plants growing near a window.
3. Worked examples
Example 1 (I show you): Sort by colour
Red, blue, green buttons.
- Make three groups.
- Count each.
- Compare.
Answer: Three groups: red, blue and green.
Example 2 (We do it together): Venn
Hard and shiny things.
- Hard only.
- Shiny only.
- Both: metal spoon.
Answer: A metal spoon is both hard and shiny.
Example 3 (You try): Read a graph
Red is tallest.
Show the steps and answer
- Count blocks.
- Compare.
- Red has the most.
Answer: Red buttons are the most common.
Did you know?
Scientists sort millions of living things into groups called species to understand nature.
Why this matters
Organised data is easier to read and explain.
4. Explore: Sort and graph
Sort objects by a rule and make a block graph.
- Collect 20 safe objects.
- Choose a rule.
- Count each group.
- Draw a block graph.
Think about it: what did you notice?
What did you notice? Sorting makes counting easy.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Sort objects into groups using a rule | 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 Use a Venn or Carroll diagram | 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 Make a block graph | 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 |

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Each object can be in many groups at once.” One rule at a time.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Sort objects by colour and make a graph.
- 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 learns to organise observations in groups, diagrams and graphs. You do not need to be an expert to help.
- Sort laundry or toys together.
- Ask, “What is the rule?”
- Draw a graph of favourite fruits.
- 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: sort objects into groups using a rule; use a Venn or Carroll diagram; make a block graph; describe a pattern in sorted data.
Prerequisite knowledge. Grade 1 science ideas: looking carefully, using the senses safely and talking about what we notice.
Materials. Buttons, beans or leaves, paper, crayons and a ruler. 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. Gather small objects. Prepare a block graph template. Draw circles on 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). Pour out a box of buttons and ask, “How can we sort these?”
Explanation (10 min). Teach sorting, Venn and graphs.
Guided activity (10 min). Learners sort and graph.
Independent activity (10 min). Learners describe patterns.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What is the rule? What 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. “Each object can be in many groups at once.” One rule at a time.
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. Sort objects by colour and make a graph. 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.
