Student lesson

The lesson in 60 seconds

  1. Read the question twice.
  2. Find the answer on the graph.
  3. Use add and subtract for total and more questions.
  4. Make a statement from the graph.

Words to know

question
Something we ask.
statement
A sentence that tells a fact.
half
One of two equal parts.
altogether
The total.

1. Discover: graph questions

Look again at the fruit graph. What questions can you ask? Can you also say a fact about the class?

2. Understand: answering questions

From the graph (mango 6, orange 4, banana 8, pawpaw 2) we can answer many kinds of question.

  • How many? 8 chose banana.
  • Which? Banana is the favourite.
  • How many more? Banana has 4 more than orange (8 − 4).
  • Altogether: 20 children.
  • Half: orange (4) is half of banana (8).

A statement tells a fact: “Banana is the favourite fruit in our class.”

Favourite fruit: use the bars to answer questions

Idea 1: How many?

The fruit graph shows mango 6, banana 8, orange 4 and pawpaw 2. How many chose banana? 8.

Idea 2: More, total, half

How many more chose banana than orange? 8 − 4 = 4. How many altogether? 6 + 8 + 4 + 2 = 20. Half of 8 is 4, so orange is half of banana.

Idea 3: Make a statement

A statement is a sentence that tells a fact: “Banana was chosen by 8 children.”

Why read twice? It stops us answering a different question.

Remember: Read the question. Use the graph. Write the answer in a sentence.

3. Worked examples

Example 1 (I show you): How many

How many chose banana?

  1. Read the banana bar.

Answer: 8

Example 2 (We do it together): More

How many more bananas than oranges?

  1. 8 − 4.

Answer: 4

Example 3 (You try): Half

Which fruit is half of banana?

Show the steps and answer
  1. Half of 8 is 4.

Answer: Orange

Did you know?

Scientists, shops and schools answer questions from graphs every day.

Why this matters

Answering questions from a graph shows we understand the data.

4. Explore: quiz the graph

You need the fruit graph.

  1. Write a how many question.
  2. Write a how many more question.
  3. Write a total question.
  4. Swap with a partner and answer.
Think about it: what did you notice?

Check answers against the graph.

5. Practise

Say it in a sentence

Use these starters when you talk about the lesson. Say them out loud.

  • ___ children chose ___.
  • ___ more chose ___ than ___.
  • Altogether there are ___.
  • My statement is ___.

Guided practice

Question 1. How many more bananas than oranges?

8 − 4 = 4.

Question 2. Which fruit is half of banana?

Orange (4).

Question 3. If 5 more choose pawpaw, how many choose pawpaw?

2 + 5 = 7.

Independent practice

Level 1: Start

  1. How many chose banana?
  2. How many more bananas than oranges?
  3. How many altogether?
  4. Mango + pawpaw?
  5. Write one statement about the graph.

Level 2: Grow

  1. How many chose mango?
  2. How many fewer chose pawpaw than banana?

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

  1. Find the misconception: Answering a different question from the one asked. Read the question twice.
  2. Explain another way: use real objects first, then pictures.
  3. Show a simpler example: Answer one question at a time using counters for the bars.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child answers questions from a graph and writes statements. You do not need to be good at mathematics to help.

  • Make up questions about a graph and take turns answering.
  • Ask: which is the most? the least?
  • Write a statement from the graph.
  • 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: answer how many and which questions; answer more and fewer questions; answer total and half questions; make a statement from a graph.

Prerequisite knowledge. Lessons 1 to 6.

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. 45–60 minutes. It can be split into two shorter sessions.

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.

Key questions. What does the question ask? Where is the answer on the graph? Does it make sense?

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. Answering a different question from the one asked. Read the question twice.

13–15. Assessment questions, answer keys, marking scheme

Use the quiz and worksheet on this page. The 8-mark exam practice scheme, the 10-mark scheme and all answers are in the answer sections above. Re-check every answer and the marking scheme before publication.

16–19. Remediation, enrichment, homework, teacher reflection

Remediation. Answer one question at a time using counters for the bars. 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.
