Lesson 2: IELTS Writing Task 1 | IELTS Preparation

Warm-up

What Is Writing Task 1?

In IELTS Academic Writing Task 1, you describe visual information — a graph, chart, table, diagram, or map — in at least 150 words. You have about 20 minutes for this task.

The key skill is identifying and describing trends, not listing every single number. The examiner wants to see that you can select the most significant information and present it clearly.

Many candidates lose marks here by writing a list of data points instead of analysing what the data shows. Your job is to be a reporter, not a photocopier.

Key Concepts

Graph Types You'll See

Click each card to see what each graph type tests you on.

Line Graph

Shows changes over time

Describe trends: rising, falling, fluctuating. Focus on overall direction, not every data point.

Bar Chart

Compares categories or groups

Compare and contrast: highest vs. lowest, similarities and differences between groups.

Tap to flip

Pie Chart

Shows proportions of a whole

Describe proportions: "the largest share," "accounted for," "made up approximately."

Tap to flip

Table

Displays specific numerical data

Select key figures. Don't describe every cell — find patterns, comparisons, and extremes.

Tap to flip

Process Diagram

Shows stages in a sequence

Use passive voice and sequencing language: "First, the raw materials are collected. Next, they are processed."

Tap to flip

Map

Shows changes to a place over time

Describe changes: "was replaced by," "was converted into," "a new building was constructed."

Sample Analysis

Bad vs. Good Data Description

Compare these two descriptions of the same line graph showing internet usage in three countries from 2000 to 2020.

📈

Describing a Line Graph

Internet usage in the USA, Brazil, and India (2000–2020)

✗

In 2000, the USA had 43%. In 2005, it had 68%. In 2010, it had 74%. Brazil had 5% in 2000. In 2005, Brazil had 21%. In 2010, Brazil had 41%. India had 0.5% in 2000...

⚠ This just lists numbers. No overview, no trends, no analysis. The examiner sees no ability to summarise.

✓

Overall, internet usage increased in all three countries, with the USA consistently leading. The most significant growth occurred in India, which rose from under 1% to over 40%. While the USA saw steady growth, Brazil and India experienced more dramatic increases, particularly after 2010.

✅ Identifies the overall trend, compares countries, highlights the most significant change, and uses precise trend language.

Pattern Spotlight

Task 1 Structure

Every Task 1 response should follow this four-paragraph structure. The overview is the most important paragraph — never skip it.

💡 The 4-Paragraph Task 1 Template

Paragraph	Purpose	Target Length
Introduction	Paraphrase the question. Never copy it word-for-word.	1–2 sentences
Overview	State 2–3 key trends or features. No specific numbers here.	2–3 sentences
Body 1	Describe the first group of data with specific figures.	3–4 sentences
Body 2	Describe the second group with comparisons.	3–4 sentences

Target

150+ words total. Spend ~3 minutes planning, ~15 minutes writing, ~2 minutes checking.

💡

Pro Tip

ALWAYS write an overview paragraph. It's worth more than any amount of detail. Examiners look for your ability to identify main trends, not to list every data point. Without an overview, your maximum score for Task Achievement is Band 5 — no matter how accurate your details are. Write the overview right after your introduction, before the body paragraphs.

Practice

Test What You've Learned

Complete these exercises to practise your Task 1 skills.

Multiple Choice Exercise 1 of 4

Which is the best overview statement for a graph showing rising car sales in Asia and falling sales in Europe?

In 2010, Asia sold 5 million cars and Europe sold 7 million cars.

Overall, car sales in Asia increased significantly while European sales experienced a notable decline over the period.

The graph shows car sales. There are two lines. One goes up and one goes down.

I think car sales in Asia will continue to rise because of economic growth.

🎉

Correct! Option B identifies the key trends without specific numbers. A uses specific data (wrong for overview), C is too informal, and D gives opinions (never do this in Task 1).

💡

Not quite. The best overview is B. An overview should identify key trends without specific numbers and never give opinions.

Fill in the Blank Exercise 2 of 4

Complete the trend description: "The unemployment rate rose steadily from 2005 before it ___ 12% in 2012."

The unemployment rate rose steadily from 2005 before it 12% in 2012.

🎉

Excellent! "Peaked at" describes hitting the highest point. You could also say "reached a peak of" or "hit a high of."

💡

Almost! The best answer is "peaked at" or "reached a peak of." This phrase describes the highest value in a trend.

Multiple Choice Exercise 3 of 4

What is the correct paragraph order for a Task 1 response?

Body 1 → Body 2 → Overview → Introduction

Introduction → Body 1 → Body 2 → Conclusion

Introduction → Overview → Body 1 → Body 2

Overview → Introduction → Body 1 → Body 2

🎉

Perfect! Introduction → Overview → Body 1 → Body 2. Note: Task 1 does NOT need a conclusion. The overview serves that purpose.

💡

Not quite. The correct order is Introduction → Overview → Body 1 → Body 2. No conclusion is needed in Task 1.

Word Order Exercise 4 of 4

Arrange these words into a correct trend description:

sharply

increased

2010

the

rate

🎉

You got it! "The rate increased sharply in 2010." Subject + verb + adverb + time reference. This is a natural Task 1 sentence.

💡

Close! The correct order is: "the rate increased sharply in 2010."

Key Takeaways

Task 1 = 150+ words in about 20 minutes. Describe visual data — don't give opinions.

6 graph types: line graph, bar chart, pie chart, table, process diagram, map.

The overview is essential. No overview = maximum Band 5 for Task Achievement.

4-paragraph structure: Introduction → Overview → Body 1 → Body 2.

Use precise trend language — "increased sharply," "remained stable," "peaked at."

Identify trends, don't list numbers. Be a reporter, not a photocopier.
