How to Develop Your Ideas in IELTS Writing Task 2 (With Examples)

You make a point, add a sentence or two, and then get stuck. Or you introduce a new idea because you can’t think of anything else to say. The solution isn’t to memorize more arguments. It’s to learn how to explain why your point matters and show what it means in practice.

Let’s look at how to do that.

1. Don’t stop at the first reasonable idea

Consider this question:

Some people believe that schools should teach children how to cook. To what extent do you agree or disagree?

Imagine you agree that cooking should be taught at school.

You might write:

Schools should teach children how to cook because cooking is an important life skill.

This is a relevant point, but it doesn’t give the reader much information. Why is cooking an important life skill? What difference does it make to a person’s life?

Instead of moving straight to your next idea, ask yourself: Why does this matter?

You could develop the point like this:

Schools should teach children how to cook because it helps them become more independent. For example, teenagers who can prepare a few basic meals won’t have to rely on their parents or buy takeaway food whenever they’re hungry. This skill can be particularly useful when they leave home for university or work.

Notice the progression:

• Main point: Cooking helps children become independent.

• Explanation: They can prepare meals without relying on others.

• Example: They can feed themselves when they leave home.

Each sentence adds something new. That’s what developing an idea means.

2. Use a chain of reasoning

Sometimes, an explanation is still too unclear. You state a benefit, but you don’t show how it leads to a meaningful result.

Look at this IELTS Writing Task 2 question:

Some people believe that public transport should be free. To what extent do you agree or disagree?

Here is an underdeveloped argument:

Free public transport would benefit the environment because fewer people would use cars.

The basic idea makes sense, but the connection needs explaining. Why would free public transport reduce car use, and how would that benefit the environment?

Try building a chain of reasoning:

Making public transport free could encourage more people to leave their cars at home. This would reduce the number of vehicles on the roads, particularly during rush hour, when traffic congestion is most severe. As a result, fewer cars would be burning fuel while stuck in traffic, potentially reducing transport-related emissions.

The logic moves from one point to the next:

Free public transport → more people use buses and trains → fewer cars on the road → potentially lower emissions.

You don’t need to write every possible step in every paragraph. The aim is to make the connection between your main point and your conclusion clear enough for the reader to follow.

3. Use examples to prove a point, not just repeat it

Examples can help develop an argument, but only if they add something useful.

Consider this question:

Some people think working from home is beneficial for employees. To what extent do you agree or disagree?

Here is a weak example:

Working from home is beneficial because it saves time. For example, it saves people time.

The example simply repeats the claim.

A more useful version would be:

Working from home can give employees more time for their personal lives because they no longer need to commute every day. For example, someone who previously spent two hours travelling to and from the office could use that time to exercise, prepare meals or spend time with their children.

The example makes the benefit concrete. It shows what saving time could mean in a person’s daily life. Before adding an example, ask yourself: Does this help the reader understand my point, or am I just repeating it in different words? You don’t need statistics, research findings, or complicated real-world cases. A believable, relevant example is often enough.

4. Don’t develop every idea in the same way

There isn’t one formula that works for every IELTS Writing Task 2 paragraph. The best way to develop a point depends on what you’re arguing.

For example, consider this question:

Some people believe that children should spend less time using digital devices. To what extent do you agree or disagree?

You could develop an argument about health:

Excessive screen time can reduce the amount of physical activity children get each day. If children spend most of their free time playing games or watching videos, they may be less likely to go outside, play sports or take part in other active hobbies. Over time, this could contribute to an unhealthy lifestyle.

Here, you explain a possible consequence.

Alternatively, you could argue that digital devices can support learning:

Digital devices can make learning more engaging by allowing children to interact with educational content. For example, a child who struggles to understand fractions from a textbook may find it easier to grasp the concept through an interactive exercise that provides immediate feedback.

Here, a specific example illustrates the benefit.

You can develop an idea by explaining a cause, describing a consequence, showing a practical example, or explaining how something works. Choose the approach that best supports your argument.

5. Practise developing ideas before writing a whole essay

If your body paragraphs are consistently underdeveloped, writing more complete essays may not be the most effective practice. Try this short exercise instead.

Question: Some people think university education should be free for everyone. To what extent do you agree or disagree?

Suppose your main argument is that free university education would give more students access to higher education.

Start with this point:

Free university education would give more students the opportunity to continue their studies.

Now develop it by answering these questions:

1. Why might some students be unable to attend university?

2. How would removing tuition fees change their situation?

3. What practical difference could this make to their future?

One possible development is:

Free university education would give more students the opportunity to continue their studies because tuition fees can be a significant financial barrier. Students from low-income families may decide against attending university because they cannot afford the cost, even if they have the academic ability to succeed. Removing tuition fees could allow more of these students to gain qualifications and apply for jobs that require a university degree.

Your task isn’t to memorize this paragraph. It’s to understand how the explanation grows out of the original idea. Now try developing a different point: Free university education could reduce financial pressure on students.

Can you explain why this matters and give a relevant example?

The key lesson

When you’re stuck in the middle of a body paragraph, don’t immediately search for another idea. Look at the point you’ve already made and ask what the reader needs to understand next. Sometimes you need to explain why something happens. Sometimes you need to show its consequences. Sometimes a practical example will make the argument clearer.

The important thing is that every sentence has a purpose and helps develop your response to the question. If you want to practice this before writing your next essay, try our free IELTS Writing Task 2 Planner. It helps you organize your ideas and plan your argument before you start writing.
