Write

Once you have your plan you can start developing your ideas into proper paragraphs. Don't worry about writing perfect prose at this stage. Just get the sentences down and then fix them during the revision stage. 

What makes a good paragraph?

Each paragraph should have one main idea. This main idea is usually summarised in the topic sentence which is often the first sentence (but not always).

All the sentences in a paragraph should:

• support the main idea (unity) 
• develop the main idea in a logical fashion (coherence)
