Write your introduction so that the thesis appears at the end of the first paragraph. The opening sentence is used to get the attention of the reader, and this is followed by a widening of interest to show some context and then lead up to the point you want to make.
Make the first sentence of the next paragraph link to the ideas, or actual words, you used at the end of the introduction. Go on to write the strongest argument in favor of your thesis. Give evidence for your statements, preferably from firsthand experience or at least from primary sources.
Provide further support for your case in the next two paragraphs. Provide a supporting argument in each of them, finishing with what you think may be the weakest. Continue to use a linking device between the end of the preceding paragraph and the start of the new one. This gives a sense of continuity and flow so the reader is carried along more easily with what you are saying.
End the minipaper with a fifth paragraph that provides the conclusion. It should review the arguments from the earlier paragraphs to remind the reader of their strengths and then end with a confirmatory restatement of your thesis.
