The introductory paragraph exists to provide background information and context for your thesis. Basically, you are telling readers what they need to know in order to understand why the event that you are talking about is so important.
1. First sentence — it should NOT BE YOUR THESIS. Remember that the topic sentence of a paragraph (the first sentence of a paragraph) tells the reader what the paragraph will be about. This paragraph is about introducing your readers to your topic, so that’s more or less what your topic sentence should do. The introduction, based on the topic sentence, will be discussing the issue that your argument is about (tutoring, a special class, an assignment, etc.). MAKE SURE THAT YOUR FIRST SENTENCE IS DOING WHAT IT SHOULD.
2. Last sentence — this SHOULD BE YOUR THESIS. The reason behind this is that you will want to begin writing about your thesis as soon as you mention it, and you need to provide background BEFORE you state your thesis; your thesis should serve to transition from the introductory paragraph to the first body paragraph. Your thesis should:
include the event and the way it changed you
be only one sentence
3. The stuff between the first and last sentences — this will be the explanations and specific details that you need to include to explain the background for the event, whatever that happens to be. Your topic, remember, is NOT your thesis. You should use the first paragraph to explain your history with academics, school, formal education. The stuff that comes between the first and last sentences explains the TOPIC and prepares the reader for the THESIS.
Do not have an introductory paragraph that is under 100 words.
Notice that the first person is acceptable – no form of the word “you,” however, is correct.
