The topic for this paragraph should be in the first or second sentence.
This topic should relate to the thesis statement in the introductory paragraph.
The introductory paragraph should also include the thesis statement, a kind of mini-outline for the paper: it tells the reader what the essay is about.
The last sentence of this paragraph must also contain a transitional "hook" which moves the reader to the first paragraph of the body of the paper.
Detractors feel, however, that writing to rule in this way is more likely to discourage imaginative writing and thinking than enable it.
A classic format for compositions is the five-paragraph essay.
The introduction is the first paragraph in your essay, and it should accomplish a few specific goals: capture the reader's interest, introduce the topic, and make a claim or express an opinion in a thesis statement.
It's a good idea to start your essay with a hook (fascinating statement) to pique the reader's interest, though this can also be accomplished by using descriptive words, an anecdote, an intriguing question, or an interesting fact.
Later, though, students may decide to stray from the standard five-paragraph format and venture into writing an exploratory essay instead.
Still, teaching students to organize essays into the five-paragraph format is an easy way to introduce them to writing literary criticism, which will be tested time and again throughout their primary, secondary, and further education.
