To write a 250-word essay, begin by selecting a topic and then create an outline that includes an appropriate amount of detail for the essay's length. An essay should include a brief introduction that summarizes the question being answered or topic being addressed, a longer middle section that includes supporting details or arguments related to the topic, and a conclusion that answers the question posed in the introduction.
Before beginning to write, have a good idea of what the essay is about. Try to summarize the point the essay makes or question it answers in a single sentence. All the information included in the essay should support the main idea. Don't digress or wander off topic while writing. Next, think of two or three supporting idea or arguments to make up the middle portion of the essay. Be able to tie these points back to the main idea. Finally, consider how to explain what the essay means or what conclusion it reaches.
A 250-word essay is about one typed, double-spaced page. Keep this length in mind when choosing a topic. Pick one that is complex enough to allow some room for argument or interpretation, but not one that is so broad or complicated it is impossible to summarize in limited space.
