Yes.... Never say "In this essay, I am going to tell you......"! If I were a teacher, that error would already take you down to a C! Sorry.
I would start with the basic five paragraph essay and elaborate into however many paragraphs you need.... I would do something like this
Paragraph #1: Introduction of thesis
Paragraph #2: Explain and define any words or phrases you may use in the paper
Paragraph #3: Issue 1
Paragraph #4: Issue 2
Paragraph #5: Conclusion of thesis
You cannot go wrong with a format like that. Of course, if your paper is two pages, you may not want five paragraphs; similarly, if you paper is 100 pages, you will want more than five paragraphs. Normally, if I have a paper that is more than ten pages, I will create subheadings to let my reader know the topics.
Good luck!
