INTRODUCTION--Present your main idea and arguments (briefly). Grab attention. Use a quotation or ask a question.
BODY--Backs up your intro with proof, explanations, and details.
Write a topic sentence as a mini-intro or main idea, then explain with evidence and examples.
CONCLUSION: Ties everything together.
