Introductory Sentence: This is the first sentence of the body paragraph. It should inform your readers of what you will be talking about in that passage. Make sure to keep it brief. An example of an introductory sentence is, "For holidays, my family sets up the decorations, cooks a meal, and invites all of the relatives over."
Supporting Sentences: These should support your introductory sentence. If you're talking about a holiday celebration, you may want to describe any traditions you have. (There are usually around 5 supporting sentences in each body paragraph.)
Concluding Sentence: This sentence should sum of the main idea of the paragraph and hint at what will be coming in the next passage so you can make a smooth transition.
