Think about the most exciting Halloween costume you wore or have seen. Write a paragraph that describes it to your reader so that they imagine the same thing you see in your head. I included my example at the bottom of this post. Most importantly, make sure you description shows why this costume is so exciting!
Remember how to structure a paragraph. Your paragraph should have an introductory sentence that introduces what makes that costume exciting. Then, you should have many sentences of details. Finally, you should have a concluding sentence that summarizes the details in the previous sentences. Your paragraph should introduce your idea, provide details and summarize what you described.
As you write use detail words that describe the colors, materials, and parts of the costume. Use exciting vocabulary so your reader is excited too.
