Paragraph Writing:
Remember that a paragraph is a way to organize ideas. Every time you change your topic you should start a new paragraph.
How many paragraphs do you need? Think of it like the left overs from a meal. Each container you put left overs in is = to a paragraph. So you can't tell how many containers you need until you look at your food (ideas) and decide what you are putting together. You might group potatoes and peas and dressing all together in one container. Would you put pie with your mash potatoes? Nope? Then grab a new container.
