An opinion is similar to an argument but it has reasons. Today you will write an opinion about something. Imagine that you really love pizza and want it for dinner. But your brother or sister really wants tacos. You get into an argument. It gets louder and louder. "I want pizza," "I want tacos," "PIZZA!" "TACOS!" "PIZZA!" "TACOS!" and so on. The better way to convince people is to give reasons that support your opinion. So you might say, "I think we should go for pizza. I think this because, one, we can get it delivered quickly and have fun talking, and two it is cold out, and pizza will warm us up." When you want to convince your readers, it is important to not only state your opinion but give lots of reasons and examples. Here's a tip: when you want to say more about a reason for your opinion, it helps to say, I think that because. . . or for example. . . Finally, add details.
