Trudy’s class has an English newspaper. The students write stories, articles and poems for it. Then they type and print their works out. The teacher posts everything on the wall so that it looks like a large, open newspaper.
One day Trudy said to the teacher, “Most newspapers have advertisements. Can we have some small ads in ours?” The teacher thought this was a very good idea. She made Trudy the advertising manager and Trudy asked the other students to offer things for sale in the newspaper. Here are some of the ads she received.
