Today I visited a special city at a Web site! I saw homes, stores, cars, and a school. I also learned about different ways to recycle. Then I solved problems by writing number sentences. I figured out that Grace saw            apple peels in the compost bin.

You can find out more about this topic by asking your teacher or parents to show you other Web sites.
