Your teacher will give you a variety of news clippings that include percentages.

1. Take turns with your partner to sort the clippings into two piles: those that are about increases and those that are about decreases.

   1. For each clipping that you sort, explain to your partner how you decided which pile to sort it into.

   2. For each clipping that your partner sorts, listen carefully to their explanation. If you disagree, discuss your thinking and work to reach an agreement.

2. Were there any clippings that you had trouble deciding which pile they should go in?

In the previous activity, you sorted news clippings into two piles.

1. For each pile, choose one example. Draw a diagram that shows how percentages are being used to describe the situation.

   1. Increase Example:

   2. Decrease Example:

2. For each example, write two questions that you can answer with the given information. Next, find the answers. Explain or show your reasoning.

1. Choose the example that you find the most interesting. Create a visual display that includes:

   • A title that describes the situation.
   • The news clipping.
   • Your diagram of the situation.
   • The two questions you asked about the situation.
   • The answers to each of your questions.
   • An explanation of how you calculated each answer.

   Pause here so your teacher can review your work.

2. Examine each display. Write one comment and one question for the group.
3. Next, read the comments and questions your classmates wrote for your group. Use the feedback from your classmates to revise your display.
