Working with Signed Numberes (Integers): []
Solving Equations Game: [] __ Extra Credit: __ Probability in Advertising Look at newspapers and magazines for examples of how numbers are used in advertisements. Attach at least three examples and highlight where numbers are used. For example, it is not unusual to see something like “two-thirds less fat than the other leading brand” or “four out of five dentists recommend Brand T gum for their patients who chew gum.” Why do advertisers use numbers like these? What information are they trying to convey? Do students think that the numbers give accurate information about a product? Why or why not? **They Said What?** Look at newspapers or magazines for examples of how politicians, educators, environmentalists, or others use data such as statistics and probability. Attach at least one example. Analyze the use of the information. Why did the person use data? What points were effectively made? Was the data useful? Did the data strengthen the argument? Write a statement or two that provides evidence to support your idea.

WINNING ISN'T EVERYTHING
Choose your favorite sports games and find the scores of several games. Write down these scores to use for this activity. Mark ten sets of game scores you wish to use in the activities. <span style="color: rgb(0,0,0);">Complete the following activities.

Write your results on a separate piece of paper. Be creative! <span style="color: rgb(0,0,175);">
 * <span style="color: rgb(175,0,0);">Use the loser's score as the numerator and the winner's score as the denominator. Reduce these fractions to lowest terms.
 * <span style="color: rgb(175,0,0);">Using the same scores from the ten games, make the numerator the winner's score and the denominator the loser's score. Change the improper fraction to a mixed number expressed in lowest terms.
 * <span style="color: rgb(175,0,0);">Add the fractions you made from each of the first five games that were chosen to the mixed number you created from each of the same first five games. In other words, you will have 5 separate addition problems. (One problem for each game.)
 * <span style="color: rgb(175,0,0);">Using the mixed number you made from each of the last five games, subtract the fraction you created from each of the last games. In other words, you will have 5 separate subtraction problems. (One problem for each game.)
