Objective   6 Identify an outcome as possible, impossible, certain, uncertain.

Problem   Randy made up a special die. The picture shows three sides of her die. Randy wrote these sentences about her die: It is impossible to roll an even number. It is possible to roll a 5, but not a 1. It is certain that you will never roll a number greater than 5. You are more likely to roll a 3 than a 5. Draw a net to show all sides of her die.

Manipulative   Materials: blank six-sided dice (or blank spinner mats, or probability tops). Using a blank die, construct a new die for each statement below: it is certain that you will roll a 5. it is uncertain whether you will roll a 2 or a 4. it is possible to roll any even number less than 11. it is impossible to roll a number greater than 3, but certain that you will roll a 4. it is uncertain whether you will roll a 2, 4 or 6, but it is more likely to roll a 6 than a 4, and more likely to roll a 4 than a 2. it is uncertain just what number you will roll. Take each of these dice, one at a time, and construct a simple experiment to check your answer. Write two other sentences like the ones above and give them to a friend to construct the appropriate die.

Game   Materials: overhead spinner, spinner mat with probability vocabulary. This game is played against an opponent. Player 1 twirls the spinner on the mat in the top left corner, thus identifying a task for Player 2. The second player now takes the spinner mat and places it on any of the remaining 3 mats and twirls it. If the spinner lands on a space to successfully complete the task, player 2 scores a single point. Roles are now reversed. First player to accumulate 5 points is the winner. Adaptations: Add other tasks to the first spinner mat. Replace the spinners with other types of materials (e.g., cards, beans, etc.)
