## Calculator Controlled Robots - Mission 5: Game Spinner

#### Activity Overview

What are the chances that you can write your program on a TI-83+ that instructs your robot to spin and randomly land on numbers 1 to 8?
If the probability of that is low, can you write the program on the next page without looking at the detailed programming instructions? Try.

#### Before the Activity

Use a robot drawn 32 to 40 cm from mission 4. With a marker divide the circle into eight equal pieces and number 1 to 8 clockwise. Color odd numbered spaces red and the even numbered spaces black. Use your TI-83+ to write the program SPINNER (see PROGRAMMING INSTRUCTIONS if needed) Please see the attached PDF for more details for this activity. Or download the attached program.
