mBot: Not Your Average Robot (Gr. 5-7)

Using Variables and Averages for a Fun Game of Bocce Ball!


The mBot and the mBlock software are both perfect tools to explore mathematics and the concept of variables. By using variables to store information on the robot, students will attempt to hit an exact target on a bocce ball 'field' and use Mean, Median, and Mode to determine the score.
