Running Time: Self-paced* 

Students are motivated to learn as they drive their virtual race car around the track. Each lap presents a new prompt based on unit content. As they drive around the track, racers are presented with sets of answer options. In order to tag the correct answer, they move the car to the right or left (by turning their heads) to run over their selection. The more correct answers they drive over, the higher score they will earn. Racers select their driving speed for a comfortable pace.
