Have students get in groups of approximately five, and assign each group to a station. After the 3 minutes of activity, students stop and record their actual score, and calculate the difference between their prediction and actual score. Continue until each group has completed all stations. At the conclusion, discuss with students the accuracy of their predictions. Have students line up in relay lines at the other end.
Students run one at a time, take one beanbag, and return to the group.
The task is to predict how many beanbags the team, or individual, will return in 3 minutes. Putting a ball between their knees, students hop from one line to another. The task is to see how many round trips the team, or individual student, can make in 3 minutes. The task is for each student to volley the ball overhead as many times as he or she can in 3 minutes. If the ball drops or is caught, the count resumes at the last successful number.
