Give each group of students a set of dice. You can use either standard six-sided dice with dots or polyhedral dice with numbers. You can make this activity harder or easier by giving them more or fewer dice.
In turn, each student shakes his/her dice. The student adds up the dice and announces the total. If the other students in the group agree that the total is correct, the student enters the score on his/her score sheet and the turn passes to the next student.
After five rounds, all students add up their scores and the highest total wins.
