Description:
The class will be divided in two groups.
Each group will have a list of questions that they will ask the other group.
The teacher and his/her assistant will monitor the activity and will count
the right answers each group obtains. At the end of the class, the teacher
will count all the points and there will be a winning team which will receive
a prize.
