Make two groups and ask a student for each group to play janken. The winner decides who wants to go first. (usually, students want to go after to see the first opened pictures.
Students choose two numbers. If they matched, the group gets the point. Then, make turns.
Write their points on the blackboard.
Click the number box to open and close. Or click the reset button to reset all open boxes.
