You can play this like a board game using dice to move from start to finish, with small groups of players.
 
But I will explain a different way to play.
 
Rule: students should answer questions about things they did during summer vacation. 
 
How to play:
 
1. Students have 1 paper each. Make a pair and play janken. Winner asks the first question 'Did you eat watermelon?' The partner says either 'Yes, I did' or 'No, I didn't.' Then the partner signs the question space.
2. The loser doesn't ask a question. Only the winner moves to the next question space.
3. Both students find new classmates, play janken and play again.
4. To finish the activity a student needs to win janken 8 times.
