This is in interactive PowerPoint Presentation game inspired by the game show on TV "Deal or No Deal". The concept is very the same with the mentioned TV game show. There are brief cases to choose from. Each briefcase contains a question and the name of the player. Tally of points are as follows:
1st briefcase opened = 1 point
2nd briefcase opened = 2 points
3rd briefcase opened = 3 points
and so on and so forth....
25th briefcase opened = 25 points
The game becomes even exciting in the last or remaining brief cases still to open because the points also becomes higher. And to add more intense to this game, inform the students that each briefcase opened with the wrong answer by the player is a deduction of points. This will give eagerness to the students to really do their best shot and deliver the correct answer.
On how you deliver this game, as a teacher-host, study how the host on the TV deal with the entire run of the program.
P.S when you become more familiar with the concept of this PPP, surely you will love repeating this activity to the class and you will even love making another PPPs with the same concept. Enjoy and have fun using this Deal or No Deal interactive PPP on Subject-Verb Agreement. :)
