IntroductionApperceptionTeacher explain a story about the way to choose a place before the game startor other by using the lotteryMotivationTeacher explain the learning objectiveb. Main Activity
2. Make teams that consist of 5-7 studentsEach team is asked to demonstrate the experiment of tossing of coin fivetimes.Each team is asked to explain their workBy using ask-question teacher ask student to know the sample point andsample space of the experiment of tossing the coin.Student is asked to do the experiment again by using 5 different color marblesStudent do the exercise.c. ClosureStudent is asked to summarize about the sample point and sample spaceH. Learning SourceTextbook, environment, die, coin, bridge card, numbered card
