Predicting Chance Outcomes Predicting Outcomes Where There are 2 Possibilities Slides 2-3 Predicting Outcomes Where There are 3 Possibilities Slide 4 Teachers The experiences can be repeated many times across the year. These interactives should be followed up wherever possible with ‘hands-on’ experiences. Where possible, coordinate the language provided (and student language) to the actions occurring onscreen. Hints To use the pointer pen option to write numbers as provided by students: Click Slide Show. Click From Beginning. Right click mouse. Click Pointer Options. Select Pen.

Say: Here is an arrow. When I click the mouse (or touch the screen) the arrow will fly off the screen to the top or bottom side. Ask: Can you know which side the arrow will fly off the screen when I click the mouse? Ask: What are your chances of guessing which side the arrow will go? (50/50) Say: Write down your guess for the first arrow. Click to fly the arrow. Ask: Did you guess correctly? Repeat for 9 more guesses. Ask: Did you guess some correctly and others incorrect? Why do you think that happened? Ask: How lucky would you have to be to guess correctly 10 out of 10 times?

Say: Here is an arrow. When I click the mouse (or touch the screen) the arrow will fly off the screen to the left or right side. Ask: Can you know which side the arrow will fly off the screen when I click the mouse? Ask: What are your chances of guessing which side the arrow will go? (50/50) Ask: If I fly the arrow off the screen 10 times, how many correct guesses do you think you will make? Why do you think that? Say: Write down your guess for the first arrow. Click to fly the arrow. Ask: Did you guess correctly? Repeat for 9 more guesses. Ask: Did you guess some correctly and others incorrect? Why do you think that happened? Ask: Did you think you would have about 5 correct guesses?

Say: Here is an ball. When I click the mouse (or touch the screen) the ball will move off the screen to the left or right side or to the bottom. Ask: Can you know which side the ball will move off the screen when I click the mouse? Ask: What are your chances of guessing which side the ball will go? Ask: Are your chances greater than or less than 50-50? Why do you think that? Ask: If I move the ball off 10 times, how many correct guesses do you think you will make? Why do you think that? Say: Write down your guess for the first move. Click to move the ball. Ask: Did you guess correctly? Repeat for 9 more guesses. Ask: Did you guess some correctly and others incorrect? Why do you think that happened? Ask: Is it harder to guess what might happen when the ball can move out 3 sides rather than 2 sides? Why do you think that? Ask: Would it be harder to guess what might happen if the ball could move out 4 sides rather than 2 or 3 sides? Why do you think that?
