Math K-7 IRP Statistics and Probability (Chance and Uncertainty)

Students use experimental or theoretical probability to represent and solve problems involving uncertainty.


Prescribed Learning Outcomes Illustrated Examples
It is expected that students will:
  • identify an outcome using the terms possible, impossible, certain, or uncertain
    		• -> For each of the following, draw a spinner that matches the statement:
    • It is impossible to land on 5.
    • You are more likely to land on red than on green.
    • It is equally likely that the spinner will stop on red, yellow, blue, or white.
    • You are certain to spin an even number.
  • compare outcomes using the terms equally, likely, more likely, or less likely
    		• -> Pull out a cube, record the colour, and replace the cube in the bag. Repeat a number of times. What is likely to come out next?
    • If we change the cubes to 5 red and 1 green, will the outcome be different?
    • What if we increased the number of cubes?
    • How have the outcomes changed?
    • What other things might affect the outcomes?
  • design and conduct experiments to answer their own questions
    		• -> Chinus and Scott put tiles in a bag -- 4 yellow and 1 green. Chinus makes up a game. He says he gets 1 point for every yellow tile and Scott gets twice as many points for every green tile they pull from the bag. Do you think the game is fair?

    Play the game a number of times, stopping each game when one colour has earned 10 points. Was the game fair? If not, how would you change it to make it fair?

    Scott says the game would be better if there were 10 green and 40 yellow tiles in the bag. Would this change the game? Explain your answer.
