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:
  • distinguish between the experimental and theoretical probability of single events
  • -> You have a die with numbers from 1‚ 6. What is the theoretical probability of rolling a 6, a 4, or a 1? Perform an experiment with a die, then compare the results.

  • using various polyhedrons as dice, identify the relationship between the number of faces and the probability of a single event

  • calculate theoretical probability using numbers between 0 and 1
  • -> Draw and label the net of a die to match each statement:
    • the probability of rolling an odd number is 5/6
    • the chance of rolling a prime number is 0/4
    • the likelihood of rolling a multiple of two is 5/8

  • demonstrate that different outcomes may occur when the same experiment is repeated
  • -> Toss a styrofoam cup onto a flat surface. Repeat several times, noting how often it lands in each position. Repeat for 40 tosses.
    • How many times did the cup land on its side? Top? Bottom?
    • How would you express each way as a probability? Side? Top? Bottom?

    Based on the results of this experiment, predict how many times the cup would land on its top if you tossed it 100 times.

  • compare experimental results with theoretical results
  • -> [No example for this prescribed learning outcome.]
