A1.D.2.1 Select and apply counting procedures, such as the multiplication and addition principles and tree diagrams, to determine the size of a sample space (the number of possible outcomes) and to calculate probabilities.
In a Nutshell
Students will calculate probabilities to solve real world problems in the form of experimental probabilities, probability as a fraction of sample space or area, and used random number generators to conduct simulations.
Student Actions
|
Teacher Actions
|
|
- Use and connect mathematical representations by having the students use multiple representations to determine size of the sample space.
-
Implement tasks that promote reasoning and problem solving for students to calculate probabilities.
-
Encourage productive struggle as the students explore and discuss how to determine the sample size and whether to use a multiplication or addition principle.

Key Understandings
|
Misconceptions
|
|
- Students confuse when to use the addition or multiplication principle to calculate the possible outcomes.
