1. Introduce:

  • Experimental and theoretical probability, with examples.
  • Probability distributions and frequency tables

2. Show common examples of how probability is related to everyday life, such as rolling dice, calculating batting averages, drawing cards from a deck, etc.

3. Discuss with students the following questions: What surprises you about these examples? Do you see patterns? Do you think they can be captured in mathematical terms?

4. Introduce key terms.
Compound event
Conditional probability
Dependent events
Experimental probability
Fundamental counting principle
n-factorial
Outcome
Theoretical probability

Tips and Tools

Use this Khan Academy video on marbles in a bag to introduce basic probability (3 minutes).

Probability also can be introduced using this video (5 minutes).

Students may benefit from working through simple examples of statistical or geometric probability.

Start Daily Learning Logs for individuals. If the logs will be graded, announce grading standards and expectations. Have students begin by listing 2 to 3 questions they have about probability.

Have students review the Glossary. They may also use an online tool for vocabulary building such as Visuwords. You can also have students download AccelaStudy to a smart phone or tablet to build on the key terms and vocabulary.
