Lesson 2
Playing with Probability
Lesson Narrative
The mathematical purpose of this lesson is to make connections to prior knowledge about probability and to use probability to interpret data. The work of this lesson connects to previous work because students learned about chance events and probability in previous grades. The work of this lesson connects to upcoming work because students will describe and use the sample space for chance experiments to calculate the probability of compound events. In the take turns activity, students trade roles explaining their thinking and listening, providing opportunities to explain their reasoning and critique the reasoning of others (MP3).
Learning Goals
Teacher Facing
 Describe (in writing) the sample space for chance experiments. Use the sample space to calculate the probability of compound events.
 Generate (in writing) and critique (orally) probability models that meet specific criterion.
