Objective - Part 1

Students will be able to describe events that are certain, impossible, likely, and unlikely to occur. Students will determine the likelihood of an event occurring using a probability scale.

Overview of the Lesson

Students are introduced to the idea of probability by discussing the likelihood of events occurring. Students focus on the "language" of probability as they use their life experiences to recall events that are certain, impossible, likely, and unlikely to happen. These events are recorded through the use of graphic organizers that relate to a current unit of study. Students are introduced to a probability scale, ranging from 0 - 1. They are encouraged to evaluate the chance of given events occurring and assigning the event a position on the probability scale. The activity immerses the students in experiences that promote discourse about probabilistic notions.
