Understand the probability of an event happening is a number between 0 and 1, ranging from impossible to certain.

This is students' first introduction to probability, however, they will probably have an informal vocabulary and understanding of what is “fair” or likely or unlikely. Make the connection between these understandings and the values, both decimal and fractional, between 0 and 1 that probabilities can take on. It may also be helpful to have an open discussion about what students know or think they know about probability before the lesson. This may help bring any misconceptions to the surface that can be addressed throughout the unit.
