## Description

The Common Core State Standards for Grade 7 include the following probability standard:

*Investigate chance processes and develop, use, and evaluate probability models.*

Fathom is a powerful simulation tool that can help these concepts come alive for your students. This session will demonstrate how Fathom can be usedâ€”along with physical simulation tools such as dice, coins, and countersâ€”to help students understand probability. They will learn how probability can be used to predict what will happen, as well as how much error they can expect in those predictions. Both of these are important factors in probability models.

Although this is a Grade 7 standard in the Common Core, high school teachers will benefit from this webinar by learning what they should expect from students coming in, as well as how they can use Fathom to help students develop their understanding of the concepts covered in the probability standard.
