Subject: Mathematics (9 - 12)
Title: The Spread of a Virus: Are All Viruses Virulent?
Description:

In this activity, students will watch a short video clip that displays how quickly past viruses have spread and how deadly they are. This will activate students' prior knowledge about rates of growth and provide the context for the simulation activity they will engage in during the next activity.

This activity results from the ALEX Resource Development Summit.

Title: The Spread of a Virus: Does Social Distancing Matter?
Description:

This exploration provides students the opportunity to actively engage in creating their own knowledge about exponential models. They are given the support to conduct their own simulation and record the information, make predictions using the data that they have collected, and compare their predictions to the technology generated models. Additionally, the technology element is necessary to make sense of the data in a more efficient manner as compared to hand calculations of procedures. The emphasis is to produce a deep conceptual understanding of rates of change of exponential functions in multiple representations and use that information to build up procedural fluency.

Subject: Mathematics (9 - 12)
Title: The Spread of a Virus: Which Virus Is More Virulent?
Description:

This activity allows teachers to formatively assess students' understanding of multiplicative rates of change from different representations. The activity presents four different viruses of different spread rates, and students are to determine which virus is the most virulent and justify their responses.

Title: Equivalent Expressions Using Exponents
URL: https://aptv.pbslearningmedia.org/resource/mgbh-math-ee-8exp/equivalent-expressions-using-exponents/
Description:

Students will apply their critical thinking skills to learn about multiplication and division of exponents. This interactive exercise focuses on positive and negative exponents and combining exponents in an effort to help students recognize patterns and determine a rule.
