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.

This activity results from the ALEX Resource Development Summit.

Title: Interactive Tools | Against All Odds: Inside Statistics
URL: https://aptv.pbslearningmedia.org/resource/bb2042d8-5e7f-4ccc-bdab-9690bfef6653/interactive-tools-against-all-odds-inside-statistics/
Description:

These interactive tools give students an opportunity to explore more about stemplots, control charts, and histograms as covered in the Against All Odds statistics series. Simulations allow students to explore statistics methods in-depth using their own data.

Title: Algebra I Module 2, Topic D: Numerical Data on Two Variables
URL: https://www.engageny.org/resource/algebra-i-module-2-topic-d-overview
Description:

In Module 2, Topic D, students analyze relationships between two quantitative variables using scatterplots and by summarizing linear relationships using the least-squares regression line. Models are proposed based on an understanding of the equations representing the models and the observed pattern in the scatter plot. Students calculate and analyze residuals based on an interpretation of residuals as prediction errors.
