To be literate in a society where the information shared online is often exploited, learners should be exposed to multiple aspects of contemporary predictive modeling. Explore a lesson in which students learned an algorithm used in practice to automate the process of making recommendations.
Inspired by epidemic curves, this class developed a spreadsheet model of an epidemic to compare outcomes with and without protective measures.
During a Desmos activity, students adjust the measures of angles in radians to reposition a laser and a mirror so the beam passes through three stationary targets. The Radian Lasers activity can be extended to simulate project-based learning.
Show your students how useful mathematics can be in real-world applications.

This article presents an example of discovering an idea through creative play. After some trial and error, I drew a wonderful image, which I later learned was a two-dimensional view of a four-dimensional shape called tesseract.
Examining the covariation of triangle dimensions and area offers a geometric context that makes analyzing a piecewise function easier for students.
