Mathalicious: Key Board
Mathalicious

In this lesson students apply geometric transformations to build (and play) their own video games.

Mathalicious: Transformers
Mathalicious

In this lesson, students identify and categorize the different transformations that occur when a user manipulates a smartphone screen.

Mathalicious: The Sound of Silence
Mathalicious

In this lesson, students use transformations of trigonometric functions to explore how sound waves can interfere with one another, and how noise-canceling headphones use incoming sounds to figure out how to produce that sweet, sweet silence.
