Khan Academy and Pixar Studios have teamed up to create Pixar in a Box, a series of free online tutorials that demonstrate how STEM and the arts are used in film animation. Each tutorial focuses on the use of a concept learned in school and starts with a design-challenge lesson (for Grades 5+), followed by several different grade-appropriate lessons focused on particular math concepts.  Topics include:  Effects, Patterns (randomness), Rigging (controls), Animation (curves), Environmental Modeling (parabolic arcs), Character Modeling (weighted averages), Crowds (combinatorics), Sets & Staging (geometric transformations), and Rendering (algebra).
