Looking for a gentle, self-paced introduction to Bootstrap? Try the Hours of Code below. No prior programming experience required!

Hour of Data

This Hour of Data lesson is a self-guided Desmos activity. Students explore data visualization, introductory programming using The Pyret Programming Language, and the application of Data Science to solve real problems. Students will investigate a data set of vehicle-wildlife collisions in Vermont and make recommendations about where to build wildlife overpasses.

Image Composition!

This Hour of Code lesson introduces students to image-producing functions, defining values and image placement using coordinates. A series of scaffolded student-paced activities in our Parley editor build student skills to the point that they’ll be ready to modify code in a Pyret starter file to build a snowman scene at the end!

Intro to Graphics

This Hour of Code lesson is a great, self-paced activity to introduce students to Bootstrap. Students explore simple function composition and order of operations in WeScheme, and then build on that knowledge to create simple computer graphics.
