What is a hackathon?

At CS4ALL hackathons, students from all over New York City are challenged work together to reimagine their communities and how technology gets used. Hackathons are ideal for honing new or familiar programming languages as students work in fresh and exciting environments, learning how to rapidly prototype ideas and create working demos, as well as develop and present their ideas to judges and other students.

Hack Packs are here!

Interested in organizing a hackathon for your school? The CS4ALL Hack Pack contains a teacher guide, student worksheets, day-of slideshow, and scoring rubric. All files are editable. Check out the Sugar Shoppe Hack Pack, the first we’ve shared publicly.
