What is a hackathon?

At CS4All hackathons, students from all over New York City are challenged to apply computer science concepts and practices they’ve learned in the classroom to solve real-world challenges using technology. Hackathons are great learning opportunities for students to focus on new or familiar programming languages like Scratch, Python, and JavaScript. Students have the opportunity to work in fresh and exciting environments, learn how to rapidly prototype ideas, and create working demos.

Here are recaps and pictures from our past hackathons.

Hack Packs are here!

Any school can host their own hackathon with the CS4All Hack Packs! Each Hack Pack contains a teacher guide, student worksheets, day-of slideshow, and scoring rubric. All files are editable.
