CS4U is a free, fun computer science program for elementary students. The program features lectures, presentations, hands-on group activities, and independent practice. The big takeaway of this class is that computers will not be used.

We are a non-profit organization led by high school students who are passionate about teaching computer science to young students. We arrange workshops and programs with multiple sessions in a couple of San Jose libraries to teach theoretical computer science, such as computer number systems, Boolean Algebra, Basic Data Structures, and Graph Theory.

Members of CS4U are also eligible to attend an International Computer science competition.
