Scratch, the MIT Media Lab project, lays the foundation for exploratory learning in computer science. Our customized curriculum expands on the Scratch platform to engage Coder Kids in coding activities that reflect their unique interests. In Introduction to Scratch, Coder Kids learn about programming concepts including variables, conditionals, control statements, and events. These concepts are mastered through the completion of projects, including creating a dance party, writing a story, creating user quizzes, and making their own video games.
