The Signal

In this collaboration between Cartoon Network and CS First, students tell a story using the characters from "The Amazing World of Gumball." This activity introduces students to computer science and the programming language Scratch. It is appropriate for students ages 10-13 and takes 40-75 minutes to run. To use this activity for more than one class, create a club so students can save their Scratch projects ( When returning to the activity, students should go to and navigate to the last video they watched.
