They also have     7     whole lot of really fun hands-on interactive activities, where families and students can create     8     (they) own game or app using the resources that Code. org offers.”

The creators of Code. org have a mission of     9     (get) computer science into the hands of students, teachers, and educators to help build a general     10     (understand) .
