Begin the session with a brainstorm. Ask: "What is computer coding?" Listen to several ideas before sharing the definition that coding is a specific way to write instructions that a computer can understand. Next, ask the group to brainstorm technology that requires coding. Ask students how they feel about coding. Are they interested in it? As a group, watch the video What Most Schools Don’t Teach
If there are no computers available for students, you can do this project by choosing an Hour of Code activity that does not require technology. Browse a collection of these no-tech activities on the CS Fundamentals Unplugged
Do you have absolutely no experience with coding? That's fine, because no experience is necessary. You can learn alongside members. Throughout this project, it’s OK to answer members’ questions with "I don’t know. Let’s figure it out together." You can also encourage members to ask each other questions and work together through the tricky bits. This attitude helps support the collaborative vibe that is essential to computer science communities.
