Scratch 3: coding logic walkthrough

Section role: supports the 'Decoding the Logic of Coding' section as the teacher formalizes core programming concepts, building upon the students' earlier hands-on exploration. Slides: (1) Title — 'Bringing Your Story to Life with Code'; (2) The Story's Stage — visual of the Scratch Stage, explanation of its purpose as the animation area, connecting to 'where it happens'; (3) Your Digital Actors — visual of the Sprite List, defining sprites as characters, connecting to 'the actors'; (4) Giving Instructions: The Script Area — visual of the Script Area, explaining it's where instruction blocks are placed to form a sequence; (5) The Starting Signal: Events Blocks — visual examples of common Event blocks (e.g., 'when green flag clicked'), defining them as triggers or 'the When'; (6) Making it Move: Motion Blocks — visual examples of common Motion blocks (e.g., 'move 10 steps', 'turn 15 degrees'), defining them as controls for movement or 'the How'; (7) What It Says and Looks Like: Looks Blocks — visual examples of common Looks blocks (e.g., 'say Hello!', 'switch costume to'), defining them as controls for appearance and speech or 'the What'; (8) The Power of Sequence — graphic showing blocks stacked in a specific order, explaining how sequence dictates the story's flow and why order matters ('What happened if you put the 'Say' block before the 'Move' block?'). Concrete examples: 'when green flag clicked', 'move 10 steps', 'say Hello!', 'next costume'. Hooks back to the lesson: references the 'Design Teams' challenge from Section 2 and sets up the need for clear sequencing for the 'Script Master Quiz' in Section 4. Closing slide: 'How does telling a story digitally require a clear sequence of instructions?'
