Lesson Overview

With the understanding that coding is only one aspect of Computer Science, students will have their first opportunity to explore Scratch in this lesson. In partners, they explore the project editor and coding blocks using a code comprehension protocol called TIPP & SEE.

Agenda (updated)

🔥 Warm-up: Review Computer Science Norms. What do you remember about computer science from previous grades? If this is your first time learning computer science, how are you already using computers to be creative?
▶️ Main Activity: Watch Scratch Overview video. Model the TIPP & SEE Protocol with the Scavenger Hunt - Under the Sea project. In partners, students complete a hardcopy or Google Form activity page then continue to make changes to the Under the Sea program to personalize it.
🤔 Debrief: How did you and your partner change the project to make it more “you”? What is something you can thank your partner for today?
