Explore: Loops
Lesson Overview
Students will first use, then modify, a project exploring loops in Scratch using the TIPP & SEE model.
This will provide students with another opportunity to tinker with this concept in Scratch before starting an open-ended project in the next lesson.
Agenda
💫 Review: Use the pages in the Green Workbook to gain a deeper understanding of loops. (5-10 min.)
🚀 Explore: TIPP & SEE Repeat Loops: Animal Parade Scratch activity (35-50 min.)
📓 Reflect: (5 min.)
How did the Animal Parade program help you understand loops in computer science?
How would you explain loops to another person?
Can you think of a loop that happens in your life? What are they?
