3-5 Computer Science - Green - Unit 4 Synchronization

green cat

In the final unit, students will investigate the computer science concept of synchronization through the Use - Modify - Create framework by first being introduced to the concept through a variety of multimodal activities, then exploring it in Scratch before creating their own original Storytelling project in Scratch incorporating this concept. Students will also collaborate on computational artifacts, debug problematic programs, provide feedback on each other's work, and reflect on their own progress throughout the unit.

Lesson Overview

Students will begin the creation of a Storytelling project in Scratch that will show their understanding of synchronization.  In this first lesson of a three lesson sequence, students will plan out their Storytelling project on paper using a planning guide, then begin building their project using Scratch.

 

Agenda

  1. โญ๏ธ Introduce: Storytelling Projects in Scratch (5 min.)

  2. ๐Ÿ’ฅ Mini-Lesson: Using Pair Programming to collaboratively work on a project (5 min.)

  3. ๐Ÿ“ Plan: Storytelling project on paper in pairs (15-20 min.)

  4. ๐Ÿšง Build: Storytelling project in Scratch in pairs (15-25 min.)

  5. ๐Ÿ““ Reflect: (5 min.)

    • How did the planning guide help you start your project in Scratch?

    • What are you excited to add to your Storytelling project next class?

Materials

  • computing devices for all students

  • Storytelling Planning Guide, printed

  • Green Level Student Workbooks, p. 17

  • Storytelling Scratch studio (teacher-created)

Lesson Overview

Students will continue the creation of a Storytelling project in Scratch that will show their understanding of synchronization. In this second lesson of a three lesson sequence, students will continue building their project using Scratch, then pause to provide feedback in small groups on each other's Storytelling projects, using that feedback to revise and finalize their work.

 

Agenda

  1. ๐Ÿ’ซ Review: Using synchronization to create a Storytelling project in Scratch (5 min.)

  2. ๐Ÿ’ฅ Mini-Lesson: Synchronization in Scratch: switching between 2 sprites to synchronize "say" and "wait" blocks (5 min.)

  3. ๐Ÿšง Build: Storytelling project in Scratch in pairs (30-45 min.)

  4. ๐Ÿ“ฌ Peer Feedback: Providing positive and constructive feedback on 2 peer projects (15 min.)

  5. ๐Ÿ““ Reflect: (5 min.)

    • What did you get stuck on while working on your project? How did you persevere?

    • What did you learn from your classmates' projects feedback?

    • What did you discover from looking at other projects?
