Objectives

Computer Science Objectives

Students will explore one strategy for synchronizing interactions between sprites using “wait” blocks
Students will develop greater familiarity with the computational concept of events and parallelism and the practice of reusing and remixing
Students will become familiar with synchronizing interactions between sprites
Students will be able to explore how to adjust and fix timing in conversations in order to coordinate a synchronized conversation between sprites.

Language Objectives

Students will use knowledge of language and its convention to explain how the design of the Scratch project relates to personal interests
Students will use general and academic language to provide peer feedback in speaking and writing

Vocabulary

synchronization: coordinating actions between different sprites
event: An action that causes something to happen.
initialization: Assign an initial (beginning) value to an object (or variable).
sequence: A particular order of steps or events.

Standards

Computer Science
