Lesson 19

Conversation

In this lesson, students will learn to synchronize interactions between sprites to create conversations for their story.

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 create an open-ended Scratch project using events and practice reusing and remixing

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

Standards

Computer Science

CSTA 1B-AP-10: Create programs that include sequences, events, loops, and conditionals
CSTA 1B-AP-13: Use an iterative process to plan the development of a program by including others' perspectives and considering user preferences.
CSTA 1B-AP-15: Test and debug a program or algorithm to ensure it runs as intended.

English Language Arts

ELA L.3.3: Use knowledge of language and its conventions when writing, speaking, reading, or listening.
ELA L.3.6: Acquire and use accurately grade-appropriate conversational, general academic, and domain-specific words and phrases, including those that signal spatial and temporal relationships.
ELA RI.3.5: Use text features and search tools (e.g., key words, sidebars, hyperlinks) to locate information relevant to a given topic efficiently.
ELA SL.3.4: Report on a topic or text, tell a story, or recount an experience with appropriate facts and relevant, descriptive details, speaking clearly at an understandable pace.
