Computer Science Discoveries Unit 3 Chapter 1 Lesson 8: The Counter Pattern Unplugged (18-19)

Subject Area

Digital Literacy and Computer Science

Grade(s)

6, 7, 8

Overview

This unplugged lesson explores the underlying behavior of variables. Using notecards and string to simulate variables within a program, the class implements a few short programs. Once comfortable with this syntax, the class uses the same process with sprite properties, tracking a sprite's progress across the screen.

DLCS18.6.8

Create a program that initializes a variable.

Unpacked Content

UP:DLCS18.6.8

Vocabulary

  • initialize

Knowledge

Students know:
  • that updating a variable during a program changes the initial value set, so variables need to be initialized (set to the original value) at the start or end of a task or program.

Skills

Students are able to:
  • set variables back to their original values upon start
  • up or completion of a task or program.

Understanding

Students understand that:
  • variables need to be initialized for programs to work properly more than once.
Digital Literacy and Computer Science (2018) Grade(s): 7

DLCS18.7.7

Create a program that updates the value of a variable in the program.

Unpacked Content

UP:DLCS18.7.7

Vocabulary

  • program
  • value

Knowledge

Students know:
  • how to update variables throughout their programs.

Skills

Students are able to:
  • write complex programs where variables can be changed while a program is running.

Understanding

Students understand that:
  • variables can be changed while a program runs.
  • changes to variables could trigger other events within a program.

DLCS18.8.7

Create a program that includes selection, iteration, or abstraction, and initializes, and updates, at least two variables.

Unpacked Content

UP:DLCS18.8.7

Vocabulary

  • selection
  • iteration
  • abstraction
  • initialize
  • variables

Knowledge

Students know:
  • how to write a program that includes selection, iteration, abstraction, initialization, and updates variables.

Skills

Students are able to:
  • write a program that includes foundational programming concepts
  • selection, iteration, abstraction, initialization, and updating variables.

Understanding

Students understand that:
  • they have the ability to create and design programs they may have never considered themselves able to do so.
