Type: Lesson/Unit Plan

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.

Content Standard(s):
Digital Literacy and Computer Science
DLIT (2018)
Grade: 6
8) Create a program that initializes a variable.

Example: Create a flowchart in which the variable or object returns to a starting position upon completion of a task.

Unpacked Content
Evidence Of Student Attainment:
Students will:
  • create a variable set to a specific value within a program that will change during the program but will reinitialize or return back to the specific value initially set when the program is run again.
Teacher 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.

Grade: 7
7) Create a program that updates the value of a variable in the program.

Examples: Update the value of score when a coin is collected (in a flowchart, pseudocode or program).

Evidence Of Student Attainment:
Students will:
  • create a variable whose value changes during their program.
Teacher 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.

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

Examples: Make a game, interactive card, story, or adventure game.

Evidence Of Student Attainment:
Students will:
  • create a properly functioning program using selection, iteration, abstraction, that initializes and updates at least two variables.
Teacher 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.
