Encouraging students to learn and use official computer science terms will enable them to communicate correctly and efficiently with others and builds their knowledge such that it can be further developed without having to relearn terms and concepts at a later time. The terms and concepts used in the unplugged lessons are defined using words that young students can understand.
Best practice is to introduce the terms with easy-to-understand language, relate the terms to previous experiences, use the terms repeatedly beyond the lesson itself throughout the entire course (and in other situations) when appropriate, and reinforce students’ use in oral and written communication.
The following terms are introduced in an unplugged lesson as either a vocabulary word or as a term related to the online Blockly programming interface. Terms are subsequently reinforced in the following online puzzles and activities. Most terms appear multiple times throughout the courses and lessons providing the students with many opportunities to deepen their understanding and assimilate the words into conversations, both in and outside of the classroom.
A simplified representation of something more complex.
The design of products, devices, services, or environments taking into consideration the ability for all users to access, including people who experience disabilities or those who are limited by older or slower technology.
A list of steps to finish a task.
A way of representing information using only two options.
The two options used in your binary code.
A contraction of "Binary Digit". A bit is the single unit of information in a computer, typically represented as a 0 or 1.
block-based programming language
Any programming language that lets users create programs by manipulating “blocks” or graphical programing elements, rather than writing code using text. Examples include Code Studio, Scratch, Blockly, and Swift. (Sometimes called visual coding, drag and drop programming, or graphical programming blocks)
The visual programming language used in Code.org's online learning system for K-5 students.
An error in a program that prevents the program from running as expected.
The most common fundamental unit of digital data eg. Kilobyte, Megabyte, etc. A single byte is 8 bits-worth of data.
call (a variable)
Use a variable in a program.
call (a function)
This is the piece of code that you add to a program to indicate that the program should run the code inside a function at a certain time.
Press the mouse button.
The language that programmers create and use to tell a computer what to do.
An instruction for the computer. Many commands put together make up algorithms and computer programs.
Modifying a problem in such a way that it can be modeled or solved using a computer or machine.
Strategies include: decomposition, pattern matching, abstraction, algorithms.
Using the power of computers to solve problems.
Statements that only run under certain conditions.
Getting help from a large group of people to finish something faster.
Doing something on the internet, usually again and again, to make another personal feel angry, sad, or scared.
Information. Often, quantities, characters, or symbols that are the inputs and outputs of computer programs.
Finding and fixing problems in an algorithm or program.
Break a problem down into smaller pieces.
define (a function)
Figure out the details of the problems that you are trying to solve.
Someone who acts safely, responsibly, and respectfully online.
The information about someone on the Internet.
DNS (domain name service)
The service that translates URLs to IP addresses.
Press the mouse button very quickly.
Click your mouse button and hold as you move the mouse pointer to a new location.
Release your mouse button to "let go" of an item that you are dragging.
A method of sending information using telephone or television cables.
An action that causes something to happen.
A monitor for a specific event or action on a computer. When you write code for an event handler, it will be executed every time that event or action occurs. Many event-handlers respond to human actions such as mouse clicks.

fiber optic cable
A connection that uses light to transmit information.
A loop with a predetermined beginning, end, and increment (step interval).
Feeling annoyed or angry because something is not the way you want it.
A piece of code that you can easily call over and over again.
The piece of code that you add to a program to indicate that the program should run the code inside a function at a certain time.
The code inside a function that instructs the program on what to do when the function is called.
The common programming structure that implements "conditional statements".
A way to give information to a computer.
A group of computers and servers that are connected to each other.
A number assigned to any item that is connected to the Internet.
A repetitive action or command typically created with programming loops.
The action of doing something over and over again.
Connected to the Internet.
A way to get information out of a computer.
Small chunks of information that have been carefully formed from larger chunks of information.
Finding similarities between things.
An extra piece of information passed to a function to customize it for a specific need.
Trying again and again, even when something is very hard.
Short for "picture element", the fundamental unit of a digital image, typically a tiny square or dot that contains a single point of color of a larger image.
An algorithm that has been coded into something that can be run by a machine.
The art of creating a program.
To do something again.
Cause the computer to execute the commands you've written in your program.
A program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.
Computers that exist only to provide things to others.
The tall grey bar in the middle section of Code.org's online learning system that contains all of the commands you can use to write your program.
Able to be relied on as honest or truthful.

An easy-to-remember address for calling a web page (like www.code.org).
A name you make up so that you can see or do things on a website, sometimes called a “screen name.”
A placeholder for a piece of information that can change.
A collection of interlinked web pages on the World Wide Web.
A loop that continues to repeat while a condition is true.
