Words Worth Knowing

Age-appropriate AI definitions with clear examples. Filter by audience to find the right level.

K–2 Ages 5–7

Simple words for young learners. Every term includes a short example.

AI

A smart tool that follows rules people wrote to help with tasks.

Example: A voice helper on a phone uses AI to answer questions.

Tool

Something that helps us do a job. Pencils, calculators, and apps are all tools.

Example: A calculator is a tool that helps with math.

Helper

Something or someone that makes a task easier or faster.

Example: Spell-check is a helper that finds spelling mistakes.

Prompt

The words we give the computer to tell it what to do.

Example: "Draw me a red dog" is a prompt.

Check

To look again and make sure something is right before using it.

Example: We check an answer with a book or a trusted grown-up.

Choice

When we decide what to do. People always make the important choices.

Example: You choose what to ask and what to do with the answer.

Machine

A device that does work. Computers and phones are machines.

Example: A washing machine washes clothes so people don't have to by hand.

Rule

Instructions that tell a machine what to do and how to do it.

Example: A stop sign is a rule — it tells drivers what to do.

Grades 3–5 Ages 8–10

Concrete definitions with everyday examples for upper elementary learners.

Artificial Intelligence (AI)

A type of program that uses patterns from lots of examples to answer questions or help with tasks.

Example: AI helps apps recognize your face or suggest what video to watch next.

Pattern

Something that repeats in a predictable way. AI learns by finding patterns.

Example: AI noticed that people who like one song often like similar songs.

Prompt

The question or instruction you give an AI tool. Clearer prompts give better answers.

Example: "List 3 facts about wolves" is a prompt.

Data

Information. AI uses huge amounts of data to learn how to respond.

Example: Millions of photos helped AI learn what a cat looks like.

Mistake

When AI gives a wrong or confusing answer. It happens — that's why we check.

Example: AI once said a fish could live on land. It couldn't — that was a mistake.

Check

Looking at an answer again to see if it makes sense before using it.

Example: You check an AI answer the same way you'd check with an encyclopedia.

Tool

Something that helps you get a job done. AI is a digital tool.

Example: A calculator is a tool for math. AI is a tool for information and writing.

Idea

A starting point for thinking. AI can give you ideas, but your thinking comes first.

Example: AI gave three ideas for a story. You picked one and wrote it yourself.

Grades 6–8 Ages 11–13

Vocabulary for understanding how AI works and using it responsibly.

Artificial Intelligence

A computer system that uses data and patterns to generate responses or complete tasks.

Example: ChatGPT uses AI to generate text responses to your questions.

Generative AI

AI that creates new content — text, images, code — based on a prompt.

Example: Ask AI to write a poem and it generates one. That's generative AI.

Bias

When AI outputs favor certain groups, viewpoints, or results due to patterns in training data.

Example: If AI was trained mostly on one type of writing, it may write in that style more often.

Fact-check

Verifying information by checking it against reliable sources. Required with AI content.

Example: AI said a volcano erupted in 1940. You checked a reliable source — it was 1980.

Responsible use

Using AI in ways that support learning, follow school policies, and respect others.

Example: Using AI to brainstorm, then writing the report yourself.

Prompt

The instruction or question you give an AI. Better prompts lead to more useful responses.

Example: "Summarize photosynthesis for a 7th grader in 3 sentences" is a clear prompt.

Integrity

Acting honestly and consistently with your values, even when no one is checking.

Example: Telling your teacher you used AI is part of integrity.

Original work

Work that reflects your own thinking, ideas, and effort — with or without AI support.

Example: An essay where you used AI to brainstorm but wrote and edited it yourself.

Grades 9–12 Ages 14–18

High school vocabulary for ethics, prompting, and critical evaluation of AI.

Algorithm

A set of rules a computer follows to complete a task or make a decision.

Example: The algorithm that decides what content appears in your social media feed.

Machine Learning

A type of AI where systems learn patterns from data rather than following fixed rules.

Example: Email spam filters learn to identify spam by studying thousands of spam examples.

Bias

Systematic patterns in AI that favor or disadvantage certain groups or perspectives.

Example: Facial recognition tools have shown lower accuracy for darker skin tones due to training data bias.

Authorship

Who created or is responsible for a piece of work. Complicated when AI contributes.

Example: If AI wrote 80% of your essay, questions about authorship are real and important.

Citation

Crediting a source for ideas or content that isn't yours — including AI-generated content.

Example: "This section was drafted with assistance from ChatGPT and revised by the author."

Credibility

Whether a source or claim can be trusted. AI output is not automatically credible.

Example: AI cited a study that doesn't exist. That's a credibility problem.

Disclosure

Being transparent about how AI was used in creating work.

Example: A student noting in their project that AI was used to generate an outline.

Oversight

Human review and judgment applied to AI outputs before acting on or sharing them.

Example: Reading and editing every AI-drafted sentence before submitting it as work.

Higher Education College & Adult

Professional and academic vocabulary for AI literacy in higher education contexts.

Large Language Model (LLM)

A type of AI trained on massive amounts of text to predict and generate language.

Example: GPT-4, Claude, and Gemini are all large language models.

Hallucination

When an AI confidently generates false information that sounds plausible.

Example: AI cited a real journal but fabricated the article title, authors, and conclusions.

Prompt engineering

The practice of designing effective prompts to guide AI toward useful, targeted outputs.

Example: Specifying format, audience, length, and context in a prompt is prompt engineering.

Training data

The text, images, or other data used to teach an AI model how to respond.

Example: LLMs are trained on books, websites, and other text from across the internet.

Token

A unit of text (roughly a word or word fragment) that LLMs process one at a time.

Example: The word "learning" is one token. "AI" is one token. "unbelievable" might be 3 tokens.

Context window

The amount of text an AI model can "see" and consider at one time.

Example: A model with a small context window forgets earlier parts of a long conversation.

Academic integrity

Using AI in ways that are honest, transparent, and consistent with course expectations.

Example: Following a professor's AI policy and disclosing any AI assistance in submitted work.

Critical oversight

Applying expert judgment to review, verify, and take responsibility for AI outputs.

Example: A researcher using AI to summarize sources and then verifying every claim against originals.

Educators Teaching & Implementation

Terms useful for educators designing AI literacy instruction.

AI Literacy

The ability to understand, use, evaluate, and make decisions about AI in an informed way.

Example: Teaching students to fact-check AI outputs is a component of AI literacy.

Generative AI

AI that produces new content — text, images, code, audio — based on input.

Example: Voice assistants like Siri and Alexa use AI to understand what you say and respond.

Generative AI

A type of AI that creates new text, images, or other content based on what you ask it.

Example: When a student asks an AI tool to write an essay, that's generative AI in action.

Prompt

The question or instruction a person types to an AI tool.

Example: Typing "Give me 5 ideas for a birthday party" into an AI tool is a prompt.

Hallucination

When AI confidently gives an answer that sounds right but is actually wrong.
