Hour of AI Activities for Elementary Students

If you’ve led the Hour of Code in your computer lab, you already know how much excitement one well-planned hour can create. This year the event has a new name and a new focus: the Hour of AI. It’s a chance to help students understand what artificial intelligence is, how it learns, and how to use it responsibly.

I’ve pulled together my favorite Hour of AI activities for elementary students, organized by grade band, plus unplugged options for classes without devices. Every idea here works in a 30 to 60 minute tech lab session.

Wondering whether this means coding is out? I shared my thoughts in Hour of Code Is Now Hour of AI. Does That Mean Coding Is Outdated? (short answer: no!).

What is the Hour of AI, and when is it?

The Hour of AI grew out of the Hour of Code, the event that has introduced millions of students to computer science since 2013. It connects with Computer Science Education Week each December, the week of Grace Hopper’s birthday on December 9. According to the Hour of AI FAQ, the activities are available year-round, and the most popular Hour of Code activities aren’t going anywhere.

That means you can do both. Pick an AI lesson for one class period and keep a coding favorite for another. Many tech teachers I know stretch it into a full week or even the whole month of December.

Hour of AI activities for K-2

With our youngest students, the goal is simple: AI is a tool that people build, it learns from examples, and it can make mistakes. Keep it concrete and hands-on.

• “Is it AI?” sort. Show pictures of a calculator, a smart speaker, a light switch, a video recommendation and a robot vacuum. Students decide together which ones “learn” and which just follow one instruction.
• Teach the robot. Students give a classmate “examples” of a shape or color, then test whether the “robot” can spot the next one. It’s a quick way to show that AI learns from the examples we give it.
• Ask a grown-up first. Talk about when it’s okay to use a talking assistant or AI app and why we check with a trusted adult.

If you want everything planned for you, my Artificial Intelligence Lessons Mini Unit for K-2 breaks these big ideas into hands-on lessons made for primary classrooms. It works for the Hour of AI, the Hour of Code, or a digital literacy unit. Pair it with the AI Friends Bulletin Board Kit, a set of friendly robot characters that keep the conversation going after the hour ends.

Hour of AI activities for grades 3-5

Upper elementary students are ready to look under the hood: how AI learns, how to ask it good questions, and why its answers still need checking.

• Prompt practice. Give students the same question worded three ways and compare the answers an AI tool gives. What made one prompt work better?
• Fact-check the robot. Share an AI answer that includes a mistake and have students find it using a trusted source. This is digital citizenship and research skills in one.
• Is it fair? Discuss what happens when an AI learns from examples that leave some people out. Fourth and fifth graders have strong opinions here!

My Artificial Intelligence Mini Unit for Grades 3-5 covers all of these in 4 lessons: how AI learns, prompt engineering, fact-checking responses, and fairness in AI systems, with lesson plans, editable slides and vocabulary. For a single class period, the Artificial Intelligence Lesson and Activity includes a short history of AI, 10 facts, 10 vocabulary words and a realistic fiction story with comprehension questions.

To keep students talking, use the Coding, Robotics, and AI Discussion Prompts, 42 printable cards for warm-ups or exit tickets. The Artificial Intelligence Vocabulary Posters give every grade kid-friendly definitions to point to.

Unplugged Hour of AI activities (no devices needed)

No Chromebooks that day? AI literacy works beautifully unplugged.

1. Human pattern finder. Sort a stack of picture cards into two groups without telling students the rule. They guess the pattern, just like a model finding patterns in training data.
2. Recommendation game. Students list three favorite books or shows, then a partner “recommends” a fourth. Talk about how apps make the same kind of guess.
3. AI or not, around the school. Walk the building (or look at photos) and spot technology that uses AI and technology that doesn’t.
4. Write the rules. Students write step-by-step instructions for a simple task, then compare that to how AI learns from examples instead of rules. This is a great bridge back to coding.

An AI bulletin board makes the week visible to the whole school. The Our AI World Bulletin Board Kit shows students where artificial intelligence shows up in everyday life.

Want a ready-made unplugged lesson? My free Coding in the Classroom Starter Kit includes a From Coding to AI section with AI word wall cards and a screen-free sorting lesson where students help Dot the robot sort shapes by a rule, just like a computer learns from examples.

Keep coding in the mix

AI tools can write code, but students still need to understand how instructions, sequences and debugging work. I plan at least one coding day during Computer Science Education Week. These are my December favorites:

• Christmas Coding Digital Interactive Activities for grades 2-5, fully digital in Google Slides or PowerPoint
• Code a Character, directional coding that doubles as keyboard shortcut practice
• Pixel Art Coding, 3 unplugged lessons that mix art and math
• Unplugged Coding Fairy Tales Bundle for grades 1-4
• Hour of Code Bundle of K-5 Activities and Decor if you want the whole week planned, decor included

Planning tips for your Hour of AI week

• Start with vocabulary. A few shared words (artificial intelligence, data, pattern, prompt) make every later conversation easier.
• Go unplugged first. An offline activity before students touch an AI tool helps them understand what is happening behind the screen.
• Check your school’s AI policy. Many AI tools have age limits, so younger students may do best with teacher-led demos.
• Read directions aloud. It levels the playing field for early readers and keeps the whole class at the same pace.
• Let families in. A quick note home about what students learned extends the conversation beyond the lab.

Hour of AI FAQ

Is the Hour of Code gone?

No. The Hour of AI builds on the Hour of Code, and the most popular Hour of Code activities are still available.

When is the Hour of AI?

It connects with Computer Science Education Week each December, but the activities can be used any time of year.

Can kindergarten students do the Hour of AI?

Yes. Focus on concrete ideas, like sorting examples and talking about what AI is, and keep any AI tool use teacher-led.

Do students need devices?

No. Many of the best Hour of AI activities for elementary students are unplugged, like pattern sorting and recommendation games.

How long should an Hour of AI lesson be?

About one class period. Many tech teachers spread activities across the whole week so every grade gets a turn.
