AI 3rd-4th Grade

How Computers Learn

Just like you learn from examples and practice, computers can learn too! This is called Machine Learning.

Meet DataBot!

DataBot is a computer program that can learn to recognize things. Help DataBot learn to identify fruits!

How Machine Learning Works

🔍

1. Look at Examples

🧩

2. Find Patterns

✅

3. Practice & Test

🚀

4. Make Predictions

Let’s Explore Each Step!

🔍 Step 1: Look at Examples

In this step, we show the computer many examples to learn from – just like how you learn by seeing many examples!

Label: Cat

Label: Dog

These examples teach the computer: “This is what cats look like, and this is what dogs look like.”

Mini Quiz:

How do computers learn?

By studying lots of examples and finding patterns

By reading books

By watching YouTube videos

Data & Information

Data is like the food that helps AI grow smart! It’s made up of facts, numbers, and information that computers can understand.

What is Data?

🔢

Numbers

🔤

Words

📸

Pictures

🎵

Sounds

🔢 Numbers as Data

Computers love numbers! They use numbers to count, measure, and calculate things.

Examples of Number Data:

Temperature readings: 72°F, 22°C
Scores in games: 95 points
Measurements: 5 feet tall
Counting things: 27 students in class

How AI Uses Numbers: AI can analyze temperature patterns to predict weather, or look at your test scores to suggest what you might need to study more.

Try it! Enter some numbers and see what the computer does with them:

AI and Coding Together

AI can help us with coding! It can suggest code, find errors, and even write simple programs.

Example: Teaching a computer to recognize animals

Here’s some simple code that an AI might use:

if (has_fur == true) {
    if (makes_sound == "Meow") {
        animal = "Cat";
    }
} else if (has_fur == true) {
    if (makes_sound == "Woof") {
        animal = "Dog";
    }
} else if (has_scales == true) {
    animal = "Fish";
}

Try it: What animal would the computer guess if:

has_fur = true, makes_sound = “Meow”

Read the code and make your prediction!

AI Ethics for Kids

As we use AI more and more, it’s important to think about how to use it wisely and kindly.

Being Kind Online

Scenario 1: Chatbot Friend

You’re chatting with an AI chatbot. What’s the kindest way to talk to it?

Ask questions politely and say thank you when it helps you

Say mean things because it’s just a computer and doesn’t have feelings

Scenario 2: AI Art Creator

You’re using an AI to create art for your school project. What should you do?

Tell your teacher that AI helped you create the art

Pretend you drew everything yourself by hand

Choose the best option in each scenario!

Truth vs. Fiction Online

AI can sometimes make mistakes or create things that aren’t real. Let’s practice spotting what’s true!

🦄

AI says: “Unicorns are real animals that scientists discovered in 2020.”

🌧️

AI says: “Water evaporates from oceans, forms clouds, and falls as rain.”

AI Ethics Rules for Kids:

Be kind when using AI – treat it with respect
Always check if information is true with trusted adults
Never share personal information with AI
Give credit when AI helps with your work
Remember that humans should make important decisions, not just AI
