Build a Teachable Machine Image Classifier With Your Kid

A hands on weekend project to demystify computer vision and machine learning.

Children today are surrounded by artificial intelligence, yet they rarely get to see behind the curtain. Most AI interactions are passive, such as chatting with a bot or watching recommended videos. To truly prepare the next generation for an AI driven world, we must help them transition from consumers to creators. This weekend project allows you and your child (ages 8 to 16) to build and train a custom image recognition model in fifteen minutes using a free tool developed by Google.

By using your computer webcam, your child will train a neural network to recognize different objects, hand gestures, or facial expressions. There is no coding required, no paid subscriptions, and no complex software to install. All you need is a web browser and a curious mind.

Step 1: Set Up Your Lab

To begin, sit down with your child at a computer equipped with a working webcam. Gather two or three distinct objects from around the house. Excellent choices include:

• Two different action figures or stuffed animals.
• A coffee mug versus a water bottle.
• Your hand showing a "thumbs up" versus a "peace sign."

Once you have your objects, open your web browser and navigate directly to the Google Teachable Machine website at https://teachablemachine.withgoogle.com/ . Click on "Get Started" and select "Image Project," then choose the "Standard Image Model."

Step 2: Gather Your Training Data

On the screen, you will see two default categories called "Class 1" and "Class 2." Think of these as the folders where your AI will store its visual memories. Have your child rename these classes to match your chosen objects (for example, "Stuffed Bear" and "Toy Car").

Now, click the "Webcam" button under the first class. Hold your first object up to the camera. Instruct your child to click and hold the "Hold to Record" button. As the camera captures images, tell your child to slowly rotate the object, move it closer and further away, and tilt it in different directions.
