Build a Teachable Machine Image Classifier With Your Kid

Introduce your child to the fundamentals of machine learning by building a custom, web-based image recognition model in thirty minutes.

Children today are surrounded by artificial intelligence, from video recommendation algorithms to voice assistants. However, most children only interact with AI as passive consumers. To prepare them for a technology-driven future, they need to understand how these systems actually work. The best way to demystify AI is to have them build a functional model themselves. By using a free, web-based tool, you can help your child train a computer to recognize real-world objects in real time.

This hands-on project is designed for children aged 8 to 16 and requires no coding experience, no paid subscriptions, and no specialized hardware. All you need is a computer with a webcam and an internet connection. Together, you will build an image classifier that can distinguish between different objects, such as a healthy snack versus a sweet treat, or different hand gestures. This exercise provides a clear, tangible demonstration of how computers learn from data.

Choosing Your Project: The Healthy Snack Classifier

Before opening the software, decide on a fun classification task. A highly engaging and visual project is the "Healthy Snack versus Sweet Treat" classifier. Gather two distinct items from your kitchen: an apple or banana to represent the healthy snack, and a cookie or candy bar to represent the sweet treat. This simple setup makes it easy for the webcam to capture clear, contrasting visual data.

Step-by-Step Guide to Building the Model

Follow these steps with your child to build, train, and test your custom image classifier:

• Access the Platform: Open a web browser on your computer and navigate directly to the Google Teachable Machine website. Click on the "Get Started" button, then select "Image Project" followed by "Standard Image Model."
• Create and Label Your Classes: You will see two default boxes labeled "Class 1" and "Class 2." Have your child rename "Class 1" to "Healthy Snack" and "Class 2" to "Sweet Treat." These labels represent the categories the computer will try to identify.
