Hello Ruby is the world's most whimsical way to learn about computers, technology, programming, and mathematics. The story started with a book, and now Ruby continues her adventures in digital exercises, outdoor playground activities, and videos. It's suited for kids age 5 years and older (but even adults might learn something new).
