Activities

The award-winning Sugar Learning Platform promotes collaborative learning through Sugar Activities that encourage critical thinking, the heart of a quality education. Designed from the ground up especially for children, Sugar offers an alternative to traditional “office-desktop” software.
Sugar is the core component of a worldwide effort to provide every child with equal opportunity for a quality education. Available in 25 languages, Sugar’s Activities are used every school day by one-million children in more than forty countries.
Originally developed for the One Laptop per Child XO-1 netbook, Sugar runs on most computers. Sugar is free/libre and open-source software.
