Consider greenfoot as a combination between a framework for creating two-dimensional grid assignments in Java and an integrated development environment (class browser, editor, compiler, execution, etc.) suitable for novice programmers. While greenfoot supports the full Java language, it is especially useful for programming exercises that have a visual element. In greenfoot object visualisation and object interaction are the key elements.

Squeak Etoys

Children use Etoys to make their own models, stories, and games, which keeps them engaged because it's a lot of fun. But Etoys isn't just child's play. It's a highly effective way to teach math, science, and language arts, although many children won't realize this. Instead they'll stay immersed in discovery, reaching eagerly for each new idea, making their lessons more meaningful than with a 'face-front' approach.
