What is MicroWorlds?

MicroWorlds is Logo-based computer software that allows students to explore fundamental mathematics concepts in an environment that fosters creativity and experimentation. Students direct a "turtle" around the screen using the keyboard commands which make up the Logo computer language. Lines of Logo commands can be combined into procedures (programs) that can be used to build complex shapes, designs, games and simulations. MicroWorlds provides students with an almost limitless environment for learning.
