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.
