Library of Virtual Manipulatives

Turtle Geometry
Turtle Geometry allows students to program the movements of a turtle to get to a certain point, through a particular obstacle or to match a certain shape. It also provides a blank work space so a teacher can set up a specific challenge or so students can challenge each other. The student must plan ahead and think about what they want to tell the turtle to do. For example, they can tell the turtle to turn left or right and how many degrees they want it to turn and they can also provide inputs for movement form 1 to 5 spaces. This was an interesting manipulative and I can see benefits in this however, I don't see this as one of the better mathematical manipulatives.
