Logo Math Wiki - Learning Mathematics through Programming
This wiki contains a series of Turtle Math lessons. While many folks might recall learning about Logo in the 1970's or the 1980's, it is one of the most effective computer environments for learning the basics of shape and measurement. Accurate planning and writing of Logo code requires a practical and first hand knowledge of right triangle mathematics. The following series of lessons will challenge learners of all ages.
Note that the graphics for my lessons were taken on either a Mac or PC running
