I have a question about a project I will be starting shortly with 5th graders using MW EX to create a tessellation using simple polygons.  It is a question regarding teaching about angles.  When programming a turtle to create a triangle (for example) the relevant angle is the amount the turtle has to turn to create the triangle (the outside angle).  However when math is taught, usually the focus is on the internal angle.  As well one way to determine whether a shape can tessellate is to measure whether the place where the tessellated shapes meet equals 360 degrees.  If anyone can help me think this through that would be great.  If it is not clear what it is that I am asking,  please let me know.
thanks
