TEALS SNAP 0.5.pptx connect the dots?

[jdonwells]

The code on slide 8 is different from the code given by the link in the notes. https://snap.berkeley.edu/snap/snap.html#present:Username=aspiece%40gmail.com&ProjectName=Snap%20Coordinate%20System%20Intro

Slide 8 gives 4 points. The code on slide 8 has room for 4 points, but the code in the link has room for 5 points. Presumably, this is to draw 4 sides and connect the dots by initializing the pen to 0, 0 and then returning to 0, 0. Will the students know the intent of the extra go to x: y:?

Perhaps we should add a fifth coordinate of 0, 0 and remove the idea of initialization at this early point.
