[IAEP] 40 maths shapes challenges

[Bill Kerr]

introduced turtle art and barry newell's 40 shapes to my students today
about half way through the lesson someone asked, "how do you do the circle?"

before I could say anything another student replied, "that's easy - just use
arc"

you've gotta laugh
(an arc primitive wasn't there for the original logo, nor is it in scratch)
