Description: Sal answers the question by drawing a square and thinking about the relationship between side length and perimeter. And what I want to think about here is whether the perimeter of the square is proportional to the length of a side of the square. So there you have that, we have that, and we'll make three columns and on the first column we're going to think about the Side length. And in the next column I want to think about the Perimeter.*Teacher Advisor is 100% free.
