Dr.Scheme what I learned:

When I first did Dr.Scheme, it was a bit complicated, but I got the hang of it after a while. I learned how to draw circles/rectangles using Dr.Scheme commands. For example I learned that the part of the code: "30 30) green)" is the length and width and the color of the shape you’re executing. Also, "(make pos’n" is the position of the shape or where in the grid it’s going to be located.
