Where does Turtle Art come into this? Turtle art has variables, of course, which it calls boxes to reduce confusion, and we can name one "apples" and one "oranges", and add them as vectors in a two-dimensional space, the TA on-screen workspace. I don't want to take the trouble to make the turtle draw apples and oranges, so I will use colored dots instead, orange and red. (Feel free to improve on my work, as real mathematicians, artists, and so on do.) Here you go.

The idea of the box in Turtle Art is that we have a box with a name on it, and we can put a number or a bit of text inside to take out or make copies of later. This model, like the model of pronouns, provides an easy way for children to avoid being confused by adults talking in nonsensical shorthand that would require an explanation that most adults do not know how to give.
