What you think might be "chicken scratch" or scribbles is actually the beginning to writing.
In this article in the Educators Voice journal:
The process of drawing and writing in a series stimulates children to make connections between letters,words and visual symbols. It sparks their interest in acquiring the skills to communicate their ideas through images and words.
So while you might just think its a waste of paper, its actually a stepping stone to their adventures in reading and writing!
Why not try and see?
Have a great safe day everyone. Try and enjoy the snow!
