Copy work as a creative writing tool:
Copy work is: You take a piece of great writing, copy it down, with a pen (or type it). Copying down what others have written helps develop the connection between you, and your writing habits. The main reason to do copy writing is to simply become a better writer.
Copy work as an educational tool: Copy work is a good practice for handwriting. It’s also important for kids to be familiar with proper spelling, grammar, and a higher level of vocabulary than they can produce on their own.
