When your child typing a copy of something, here is a simple way to prop up the paper to make it easier for your child to see.
When typing the first half of the paper, fold the paper in half with the text facing forward, and slip the bottom half of the paper under the keyboard as shown in the picture above. 
When typing the second half re-fold the paper in the opposite direction, then prop it up behind the keyboard like a tent, as shown in the picture above.
