No shopping list or piece of paper is safe in our house these days. As Popps learns to write a new letter each week in the class room she is also changing her writing style and playing with the way her letters look. It is important to her to get the letters correct and to look like the teacher wants them to look and she practices on anything that doesn't move. And sometimes on things that do (it was only chalk, dogs don't mind having their names written on them).
I stumbled across the rED Writing App and it has saved a handful of work documents from being drawn on. Not many, but it's a start.
