persuasive writing

My elder dd needs to learn persuasive writing for her English curriculum. While all she can do is persuade me for everything and present her arguments in every possible manner, she cannot seem to write about it. Not because she cannot but only because she cannot concentrate on the work on hand for more than 2 minutes.
Lack of concentration and distraction from work being done is affecting her ability to do work efficiently.
It concerns me.
For now.
