To help students become better editors, consider using Jeff Anderson's idea--Invitation to Edit--from Everyday Editing.

Begin by looking at the first sentence, the mentor text, with your student.  What does she notice about it?  She can comment on anything--content, diction, syntax, punctuation, anything.

Once she has studied it and made her observations, cover it and show her the subsequent sentences, one by one, allowing her to point out what is different (i.e. incorrect) about each one.

"In the city of Boston, on a cobblestoned street, a new hat shop was opening for business."                                                            The Hatmaker's Sign by Candace Fleming

To make your own "Invitation," find or write a sentence you want your student to study. Copy and paste it several times, making a change to each one (i.e. delete a comma, misspell a word, insert a homophone, etc.). 

Once your student is comfortable with the process, have her make her own "Invitation" for you or a sibling to edit.  Remind her to put only one error in each sentence, so the activity doesn't become a massive error hunt.
