From Slideshare.net: His hers yours mine

I'm linking to this in an effort to keep track of and index useful teaching material.  The above link is useful for teaching possessive pronouns.

I came upon it as a result of a question a colleague had.  He was teaching possessive pronouns in English World 3 Unit 12, and he noticed that the textbook taught the form as "This hat is mine" but the test at our school used the form "Whose hat is it?  It is mine."  So after searching on the web, I found this slideshow that could be used for this grammar point.
