FLTEACH listserv users have been sharing ideas for practicing possessive pronouns. Here are some of them:
I remember a teacher telling me that when she introduced this subject she would walk around taking things from a student's desk and saying, "It's mine!” And this, of course, led to a discussion of "It's mine,” "It's yours", "It's his/hers.”

To practice these, using realia is great, but perhaps in order to get items that will generate a controlled vocabulary base, you might want to have a list of items that students have studied and give them pictures to cut out of these things, glue to an index card, initial or put first & last name on the back. Each person can do one or two or three or four (m.s., f.s., m.pl., f.pl). Structure the practice with prices on objects---maybe different groups with different currencies on their objects--kids could research what a pair of jeans would cost in Guatemala using quetzales, etc. as a homework done days before. Another group of 4 or so students could have bolivares in Venezuela for their items, and so forth.

I taught them with comparatives and it worked quite well. I told the students they needed to brag about the things they had. I would tell them sentences such as "my house is pretty", and their sentence would be "mine is prettier than yours". We did this for a few minutes until they seemed to grab the concept and then we moved onto the other pronouns. The post-assessment proved this strategy successful.
