In my son's class, the "Friday folders" (which are really envelops) go home without the kids going through them. It contains all the work being sent back, all the notices from school, etc. Lots of papers! I don't see any problem with putting invitations in select folders like this. Notices to parents that may only go to specific students also go in there (i.e. confrences, testing results, etc.).
Our school is different from most on this board as we generally drop the kids off and hang around, so I do see most parents at school and know them. It was easy for me to get the emails of the kids my son wanted to invite. However, I don't see anything wrong with sending invites home with a few kids discreetly.
Would people that have a problem with this also have a problem with sending a note asking for a playdate?
