I have used this successfully with many previous classes. The past couple of years, however, it has been more difficult to implement because of a lot of comings and goings of students. If you do decide to use it, DEFINITELY have duplicate copies of each student's partner lists that you keep handy. The kids WILL lose them or not have them available when needed. One way that helped to minimize this happening was to have the students staple or glue them to the inside cover of their folders or a notebook. I always make it a rule that they must have a different partner's name for each time slot and that they must have both boys and girls on their lists.
This does take a little bit of class time to set up because it can seem to be confusing at first, but it is well worth it. I found that what worked best for my students was to explain it as clearly as possible at the beginning then to tell them to find a partner for their 1:00 time slot. MAKE SURE THAT EACH CHILD HAS LISTED THEIR PARTNER'S NAME IN THE GIVEN TIME SLOT ON THEIR SHEET AND THAT THEIR NAME IS ON THEIR PARTNER'S SHEET FOR THE SAME TIME SLOT. Don't move on to the next time slot until each step is complete. Trust me, this will save a lot of aggravation!!
This really is a good technique and the kids do seem to enjoy it.
