I taped two file folders to create them last year. I didn't use it the whole year because certain kids would just peek behind the dividers at their classmate's paper. Everytime we did a test, I asked those kids to move their desks away from the rest of the group. I had to keep my eye on them alot last year.
I make "test folders" for my students. I take two file folders, open them and then staple one side of each folder together. This makes a tri-fold folder. The children take them out whenever we have a test that way they have a barrier in front of them and on the sides. They are made very similar to the mini-offices, but without all of the information.
I have always had my students take out 2 pocket folders from their desks to "put up walls" when I need to ensure they are keeping to their own work. This year I am using mini offices. Since I am only putting things on one side of the offices, they can bend them to the empty side when I need them to work alone and not have the mini office resources.
I am glueing two legal size file folders together and then on the first day, letting the kids decorate the outside of them to make it theirs. Then I am going to laminate them so that they stay all year (and they do) I have them store them in their desks so that I don't have to. They also get to take them home at the end of the year!
I found the presentation boards at dollar tree.. so I bought several of them.. I am going to have my husband cut them down for me.. I am thinking I can make 3 privacy boards out of 1 presentation board. If it works it will be a whole lot cheaper then what really good stuff sells them for.
There was a teacher at my old school who used pieces of cardboard scored so that it would be a tri-fold and then put masking tape where it was scored to keep it from tearing all the way. She loved them and used them for all her tests.
I use the presentation boards from Dollar Tree like patschmidt suggested. I cut them in half and made two privacy shields out of one presentation board. They worked great, but they do not fit in the students desk. I just kept them on a shelf and whenver we needed them I would have someone pass them out or call groups to go get them. Way cheaper than Really Good Stuff but the same concept !
