I loved this idea.  Once I figured it out, (and it it took me way too long to figure it out) I did it EVERY year at the end of the year!  I am not sure about other schools’s end of year routines, but in the schools I worked at we had to clean our rooms, pack up most of our belongings, cover them with paper, and move them so the custodians could clean the carpets and the walls.  It was tons of work.  Not just to pack up, but also to UNPACK in July.
This was  my class the last year I taught.  No fun. All the stuff on the table needed to be packed up to go home.
Luckily, I came up with the “Next Year” box.
It saved my tush every year when I was unpacking for the new school year.  In the “Next Year” box I kept all the materials I wanted to be able to access quickly and prepare for the next school year.
I don’t know about you, but waiting for copy paper was a pain.  Not only were the copiers crazy busy (and always jammed) after people got their paper, but you had to wait to get it. I always kept a ream or two in the “Next Year” box so I could get a jump on copies.
I have already written about using cheap, Wal-Mart sheets to cover my bulletin boards. I go ahead and pick those up in May and store them in the box.  I also try to run to the teacher store and pick up my “stuff” for next year to avoid the rush (and out of stock frustrations). I store all this in the box.
I also try to make all my copies for pre-registration in August (we called ours Sneak a Peek) so I didn’t have the fight the copy crowd. It took me forever to set up my room,so every little bit helped.
I have several themes for back to school forms.  I used the owl theme.  You can pick them up for only $2 in my TpT shop.
Do you have a “Next year” box?  What do you keep in yours?
