This is pretty self-explanatory, but in case you are a person that likes directions……..
What you need:
9 1/2″ by 13″ piece of cardboard (from a box), 2 clips
I cut the cardboard to size and use the clips to hold the paper onto the board. There is room under the clip to hold a pencil. The park district I used to work for used pizza boxes; they would also tape a piece of of yarn to the board to tie on a pencil. The yarn really helped keep the little ones from losing their pencils.
