I number each child according to the roll. The children learn this number and write it on all work that is handed to me. In addition, every student has a lever arch folder with his or her number on the front. As we complete worksheets, they are filed in the folder under the appropriate subject. At the end of the year, the sheets are bound together to form a record of the school year, together with exercise books that the students take home to share. This is our way of getting over the scrunched photocopy at the bottom of the bag!
