Infant Teachers try to ensure that all young people in their classrooms have access to the necessary tools of trade. In some classrooms books, pencils, rubbers, rulers, sharpeners, etc. are kept in the students' desks. In other classrooms they are kept on, or near, the teacher's desk, or at some other location in the room. Crayons, paints, paper, scissors, etc. all have special places. Where these are, and the rules for use of each item, are quickly learnt by children when they become members of the class. It is unusual for any of these items to be difficult to find or out of reach of the children. But some children have difficulty in acquiring and keeping the items they need.
