Children Who Habitually Cannot Share
Occasionally there are children who head fort he same material every day and refuse ever to give it up. Several approaches may be appropriate in this situation.
Consider why the child must possess this item. Children who come from large families or impoverished homes may feel a strong need to claim something as their own. Perhaps it is an object or material the child never has a chance to use outside of the classroom. A duplicate or equally attractive item can be provided for other children to use. It is important not to label this child as a "problem," but to try to understand the behavior and the child's need to possess the object.
Establish a system for equitable use of an item. Use a clock or timer to show children they can use the favored item for five minutes. A child might be allowed to ride the popular tricycle four times around the concrete track and then give it to the next person. If a system such as this is in place from the beginning, no child feels singled out.
