Large ball of string
Sit the children in a circle and emphasize that they must remain in their seats or seated on ground (for safety reasons).
The game starts by a child or the teacher saying the name of someone else in the circle and holding on to the end of the string, while throwing the ball to the person they named.
The receiver calls out the name of another child, and keeps hold of his or her end of the string while throwing the ball of string on to the named child.
As this continues a web begins to be formed by the criss crossing string.
The fun really starts when the group has to undo the web by calling names and throwing the ball of string which is rewound by the receiver before sending it on.
