Be on the ground when a new game is launched. Study the possibilities
for unfair playing (silently, of course), and make every effort to
establish rules that will be just to all.
Do not stop at this point, however. Play with the children frequently
enough to learn at first hand whether strict rules of honor are being
observed or whether the leaders are taking unfair advantage wherever
opportunity offers.
Say to Reginald and Carl, “If one of the boys on the other side had made
that play would you have wished to count it?”
If the boys can not be converted to a desire for strictly honest play,
then see to it that the ringleader gets no advantage from his
trickiness. Say, “We’ll have to throw out this whole game because it
wasn’t played quite fairly. Tomorrow we’ll have another game to take the
place of this one.”
