Magicians, as well children, have forever asked a person to consider
a number either, on a card or a number of objects. They then manipulate
the situation and are able to produce unnatural results (or at least
unatural to our mathmatical reasoning). Try the activities,
some are old, some are new, most are borrowed and links are blue.
All are grouped to fit the
NCTM Math Standards.
These activites are selected to interest all levels of
users.
