Mathematics
Montessori materials represent all types of quantities. In the Montessori
environment, children not only see the symbols 1;10;100;1000; or (?), but
they can also hold each of the corresponding quantities in their hands.
Later, by combining various pieces of Montessori materials, they can
demonstrate to themselves the basic operation of arithmetic and go from
the concrete to the abstract. These activities give them the satisfaction of
learning by discovery, rather than being told. Eventually, they develop an
enthusiasm for the world of numbers.
