Numbers of the montessori method?

Montessori Numbers is a set of five mathematical activities that follow the Montessori method. The application includes counting, block manipulation, stacking, number cards and number matching. The first step in introducing the concept of counting and numbers is one-to-one correspondence. One-to-one correspondence is the ability to count while pointing to one object at a time.

It's assigning a number to one and only one object at a time. It's not about counting by heart or memorizing, but about really understanding the meaning of numbers. Memorizing how to count to ten doesn't help the child unless he knows what those numbers represent. While there are schools that educate their students using this method, parents who study at home can also use the same strategies and materials to implement the Montessori method at home.
