Σελίδα 31 - Number is not (psychologically) got from things, it is put into them.

Σελίδα 124 - Mental arithmetic, systematically taught from a rationally prepared text-book, is the life and soul of rational method. There is constant adaptation to the normal mental action of the child.

Σελίδα 31 - It is then almost equally absurd to attempt to teach numerical ideas and process without things, and to teach them simply by things. Numerical ideas can be normally acquired, and numerical operations fully mastered only by arrangements of things— that is, by certain acts...
Σελίδα 39 - Grube method (with many methods in all but name identical with the Grube) says that some one thing is the natural beginning from which we proceed to two things, then to three things, and so .on. Two, three, etc., being fixed, it becomes necessary to master each before going on to the next. Unless four is exhaustively mastered, five cannot be understood.
