Background

Mathematical thinking is the ability of a person to think in what is commonly referred to as mathematical thinking, i.e., the ability to think about and solve problems from a mathematical standpoint. Such as translation and classification, from general to special, special to general, idea of function/mapping, etc. Generally, people with strong mathematical abilities basically express two abilities, namely associative ability and digital sensitivity. The former can tie together two seemingly unrelated problems, which in turn is most compromised by construction ability; the latter is the so-called geek of most exposures, such as what Nash, and of course a combination of both capabilities.

The training of mathematical thinking is that the training of present teaching is very attentive, but present student when study, most of acquireing all are the teaching of the hard back of the body formula of remembering by death, and this is in the past for the student can only remember knowledge, and can not open student's innovative thinking, and is unfavorable to cultivateing child, so needs a mathematical teaching aid that is used for mathematical thinking training.
