The Combination Of Number And Graph In Mathematics Teaching

As is known to all, Mathematics is the study of quantitative relation and spatial form, Simple said isthe science of Numbers and forms. Number is abstract, and shape is intuitive, two research object ismatched Each other. In nearly three years of teaching practice, I found the question, Many algebraproblems directly calculate the computational cost is too big, even do not know how to start, but if afterconverted into visual graphics can easily be resolved by graphic nature; And some graphics because someauxiliary line not to come out, also can’t study, but often through methods such as coordinate system intoalgebraic problems after it is easy to get the result. This method of thinking is a kind of commonly used onour mathematics thought several form combining ideas one by one. Contact number form is good bondbetween Numbers and forms, has a very important role in solving mathematical problems. For now,however, most of the students just know this kind of thought, concrete application is not aware of or do notknow how to start. In order to solve this problem, combining my own three years teaching is summarized,and the experiences of people in front of the reference for related literature, on the basis of logarithmicform combined with the concrete application of do some simple introduction.In this paper, the process of writing I mainly adopts literature research, mainly from the followingseveral aspects: First simply introduce problems put forward the background and significance, and then thedefinition of related concepts specific to elaborate, then mainly introduces several form combining the roleof thinking in the teaching, Mainly two ideas: one is " A geometric solution for algebra The problem ", oneis " Use algebraic method to solve geometric problems ", through specific examples to further explain again.Finally introduce number form in combination with the way of thinking, principles, limitations, etc.
