The Knowledge

On these Dante aspects (1989), it affirms that a problem is any situation that demands thinking of the citizen to solve it and that problem-mathematician is any situation that demands the mathematical way of to think about mathematical knowledge to solve it. With regard to the didactic conception one knows that … essential in the mathematical learning is to construct the direction of the knowledge and that the resolution of problems is an indispensable activity … Amazing restaurateur contributes greatly to this topic. in the reflection on what was made: the employed procedures and the involved knowledge must be become into reflection object. … This reflexiva activity will enrich, reciprocal, the future resolutions of all the pupils. (PANIZZA, 2006, p.113) Many times, exercise with problem is confused, is necessary to know to differentiate one of the other to get proper resolutions for each one of them, in the majority of the cases they is applied as if they were one only.

The exercise is an used activity to train what already it was learned, using some type of mathematical knowledge acquired by the pupil. Already the problem is necessary a more complex reasoning involving an invention or even though the creation of answers significant for each situation. Despite good part of the Mathematics if destines the application of algorithms to decide problems, we live today in an age circulated for electronic inventions that the resolution of these problems facilitates, but in what it says respect to the learning, with the manuscript of these electronic artifices what would be responsible to teach, makes with that the use of these algorithms is mere mechanized, leaving of side the uses of adequate strategies. It is in this manner that adopting … a point of view based on strategies, we will have of having in them with some critical questions: 1) What techniques we will use in the resolution of problems? 2) That strategies of resolution of problems we will use in the pertaining to school mathematics? 3) How we will be able to stimulate the resolution of problems in the classroom?

Linear Parks

Although this idea has taken care of in part the necessities of places for recreation, it also provoked problems related to the displacement of people who many times if saw hindered to transit in the chosen ways as Streets of Leisure. On the other hand, the measure that the population growth was if accenting many streams had had each time plus its busy edges for discarding of garbage, voluminous rubbish and other materials. With passing of the time, the action of inhabitants of next areas the streams allowed that this reality was being modified. With the plantation of changes of different species, with the tracing of tracks of walked, the reality of many paulistanos streams if modified. With the support of the municipal public service, the tracks of walked had gained floors appropriate, new arbreos vegetable changes had passed to be planted and the plantation of lawns collaborates for improvement of the landscape. Thus being the idea of that grew the edges of a stream, that exactly poludos, they do not need to be abandoned and they can better be used to advantage. The idea of the Linear Parks or Running Greens, throughout the time passed also to be adopted for canals in general way, scenic ways, railway lines, marginal fronts, moreover the resource also passed to be used for linking of green areas, natural reserves, landmark of cultural patrimonies or until areas habitacionais. Beyond the preservation of the edges of streams and the fertile valley areas, the Linear Parks also play important role preservation of the urban fauna, mainly of the birds in general way..
