Mobile phones should be banned at school
Everybody says that mobile phones should be banned at school because they usually interrupt the class. However, I think that mobile phones are necessary because it is possible you need them when there is an emergency.
On the one hand there are some arguments to ban mobile phones at school. They annoy a lot if they ring in class. Students sometimes pay more attention to the mobiles than to the teacher. This is really the reason that teachers give, but students nowadays don’t admit any reason because they want their mobile phones to listen to music at the end of the class.

4.1 The stages of learning as Dienes
The learning process is a process based on abstraction, generalization and communication. This process of abstraction is to accurately analyze and Dienes identifies six different stages in it:
Stage 1: introduces the individual in the middle => Game Free
2nd stage: review, manipulate, get rules => Structured Games
3rd stage: becoming aware of the common structure to games made
4th stage: representation of the common structure graphically or schematically => Stage representative
5th stage study of the properties of abstract structure, which implies the need to invent a language => Stage symbolic
6th stage: Construction of axioms and theorems => formal Stage
Her pedagogical approach

System Types
The systems of equations can be
classified by the number of solutions that can arise. According to that case may have the following cases:
· Incompatible system if it has no solution.
· Compatible system if you have any solution in this case can also distinguish between:
or compatible system determined when it has a finite number of solutions.
indeterminate
or compatible system when it admits an infinite set of solutions.

 in-adverbials + simple past express the  ‘size’ of a [+durative] [+telic] eventuality, and as a result: With states they are usually anomalous because states are [–telic].  // With  activities they are usually anomalous because activities are [–telic] // With  accomplishments, which  are  [+durative]  [+telic],  they are  perfectly natural  and express duration of the event // With  achievements, which are [–durative], they can only express the time elapsed before the  event (onset reading).
