Description of the Experience
In acting with roots students often get confused on how to perform actions on the numbers under the root.

I explain them that the actions should be carried out with the equal numbers, e.g. first the one without hats and then the other with hats: .

We believe this experience relevant to explain the problem because it is very simple to implement in the classroom. It is easy to explain the resolution of roots. Students find it easier to understand the method using examples because mathematical logic at times find it very complicated. Related to this same theme, the same teacher speaks in another example related to the roots, which is complementary to this example.


Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
