Description of the Experience
The equation is a mathematical equality, containing one or more variables. Solving the equation consists in finding the values of the variables which fulfills the equation. Variables are also called unknowns and values that fulfill the equation - solutions of the equation. In order to find solutions of the equation is often necessary the expression to be simplified (transformed). This simplification includes changing of sign of the variables when they pass to the other side of the equation. For students to remember that the sign of the variable should be changed when it goes to the other side of the equation I tell the students to imagine that they are themselves. When they are at home they wear certain clothes, but when they go out and want to visit someone or go to a restaurant then they change their clothes. It is the same with the variables which changing their place in the equation need to receive ‘new clothes’ or opposite of their sign.

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.
