Description of the educational product
This model is addressed to young secondary school students.
This model tries to show that every position of one side of the see-saw has the opposite side of the see-saw at the other end. And the center point of the pivot, the fulcrum, is always at the same distance from both endings
Similarly, every number has an opposite that is same length from the 0 number, so that the 0 stays in the middle

Really a great idea for a model!! it's really a model form very easy to understand. I am sure I will use in my lessons because I think that my students will understand it very well.

I am a teacher of mathematics in primary school, but at the same time I conduct individual classes with students from junior high school. I like this model. It could be helpful to present the notion of the opposite eof a number in playful way.

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.
