Description of the Experience
While performing acts with roots students often get confused on what to do with the numbers under the root. For example when 3 and 5, placed under square root, should be collected, quite often students decide to collect the numbers under the root and then to perform radical of the sum (8). In order to explain that it could not be done such collecting of numbers nevertheless that they both are under square root I give them the example with collecting mechanically a pear and an apple in one fruit. They answer this is impossible because they are different. I reply that it is the same with the numbers under the square root – they are different. That’s how they remember that they can’t mechanically act with roots.

We believe this experience is relevant to explain this problem. Although the example of pears and apples seem simple, actually meets the desired goal that is not to confuse the operands and operations to be performed in the roots.
Students find it easier to understand the method using examples because mathematical logic at times find it very complicated. Particularly, I had not used this simile in my classes, but I think it is a good example and probably i will use it if there is occasion.


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.
