Description of the Experience
The thematic unit of Stereometry does not belong to the favorites thematic units in mathematics. Students have some knowledge of of it already from their elementary school studies. I use this fact to ensure they get familiar with the mathematical bodies from a different perspective as well. Most of them think that cube, cuboid, cylinder, cone and sphere ... exist only in mathematics. I try the students to befriend the bodies by looking around them and exploring their different specimen forms. Then we discuss how their day goes beginning from the morning of the day and where everywhere they can come into a contact with the bodies. Then the students divide themselves into groups that are formed by 4 students and have 20 minutes to write out as many things, objects, specimen of normal life in the shapes of cube, cuboid, cylinder, pyramid, cone and sphere. Of course, they must be identified correctly into the individual categories of the bodies. Then I collect these papers. After that one student comes from each group and reads out aloud the written answers of his or her group. Other students in the class count the number of correctly identified specimens. The winning group is rewarded by a grade. I have good experience in preparing this task as students use their fantasies. At the end they are often surprised by the volume of objects they discovered related to mathematics. Plus is also the fact, there are no examples to calculate.
The last part of the lesson is designed to set the homework. This time I divide the students into pairs. Each pair has to prepare a PowerPoint presentation on the bodies around us. Each presentation focuses on a different theme. E.g. bodies in sport, household, food, construction. Chefs look for bodies in their industry, waiters in theirs. One pair will prepare a presentation from a mathematical point of view, where there will be geometric objects in free parallel projection and the formulas for calculating their volume and surface areas. The presentation has a minimum of 6 slides dedicated to 6 geometric dimensional structures in which there are images used as examples of the subject. Each pair presents their presentation during the next class by demonstrating the topic in front of the class. Sometimes two lessons are needed for this task. At the same time I guide them to think of and eventually invent examples of what situations can be adapted for counting. Then the students are ready to compute examples. These two activities really help them get into the task of calculating the spatial volume and surface areas of geometric figures and in particular, the practical application that is visible in the examples.

Author's experience is significant from the point of view of motivation and linking the mathematics and acquired pupils’ competences from mathematics with a normal life of the pupils. Searching for "things around us" from the mathematics’ view clarifies the process of formation of concepts, definitions and sentences in mathematics to student. This will allow them to understand that the formula originated as dependencies between different variables directly from everyday life to solve practical problems.
• Does this experience explain the causes of students’ low motivation to learn science subjects?
This experience clearly defines why students do not have relation to that subject matter – they do not see the practical use and the roots of developing the particular relations.
• Does this experience offer possible solution to overcome this low motivation?
In my opinion, yes, the author activates pupils in a way that allows them to see mathematical objects in everyday life.
• Do you have a similar experience?
Yes, I have a similar experience; students in groups were creating parts of the town from mathematical objects (they planned parks, roads, residential areas, shopping centers from bodies of various shapes, which they had created themselves).


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.
