In the first days of the 2nd term we were discusing about the extension, the population, the DGP and the energy of the countries of the world: our class was the world, the tables and chairs were the continents, we were the population, the money that each continent have were fotocopies of dolars $ and the energy that each continet consume were biscuits that we ate later!!!! ;P

Here you have a table wich shows all the information:

%	Extension	Population	DGP	Energy
Asia	30	60	38	8
Africa	20	14,5	4	3
North- america	16	8	24	50
South-America	12	6	7	10
Europa	7	11	26	27
