We would like to establish an exposition of art pieces that show the relation between art and mathematics - online and in the twinspace. Students from 10 years to 15 years will participate. We will start on the one hand from art,then students discover the maths behind. On the other hand students create art work creatively by using math /geometry. Teachers of the project will provide a lot of different opportunities for collaboration between students of different countries and for teachers as well. Art work will be created by using paper, pencils and cardboard but also by using software.
