We believe it is not possible to spend an ordinary day without using Math. We even need Math in order to spend a simple day. The aim is to increase levels of achievement and interest in science, technology, and mathematics, with the priority of reinforcing the development of key competences. This project is a follow up to the Active, Attractive and interactive EU Mathematics project. Each school will be able to continue the celebration of maths days, practical works with the following generations of students. And of course, discover something new.
