This is a blog created to the Etwinning Project Fun and Math. A project directed to mathematics, focused on funny and stimulating activities for children, enabling them to gain some interest and pleasure for this subject, but also explore their logical-mathematical thinking abilities and skills. With this project we intend to share challenges, problems, online games and tasks that allow children to improve their performance in Math.
