Without a doubt, seeing children enthusiastic about learning and creating is the best way to celebrate. And you do not need a specific day for that, but whenever possible.
I invite you to watch the video of the didactic workshop- learn with Almada Negreiros, held in June at the BE Patrício Prazeres school in Lisbon. On that day, a group of students aged between 10 and 11, inspired by the colours and techniques used by Almada Negreiros, gave free rein to their imagination.
