Presentation: individual or in couples
Material: a cardboard lid – coloured paper, bristol type – cardboard rolls
Each child prepares 4-5 small rectangles of white paper and colours them with 4-5 different colours (or cuts out coloured paper ready to use). Then the children paste them on the cardboard rolls. After that each child pastes the rolls, with their colour clearly visible, inside a shoebox. He/she puts the ball in the box and follows a code being established by a sequence of coloured papers, which each child can place in front of him/her, of the same colours used for the rolls.
