Sorting game by weights, colors and geometric shapes. There are 3 groups of pieces, all with the same size. Each group is made up of a circle, a triangle and a square with the same weights, 40g, 80g and 160g per piece. There are 6 different colors randomly printed on the front and back of each piece. 12 tokens with colors, weights and geometric shape attributes, and their corresponding "negation cross" on the back. This game allows many sorting combinations by classifying the pieces according to: the weight, the color or the geometric shape, depending on the proposed attributes.
