12 pieces. These bags come with a wealth of arithmetic problems! Included are six arithmetic cubes made of FSC® 100% certified wood, with which countless combinations of arithmetic problems can be rolled - from simple addition and subtraction to more difficult maths problems (e.g. multiplication). All tasks are randomly generated, so the arithmetic remains exciting! By adding or omitting dice, each player determines how difficult the arithmetic problem should be. The 12-piece display belongs to the product group "Educate" and should not be missing in the educational toy assortment and on the sales counter. An ideal take-away item for maths fans or as a small gift for the school cone.
