Dick-System 40 giant stock cubes

For an illustrative mathematics lesson. The plug-in cubes have a highly challenging character because they can be used in so many different ways. The cubes have been highly regarded in primary schools for many years and are used for descriptive recording of quantities, number spaces, comparing, counting, calculating, laying and for training the spatial imagination. The small cubes can be plugged together in any direction and on all sides. What can you work with cubes? Counting, calculating, building and measuring, recording quantities, building in the plane, laying shapes, bigger, smaller, same: different heights of cube towers illustrate the mathematical signs, adding, subtracting, spatial construction and building, decimal system of ten transition, logical rows. Details: side length: 3.4 cm, 40 pieces.
