Children learn to count from 1 to 10 in a playful way with these stacking blocks. The cubes are decorated with our Little Goose and his friends that live around a pond in the country side. Either stack them vertically to make a tall tower or arrange them horizontally in a parade to learn about sizes. Place the little cubes inside the larger ones for easy storage. The cubes are made of sturdy cardboard and are resistant to bumps. The smallest block is 5 cm and the largest block is 14 cm.
