The set includes 100 ribbed coloured sticks + a bag. Stick length: 10 cm (4") and diameter: 8 mm (0.3"). In this set, the sticks are sorted in rainbow colours, in 10 bundles. The application of this set is very versatile. For young children, in order to develop systematization skills, we suggest sorting them by colour. Older children can create different geometric shapes, letters and numbers. You can indulge in various expressions of fantasy and create your own ornaments and images. But the main task of these sticks is to easily and understandably enter the world of mathematics. By working with them in practice, it is possible to clearly introduce amounts such as one, ten, hundred, more - less, the composition of numbers. This set will definitely be useful in understanding math equations like "addition and subtraction".
