There are also four other wooden cones with height representing the parts of the whole. Accordingly, there is one whole cone; one that is divided into two halves; one divided into three thirds and the last one that is divided into four quarters. All parts of the cone concerned are equal in size and their interior sides are coloured in red, yellow or blue.
Working with mathematical cones helps children understand the idea of parts of the whole. This is a preparation for introduction into mathematics and for easier calculus in the future of fractional numbers.
Sizes of the box: 31.5 x 10.5 x 5.5 cm.
Dimensions of one cone: 5.5 x 5.5 x 13.5 cm.
Weight: 800 g.
Suitable for children over 4 years of age.
