A kaleidocycle is presented in which the entire periodic table has been collected. In this three-dimensional figure are the elements organized in four blocks according to their final electronic structure. It is intended that students with this playful figure actively participate in classes by rotating their kaleidocycle looking for the groups or elements that are being studied. The entire periodic table fits in one palm of their hands. It is also a didactic device because students only focus their attention on one block or group of elements from the entire Periodic Table. It can be achieved a more entertaining, motivating and exciting learning about the subject of the Periodic Table.
