Introduction

The cube consists of 8 small cubes and prisms, that can be used to build a big cube. The picture on the cover as well as the rule that only the same coloured surfaces must touch helps to check for errors. A beautiful presentation and more information can be found in Linda's Montessori Shop or on YouTube.
