Abstract
In this paper, we developed tool to learn the calculation process of HOSVD. This tool uses newly created puzzle using some of MacMahon’s coloured cubes. The puzzle is represented as the 2D map using the matrix unfolding required to calculate HOSVD. In order to investigate the difficulty level of the puzzle and the visibility of its map representation, the teaching tool is tried by our students and others at the Campus Open Day of our college. As a result, it was confirmed that most users could understand the map and that the puzzle was rather easy to solve. Therefore, it was thought that the users seemed to understand the concept of the matrix unfolding roughly.
