An intellectual training block set is provided to enable a child to naturally learn spatial concepts while playing games by acquiring areas and volumes of various shapes made by using the blocks. An intellectual training block set includes first and second block slices(S1,S2) and a scale part group(S3). Numbers are displayed on design surfaces of the block slices in the first block slice group. A thickness of the block slice is set to the same value in a direction normal to the design surface. No number is displayed on block slices(11-14) in the second block slice group. The block slices are set to the same thickness. The block slices are formed in a spherical shape. |
