从上幼儿园开始我们就开始认识正方体,它是几何图形对称完美的化身.从小学、中学一路过来我们对它的认识也越来越深,真可以说是“熟透了”.但就象小时候玩一种叫“魔方”的玩具,看似简单,却越玩越有劲,越品越有味.在立体几何的教学中本人就体验到正方体就象“魔方”一样值得玩味. From the beginning of kindergarten, we began to understand the cube, which is the perfect embodiment of the geometric symmetry. From the elementary school, middle school all the way to our understanding of it is also getting deeper and deeper, really can be said to be “complete”. But As a child playing a toy called “Magic Cube”, seemingly simple, but the more the more vigorous play, the more tasteful the more goods. In the teaching of three-dimensional geometry, I would like to experience the cube is just like the “Magic Cube” Playful.
