又到了小朋友喜欢的数学思维训练课了。老师打开电脑,展示了一幅图(如右图),并指着图对大家说:“每个骰子的六个面上分别画着1~6个点,每相对两个面上的点数之和都是7。将4个同样的骰子摆成一竖排,压住的面共有7个。大家猜一猜,这7个看不见的面上的点数之和是多少?” Also went to children’s favorite mathematical thinking training class. The teacher opened the computer and showed a picture (pictured to the right), pointing to the picture and saying to everyone: “Each dice has six to four points painted on each side, And the sum is 7. Put the same four dice in a vertical row, the pressure to suppress a total of 7. We guess, the seven invisible points on the surface of the sum of what is the sum? ”
