Take a look around your home and garden and it’s clear to see – whether it’s a beautiful butterfly, or a tiled pattern in your bathroom, the mathematical principle of symmetry is evident in everyday life. It’s no surprise, then, that it’s an important concept to teach starting from an early age.Reflectional symmetry（或线对称性）对于孩子来说可能是一个棘手的概念 - 但是有了正确的活动，您的学生将立即钉住它。
