In today’s Year 3 maths lesson, students revisited the concepts of symmetry by sorting shapes into symmetrical and asymmetrical categories. They learned that a shape is symmetrical if it can be divided into two identical halves, while an asymmetrical shape cannot, and the lesson also emphasized the importance of lines of symmetry in various objects. Key vocabulary included symmetry, symmetrical, and lines of symmetry, and resources like cutout shapes and mirrors were used to enhance understanding.
