Max Maths, Year 4, Learn together, Review of symmetry (1)

In a Year 4 maths lesson, students revisit the concept of symmetry through practical examples. The lesson begins with a scenario where Han, a character from the learning materials, is trying to determine whether various objects around his home are symmetrical. With the assistance of his friends, Han examines each item to see if its two halves are mirror images of each other. For instance, they discover that a jug is symmetrical as its two halves match perfectly when divided along a line of symmetry. Conversely, a key is found to be asymmetrical because its halves do not match when split in the same way.

The lesson continues with the exploration of a nut, which is identified as symmetrical due to its matching halves. The students are then presented with a challenge: to find another line of symmetry on the nut, if one exists. This activity not only reinforces their understanding of symmetry but also encourages them to engage with the concept more deeply by looking for multiple lines of symmetry in a single object. The lesson is interactive and encourages students to apply their knowledge to real-world objects, making the concept of symmetry tangible and relatable.
