Position and Direction - Reflection - Presentation

In a lesson centred around the mathematical concept of reflection within the topic of position and direction, students are introduced to the term 'reflect' and are encouraged to discuss its meaning and where they have previously encountered the word. The lesson aims to teach students how to reflect shapes across a mirror line. They begin by examining various images to determine which have been reflected across the mirror line. This initial activity sets the foundation for understanding how reflection alters the positioning of a shape while maintaining its dimensions.

Subsequent activities involve more hands-on practice with reflection. Students are tasked with reflecting coordinates and various shapes across a mirror line, reinforcing the idea that while the position of the shape changes, its size and dimensions remain constant. The lesson also incorporates reasoning exercises where students are prompted to challenge statements such as "When you reflect a shape, its dimensions change," encouraging critical thinking and a deeper understanding of the concept. Independent work further solidifies learning, as students tick or cross diagrams to indicate correct reflections, and they contemplate the effects of reflection on the properties of shapes. Discussion points are provided to stimulate conversation about the nature of reflection and its impact on coordinates and shapes when applied to different mirror lines.
