Length and Perimeter - Comparing length​ - Planning

In a Year 3 mathematics lesson on measurement, focusing on length and height, students embark on learning how to compare different lengths. The lesson utilises a variety of resources such as physical objects, worksheets, and a presentation to facilitate learning. Key vocabulary terms such as metre, centimetre, and comparative phrases like 'longer than', 'shorter than', and 'equal to', are introduced. These terms are crucial for understanding how to articulate and quantify differences in length. Pupils are encouraged to visit a supplementary website for vocabulary cards and definitions to strengthen their understanding.

The lesson begins with a recap of previous learning, setting the stage for students to apply their knowledge of centimetres and metres. They engage in activities that involve using the correct vocabulary to compare lengths and matching words with the comparison symbols: less than (<), greater than (>), and equals (=). Practical tasks include measuring objects within the classroom and using these symbols to compare their lengths. The lesson also incorporates reasoning exercises, such as solving problems that involve doubling lengths and using the newly learned vocabulary and symbols to articulate these comparisons. Throughout the lesson, key questions prompt students to think critically about measurement and comparison, while common misconceptions are addressed to ensure a robust understanding of the concepts. The lesson concludes with a reflective 'Give me five' activity, where students assess what they've learned and identify areas for further practice, with differentiated outcomes for varying levels of understanding.
