Length and Perimeter - Measure length - Planning

The Year 3 spring term lesson on 'Measure Length' is part of a broader unit on Length and Perimeter, where students are expected to learn how to measure, compare, add, and subtract various units such as lengths (in metres, centimetres, and millimetres), mass, and volume. This particular lesson is designed to introduce children to millimetres, reinforcing their understanding of centimetres and metres. A variety of measuring tools are provided, including rulers, tape measures, metre sticks, and trundle wheels, and the children are encouraged to select the most appropriate tool for the task at hand. They learn the importance of starting measurements from the zero mark on the tool and how to record their findings accurately. The lesson includes practical activities where students measure lines and objects, exploring the conversion between different units of measure and discussing when to use each one.

During the lesson, students engage in partner discussions to understand which measuring tool and unit of measurement would be best for different objects, such as an exercise book or the playground. They are introduced to the concept that there are 10 millimetres in a centimetre and are asked to apply this knowledge in practical measuring tasks. To ensure understanding and accuracy, the lesson includes activities aimed at addressing common misconceptions, such as not aligning the object correctly at the zero mark on a ruler. The lesson concludes with independent work on differentiated worksheets, and a reflective 'Give me five' activity where students consider what they have learned, the skills they have used, and what they found challenging, ensuring the key concepts are remembered for future application. Different levels of achievement are outlined, from 'Working towards' to 'Working at Greater Depth', with tasks designed to challenge students at their respective levels of understanding.
