Converting Units - Millimetres and Millilitres - Presentation

In a comprehensive set of teaching slides, students are introduced to the concept of converting units, specifically focusing on millimetres to metres and millilitres to litres. The lesson prompts students to consider everyday objects that might be measured in these units and to discuss the meaning of the prefix 'milli'. This foundational understanding is crucial as they tackle a variety of activities designed to solidify their knowledge of unit conversion. The exercises include straightforward conversions, such as 1,000 millimetres equalling 1 metre and 1,000 millilitres equalling 1 litre, as well as more complex problems requiring students to convert larger quantities and to work out the conversions in reverse.

Further activities challenge students to compare measurements using mathematical symbols for greater than, less than, or equal to, which helps to contextualise the size differences between units. For example, students are asked whether it would be appropriate to measure height in millimetres, encouraging them to think about the practical applications of different units of measurement. Real-life scenarios involving the sale of cola in millilitres and the purchase of ribbon in millimetres bring a practical element to the lesson, requiring students to apply their conversion knowledge to reasoning tasks. The lesson culminates with independent work, where students complete missing measurements, determine the truth of statements regarding conversions, and use stem sentences to convert between units, reinforcing their understanding of 'milli' and its applications in everyday measurements.
