Converting Units - Imperial Units - Worksheet

The 'Imperial Units' worksheet is an educational resource aimed at Year 5 students, helping them to understand and use approximate equivalences between metric and common imperial units such as inches, pounds, and pints. In this lesson, children are introduced to these traditional units of measurement, with the National Curriculum objective of grasping the approximate equivalences between them. To facilitate practical understanding, the lesson utilises classroom objects like rulers and pint bottles. Key vocabulary includes terms like 'approximation', 'equivalence', and 'imperial units'. Students learn that 1 kilogram is roughly equivalent to 2.2 pounds, aiding their understanding of the conversions.

Students are encouraged to think critically through key questions about the usage of imperial units and the nature of approximation. They are provided with differentiated worksheets and teaching slides to support their learning. The worksheets involve converting measurements such as inches to centimetres, pounds to kilograms, and pints to millilitres and litres, using bar models to visualise the conversions. For example, 1 inch is approximately 2.5 cm, 1 kg is about 2 lbs, and 1 pint is close to 568 ml. As they progress, students will also tackle reasoning and problem-solving questions involving imperial units, such as calculating the total litres of milk delivered weekly or comparing the birth weights of babies given in different units.
