Converting Units - Imperial Units - Starter

In a mathematics lesson aimed at Year 5 students during the Summer Term, the focus is on developing fluency with numbers and understanding imperial units of measurement. The lesson begins with a 'Fluent in Four' revision exercise where students tackle arithmetic problems such as subtracting large numbers, for example, calculating the difference between 2,684 and 767. The exercises encourage mental arithmetic and place value understanding, as students work through hundreds, tens, and ones to find the answers.

The lesson also introduces students to imperial units, specifically inches, and their approximate conversions to centimetres. Students are given the conversions of 1 inch to approximately 2.5 cm and 2 inches to approximately 5 cm. They are then challenged with questions that require them to apply this knowledge, such as converting inches to centimetres and metres. Additionally, the lesson includes a task where students must subtract mixed numbers and shade a table to visualise the process. This multifaceted approach helps reinforce their understanding of both arithmetic and measurement, ensuring they grasp the practical applications of these mathematical concepts.
