Multiplication and Division (1) - Multiples of 10, 100 and 1,000 - Planning

In the third week of the Autumn term, Year 5 students delve into the topic of Multiplication and Division, focusing on multiples of 10, 100, and 1,000. The lesson begins with a review of previous learning and a starter activity where students answer questions to warm up their mathematical thinking. The class then moves to the main teaching input, where children apply their understanding of multiplication and division by 10, 100, and 1,000 to solve related problems. For instance, they are shown how to use a known multiplication fact, such as 36 × 5 = 180, to work out calculations that involve multiples of these numbers. Through partner discussions, they explore how scaling a number in the fact by 10, 100, or 1,000 affects the product, thereby enhancing their ability to perform mental calculations with larger numbers.

Students then engage in a variety of activities to reinforce their knowledge. They compare different methods of multiplying, such as breaking down a number like 20 into two steps, and discuss the similarities and differences between these strategies. When it comes to division, they are introduced to a diagrammatic approach for dividing large numbers, such as 7,200 ÷ 200, by breaking the process into smaller, more manageable steps. Group work and independent activities further consolidate their understanding, with differentiated worksheets available to cater to varying levels of proficiency. To conclude the lesson, a plenary session allows for sharing answers and discussing different strategies, ensuring that students recognise the connection between known facts and new calculations, and can articulate how they arrived at their answers, whether working towards the expected level or delving into greater depth.
