Multiplication and Division (2) - Multiply 4 digits by 2-digits (Basic Practice) - Planning

In a Year 5 mathematics lesson, students are introduced to the concept of multiplying 4-digit numbers by 2-digit numbers, expanding on their previous knowledge of multiplying 3-digit by 2-digit numbers. The lesson includes a range of resources such as worksheets and a presentation, and it is supported by key vocabulary terms like 'multiplication', 'placeholder', 'column method', and 'partition'. The session begins with a starter activity to refresh the pupils' existing knowledge, followed by a series of activities designed to guide them through the process of multiplication using the column method. For example, Activity 1 involves discussing partially completed calculations and understanding the role of zero as a placeholder, while Activity 2 challenges the students to complete calculations with missing steps, emphasizing the importance of partitioning and exchanging.

The lesson progresses with more complex tasks such as comparing pairs of calculations to determine the largest product, which requires a thorough understanding of the column multiplication method. Group work and independent activities cater to different levels of comprehension, with differentiated worksheets to ensure all students are engaged and learning effectively. The plenary session encourages reflection, asking students to consider what they have learned, the skills they have used, and any difficulties they faced. The lesson aims to ensure that students not only grasp the steps involved in the multiplication process but also understand the importance of placeholders and the logic behind the layout of calculations. By the end of the lesson, students should be able to confidently multiply 4-digit numbers by 2-digit numbers and compare the results, with the more advanced learners demonstrating greater depth in their understanding and ability to show their working out clearly.
