Addition, Subtraction, Multiplication and Division - Order of operations - Planning

In the Year 6 curriculum, students delve into the complexities of mixed operation calculations, focusing on the correct order of operations. This concept is crucial as it dictates the sequence in which calculations should be performed to arrive at the correct answer. The lesson introduces BIDMAS—Brackets, Indices, Division, Multiplication, Addition, and Subtraction—as the convention to follow. This hierarchy is not just about working from left to right; it requires understanding and applying the specific order to solve mathematical problems accurately. The class will explore how brackets influence the outcome of calculations and the importance of their correct placement. Through a combination of class teaching, partner discussions, and independent practice with worksheets, students will learn to navigate calculations involving multiple operations, ensuring they grasp the significance of BIDMAS in obtaining the true value of an expression.

During the lesson, students engage in a variety of activities designed to consolidate their understanding of the order of operations. They will be challenged to identify and correct misconceptions, such as processing calculations strictly from left to right without regard for BIDMAS, or neglecting to solve expressions within brackets first. The lesson also includes group work where students debate the validity of given calculations and rectify any false ones. To further deepen their comprehension, they will participate in reasoning activities that require them to apply the order of operations to complex problems. The lesson concludes with a reflective 'Give me five' session, prompting students to consider what they've learned, the skills they've utilised, and the key points they need to remember. Differentiated worksheets support students working at various levels, from those aiming to understand the basics to those ready to tackle calculations with multiple operations at greater depth.
