Addition, Subtraction, Multiplication and Division - Adding Whole Numbers with more than 4-digits - Presentation

The focus of the lesson is on adding whole numbers that exceed four digits, a crucial skill in the broader topic of the four operations: addition, subtraction, multiplication, and division. Students are introduced to the concept using a place value grid and counters to visually represent the numbers and their respective values. The column method, a traditional and effective approach to addition, is employed alongside the concrete representation. This method is demonstrated through the calculation of sums such as 4,434 + 3,325, where students are encouraged to consider how each column is affected during the addition process and the significance of carrying over values when necessary.

Further activities involve adding numbers with varying digits, emphasising that the length of the numbers does not impede the addition process. Students are prompted to create stories that contextualise the calculations, enhancing their understanding of the practical application of addition in real-life scenarios. The lesson also challenges students with reasoning tasks, such as identifying missing numbers in a sequence and understanding the process of exchanging when sums exceed certain place values. Independent work consolidates the learning, with students cutting out problems to solve and recording their answers, fostering both computational accuracy and independence.
