Place value - Round numbers within 100,000 - Planning

In the second week of Autumn term, Year 5 students delve into the concept of rounding numbers within 100,000. The lesson aims to solidify their understanding of rounding to the nearest 10, 100, 1,000, and 10,000. Key vocabulary such as 'rounding', 'multiples', 'nearest', and 'place value' are crucial to the lesson, with resources like worksheets, presentations, and vocabulary cards available to support learning. The class begins with a recap of previous rounding techniques and quickly moves on to practical application. The teacher models how to round a number like 25,617 to various place values, emphasising the importance of the digit in the next smallest place value column to determine whether to round up or down. Students then get hands-on experience with rounding through a series of activities, including rounding air mileages to the nearest 1,000, which encourages them to articulate the process clearly as if explaining it to a younger student.

Throughout the lesson, children engage in independent and group work, applying their rounding skills to a range of starting numbers and recording their findings. They explore why rounding a 5-digit number to the nearest 100 or 1,000 might yield the same result, and discuss the relevance of rounding to different place values in real-world contexts. To consolidate their learning, students reflect on the skills they've used, such as interpreting number lines and applying rounding rules, and consider any aspects they found challenging. The lesson is differentiated to cater to varying levels of ability, from those working towards fluency to those capable of greater depth, with activities designed to deepen understanding of rounding in different scenarios. Students are encouraged to remember key concepts and justify their reasoning, ensuring a comprehensive grasp of rounding numbers within 100,000.
