Place value - Round numbers within 100,000 - Presentation

This educational resource offers a series of activities aimed at helping students master the concept of rounding numbers within the range of 100,000. The initial activity focuses on rounding a given number, such as 25,617, to the nearest 10, 100, 1,000, and 10,000. Students are encouraged to identify the relevant place value column when rounding to a specific place. For example, when rounding to the nearest 1,000, they would look at the thousands and hundreds columns to determine the rounded number. This activity is designed to enhance students' fluency and reasoning skills in the context of place value.

Further exercises involve rounding distances from Manchester airport to the nearest 1,000 miles, with destinations including New York, Sydney, and Hong Kong. This real-world application helps students understand when it is appropriate to round to the nearest 10, 100, or 1,000. Additionally, comprehensive tables are provided for students to practice rounding various start numbers to different place values. The resource also includes reasoning tasks, where students are prompted to notice patterns in rounded numbers and provide examples of numbers that exhibit similar rounding results. Critical thinking is fostered through discussions about the choice of place value column for rounding and the justification of their reasoning.
