Place value - Rounding to the nearest 100 - Worksheet

The lesson on rounding to the nearest 100 is aimed at helping children understand place value and the concept of multiples of 100. It is designed to meet the National Curriculum objective of rounding any number to the nearest 100. To facilitate this learning, differentiated sheets and teaching slides are used as resources. The key vocabulary for the lesson includes terms such as multiples, rounding, place value, thousands, hundreds, tens, and ones. Through the exercises, students learn to identify the tens column as the determinant for rounding numbers to the nearest hundred. They practice using number lines to visually grasp which multiples of 100 a number falls between, enhancing their fluency and precision in the process.

Children are encouraged to engage in reasoning and problem-solving activities where they answer questions that may require a response of 'Always', 'Sometimes', or 'Never'. These exercises challenge them to provide examples and use investigative skills to understand the principles of rounding. For instance, they explore scenarios where numbers with a five in the tens, hundreds, or ones column are rounded to the nearest hundred. Additionally, they apply their knowledge to identify odd numbers out and even use Roman numerals to round numbers. The lesson not only solidifies their understanding of rounding but also integrates critical thinking with mathematical concepts.
