Place value - 100s, 10s and 1s - Planning

Year 3 students dive into the world of place value with a focus on the hundreds, tens, and ones in a three-digit number. The National Curriculum objectives for this lesson include identifying and representing numbers in various ways, understanding and finding 10 or 100 more or less than a given number, and recognising the place value of each digit in a three-digit number. Students will also compare and order numbers up to 1000, read and write these in both numerals and words, and solve related number problems. Key vocabulary such as 'place value', 'partition', and 'representation' are introduced, alongside practical tools like base 10 manipulatives, place value counters, and part whole models to help visualise and understand these concepts.

The lesson begins with a starter activity where children recap on the previous learning and then move on to identifying numbers represented in various forms, recording them in both numerals and words. They use stem sentences to articulate their understanding of the numbers shown. The lesson progresses with practical activities, where children use manipulatives to represent three-digit numbers in multiple ways, and reasoning challenges to deepen their understanding of the value of each digit within the number. Throughout the lesson, common misconceptions are addressed, such as the role of zero as a placeholder and the value of digits in different positions. The lesson concludes with a reflective 'Give me five' activity, where students assess their learning, the skills used, and what they found challenging, ensuring they remember the key concepts of partitioning three-digit numbers into hundreds, tens, and ones.
