L5 Count in Multiples of 1,000

This Year 4 Place Value lesson— “Count in Multiples of 1,000” —supports children in developing a secure understanding of thousands and how they behave within the number system. Building on previous lessons on multiples of 10, 100, 25 and earlier Year 3 content, the session revisits place value patterns before introducing the thousands column as the next step in scaling up. The lesson begins by comparing counting in 10s and 100s, identifying how the tens digit changes when counting in 10s and how the hundreds digit changes when counting in 100s. Children then explore how counting in 1,000s follows the same pattern but requires an additional place value column. Using visuals, teachers demonstrate how the thousands digit changes while other digits remain the same, helping pupils clearly see how numbers grow at this scale. Practical models such as Base 10 and place value counters are introduced, with discussion about why counters are more efficient for representing thousands (because Base 10 equipment becomes impractically large at this level). Pupils then apply their knowledge to a set of differentiated word problems, selecting at least five to solve and using place value counters where needed. Problems vary in structure, supporting both forward and backward counting in 1,000s and integrating contexts such as measurement. The plenary focuses on Esin’s reasoning error—believing that 4,100 is part of a counting sequence in 1,000s—allowing children to discuss how the hundreds digit reveals that this cannot be correct. The lesson includes clear misconceptions, key reasoning prompts and opportunities for assessment, helping children build confidence in manipulating four-digit numbers and understanding how multiples of 1,000 behave. Perfect for a worksheet-free, structured and high-impact Year 4 Place Value lesson.
