This resource focuses on helping students master the concept of place value in whole numbers up to 100,000. The lesson outlines objectives for identifying the value of specific digits and writing numbers in both standard and expanded form. It includes a worked example demonstrating how to find the value of a digit based on its position in a number, like determining that the 5 in 45,672 represents 5,000. Students will engage with activities that encourage them to practice identifying and expressing numbers in expanded form, and reflect on their understanding through tasks that challenge their critical thinking about place values. The resource is designed to develop a clear understanding of the significant differences in digit values based on their locations within a number.
