These guided notes are designed to help students understand and practice writing whole numbers in expanded form, reinforcing their knowledge of place value. Students will learn how to break down numbers based on the value of each digit and express them as a sum of each digit multiplied by its place value. Through step-by-step instruction, place value charts, and scaffolded examples, students will see how expanded form shows the true value of each digit in a number. These notes support place value fluency and provide a strong foundation for operations with larger numbers and future math concepts.
