Expanded Form and Place Value

This is a one day lesson to teach place value in expanded form using place value tents and number dice to form numbers up to 10,000.  Students pretend to be doctors operating on a number to expand it. The dice game allows students to work individually to create a standard number. This is a whole group lesson for demonstrating and practing with standard and expanded form. This could also be used for differentiated instruction for struggling students.
