In this lesson, students explore the inverse relationship between addition and subtraction, and the additive identity of zero. First, they act out inverse number stories on a number path in the classroom and write a number sentence to model it. Then they model a number story using their fingers and writing a number sentence for it. Finally, students model on the number path what happens when you add or subtract zero from an amount.
