This video is a lesson on how to use the distributive property to write equivalent expressions. The video starts by explaining how to break apart multiplication problems into smaller equivalent problems to make them easier to solve. The concept of using variables to represent a quantity that can change is also demonstrated. The video then goes on to provide examples of how to use the distributive property to find equivalent expressions with variables. The lesson concludes with two practice problems where the distributive property is used to find the total cost of tickets and locker rentals for friends to enter an amusement park.
