Expanded Notation

The video tutorial introduces the concept of expanded notation, using a place value chart to break down numbers into thousands, hundreds, tens, and ones. It provides examples with different numbers, including a 5-digit number, and demonstrates how to convert numbers from standard and word notation to expanded notation. The tutorial includes word problems to reinforce the concept, such as calculating total ticket sales, determining the number of apple trees producing fruit, and checking weight limits for an amusement park ride.
