Understanding Expanded Notation Concepts

This video is part of a 12-day review of fourth-grade mathematics, focusing on expanded notation and comparing and ordering numbers. The instructor uses examples from the 2017 released STAAR test in Texas to explain expanded notation with both whole numbers and decimals. The video also covers how to compare and order numbers using less than signs, providing a step-by-step approach to solving these types of problems.
