Understanding Composition and Decomposition of Numbers

This video tutorial introduces the concepts of composing and decomposing numbers up to 10,000 for 4th-grade students. It begins with an overview of the learning objectives, followed by a detailed explanation of how to compose numbers by understanding place values. The video includes practice problems to reinforce learning. It then transitions to decomposing numbers, breaking them down into smaller parts based on place values. The tutorial concludes with a summary and encouragement for students to continue practicing.
