Grade 3 - Addition - Decomposition or Place Value Split

In this video, we'll explore how third graders build on their understanding of place value, addition, and subtraction as they begin to tackle multiplication and division. One key strategy involves breaking down numbers by their place value to make addition easier. While this method may not always be the most efficient, it helps deepen students' understanding of math concepts. We'll also discuss the importance of staying organized and using tools like color-coding to enhance mathematical communication.
