4-Digit Addition Practice Challenges

In this video, Mr. J provides a tutorial on solving four-digit addition problems, focusing on the concept of regrouping, also known as carrying. The video includes four practice problems, each demonstrating the step-by-step process of adding numbers with regrouping. Mr. J explains how to handle each place value, from ones to thousands, and emphasizes the importance of regrouping when necessary. The video concludes with a summary and links to additional resources for further practice.
