Understanding Base 10 Concepts

The video tutorial explains how to regroup numbers using the base 10 system. It begins with an introduction to regrouping and the number system, followed by a detailed explanation of base 10 blocks and place value. The tutorial provides examples of regrouping ones, tens, and hundreds, and concludes with advanced regrouping techniques. The key focus is on trading groups of ones, tens, and hundreds to simplify number models.
