Understanding Base 10 Models

The video tutorial from Underwater Math introduces base 10 models, which are blocks representing place values such as ones, tens, hundreds, and thousands. It explains how to create a place value chart and demonstrates how to use these models to represent numbers. The tutorial covers the construction of models for each place value and shows how to count and write numbers using these models. The video concludes with a motivational message, encouraging viewers on their learning journey.
