Adding and Regrouping with Place Value

The video tutorial covers the strategy of adding numbers using place value and regrouping. It begins with an introduction to the concept, followed by a problem involving the addition of trading cards. The instructor demonstrates the use of place value blocks to visualize the addition process. The video also explains the partial sums method and the standard algorithm for addition, providing multiple approaches to solve the problem. The tutorial emphasizes understanding place value and regrouping to achieve accurate results.
