Mastering 3-Digit Addition with Regrouping

Samantha from SPO resources demonstrates how to solve a three-digit addition problem with regrouping using base 10 blocks. She explains the process of representing numbers with blocks, regrouping in the ones and tens places, and using the standard algorithm to find the sum. The video encourages viewers to practice the strategy and offers guidance on where to find additional help if needed.
