Addition Strategies and Concepts

The video tutorial by Miss B covers the concept of regrouping with addition for second-grade students. It begins with an introduction to the topic, followed by detailed examples using base 10 models and vertical addition methods. The examples include adding numbers like 35 + 27, 53 + 68, and 56 + 37, demonstrating how to regroup ones into tens. The tutorial emphasizes understanding the process, which aligns with common core math standards. The video concludes with a summary and a call to action for viewers to subscribe.
