Subtraction with Regrouping for 2nd Graders

The video tutorial guides children through solving subtraction problems with regrouping. The teacher, who is feeling under the weather, uses two example problems to demonstrate the process of regrouping in subtraction. The first problem involves subtracting 16 from 25, and the second problem involves subtracting 27 from 80. The teacher explains each step clearly, encouraging students to follow along and solve the problems. The video concludes with a thank you message and a request to share and subscribe.
