Using Bar Models for Multiplication

This video tutorial explains how to use bar models to solve multiplication problems. It begins with an introduction to bar models and demonstrates solving two multiplication problems: 8 times a number equals 32, and 5 times 5 equals 25. The video highlights the use of bar models to visualize and solve these problems effectively.
