Understanding Comparison Models in Math

This video tutorial introduces the comparison model, a type of bar model used to solve math problems by comparing different objects. The tutorial explains how to draw and use the model through an example problem involving ice cubes. It highlights the benefits of using comparison models and guides viewers in calculating totals using the model. The video concludes with encouragement for viewers to apply their new skills in problem-solving.
