Comparison Problems in Math

The video tutorial introduces the comparison box strategy for solving math problems, particularly in third-grade math. It explains how to visually represent problems using comparison boxes and provides examples involving crackers, marbles, and goldfish. The tutorial also covers more complex problems with larger numbers and emphasizes the importance of choosing the right strategy for different types of problems.
