Comparing Numbers and Equality Concepts

In this math lesson, Teacher JJ introduces the concept of comparing numbers using symbols such as equal, greater than, less than, and not equal. The lesson uses practical examples involving seashells and the alligator mouth method to illustrate these concepts. Students are guided through various scenarios to understand how to use these symbols effectively. The lesson concludes with an activity from the math book to reinforce learning.
