Comparing Numbers with Symbols for Second Graders

The video tutorial teaches second graders how to compare numbers using greater than, less than, and equal to symbols. It introduces the concept of place value and uses examples with single, two, and three-digit numbers. The character Ali the Alligator helps students remember the symbols by 'eating' the larger numbers. The tutorial also includes practice exercises and explains how to identify equal numbers.
