Comparing Two-Digit Numbers: Greater Than, Less Than, Equal To

This video tutorial teaches how to compare two-digit numbers using comparison symbols like greater than, less than, and equal to. The lesson uses the metaphor of an alligator's mouth to represent these symbols, emphasizing that the mouth opens towards the larger number. Through examples, such as comparing 32 and 14, and 21 and 26, the tutorial explains the process of comparing tens and ones. It also covers equality with an example of the number 58. The video includes interactive practice questions to reinforce learning.

• A minus sign (-)

• An alligator mouth opening towards the larger number
