Comparing Numbers and Their Values

The video tutorial introduces students to comparing numbers, explaining the use of symbols for greater and smaller numbers. It introduces the crocodile method as a visual aid for understanding these symbols. The tutorial outlines three rules for comparing numbers: Rule 1 states that numbers with more digits are greater; Rule 2 involves comparing the leftmost digit when numbers have the same number of digits; and Rule 3 suggests comparing the next digit if the leftmost digits are equal. The video concludes with practice questions and a worksheet for students to reinforce their learning.
