Comparing and Ordering Two-Digit Numbers

The video tutorial explains how to compare numbers using visual block representations. It covers comparisons between pairs of numbers such as 55 and 71, 55 and 51, 41 and 14, and 62 and 26. The tutorial also demonstrates how to order a set of numbers in ascending order by analyzing the number of tens and units. The concept of using symbols for greater than and less than is introduced, with a mnemonic involving a crocodile snapping at the larger number.
