Comparing Decimals Using Place Value Disks

The video tutorial explains how to compare two decimal numbers, 2.1 and 2.088, using a decimal place value chart. It guides viewers through the process of comparing digits starting from the greatest place value, the ones place, and moving to the tenths place. Since the ones digits are the same, the comparison moves to the tenths place, where 1 is greater than 0, concluding that 2.1 is greater than 2.088.
