Comparing Decimals with Base Ten Blocks

To compare two decimals, like 2.1 and 2.08, model each number on a decimal place value chart. To find which number is greater, start by comparing the greatest place value (the ones place). The numbers have the same digit in the ones place, so compare the next greatest place value (the tenths place). The number 2.1 has more tenths than the number 2.08, so 2.1 is greater than 2.08. The comparison can be written with an inequality symbol as 2.1 > 2.08.
