Order and compare whole numbers and decimals to two decimal places

Order whole numbers and decimal (to the hundredths column) from least to greatest or greatest to least. Compare two numbers or decimals and find which one is greater, less than, or equal to ( <, >, =)

To achieve accuracy, the child should line up the numbers being compared to make sure they are comparing the digits in the same place value. They can visually see which number is greater (9>8, therefore, 298,468,392 > 285,631,218)

i.e.) 298,468,392

285,631,218

(2)

Remind children to begin comparing numbers with the largest place value, and not to begin in the ones column.

i.e.) 289,785

387,587

(3)

Practice ordering numbers by using the place value chart as a tool to organize the numbers.

(4)

Know symbols accurately:

> the “less than” sign points to the lower number

8<9

< the “greater than” sign want to eat the largest number (the mouth is open to eat the larger #)

9>8
