Decimals
You can have an infinite amount of digits after a decimal. But in fourth grade, you only have to know about the first three places: the tenths place, hundredths place, and the thousandths place. It may seem backward, but a digit in the thousandths is actually SMALLER than a digit in the tenths place. That right! 0.008 (eight thousandths) is a SMALLER number than 0.8 (eight tenths).
It is important that you know what the first three places after the decimal are. Use the chart below to help you. You can also refer to your math notebook. You should already know the place values of whole numbers, so look at the blue section to learn about decimal values. Just like with whole numbers, digits have LESS VALUE as you move to the right (-->).
Do you notice anything strange about the the FIRST PLACE after the decimal?
There is no "oneths" place. Instead, the first place value is the tenths place!
ALSO, notice how each place value after the decimal has "ths" on the end of it. This is because every place value after the decimal represents a FRACTION of a number.
