Decimals for Kids: Tenths and Hundredths Explained (Grade 4 Math)

Hi, I'm Luna from DoodleBeez. Today we are learning about decimals. Decimals are a way to write parts of a whole, like tenths and hundredths, using a tiny dot called the decimal point.

Here is one whole cut into ten equal parts. Each part is one tenth. Three parts are shaded, so that is three tenths. We can write it as a fraction, or as the decimal zero point three.

After the decimal point, the first place is tenths and the second place is hundredths. In the number two point four seven, the two is two ones, the four is four tenths, and the seven is seven hundredths.

Hundredths are easy to see with money. One dollar is one hundred cents, so one cent is one hundredth of a dollar. Twenty five cents is twenty five hundredths, written as zero point two five dollars.

Here is a cool fact. Five tenths and fifty hundredths are the same amount. Zero point five and zero point five zero are equal, just like half a dollar is the same as fifty cents.

Now it's your turn. Which is bigger, zero point four or zero point three five? Pause and try. Zero point four is the same as zero point four zero. Forty hundredths is more than thirty five hundredths, so zero point four is bigger.

Great job! Remember, the first place after the decimal point is tenths, and the second place is hundredths. Ten hundredths make one tenth. Practice decimals in the Math Lab at doodlebeez.com. See you next time!
