How to Read Decimals
A Simple Visual Guide for Kids
Decimals confuse kids when they learn to say "point four five" instead of understanding place value. This guide teaches the right way — so decimals actually make sense.
The Golden Rule:
Say "and" for the decimal point, then say the place value
3.45 = "three and forty-five hundredths"
Understanding Decimal Place Value
Each position after the decimal has a special name
Decimals are like fractions with denominators of 10, 100, or 1000. The decimal point separates the whole number from the part.
0.1 is one tenth. 0.7 is seven tenths. Say it as "seven tenths" not "point seven."
0.01 is one hundredth. 0.45 is forty-five hundredths. Say the whole number then "hundredths."
0.001 is one thousandth. 0.375 is three hundred seventy-five thousandths.
3.45 is "three and forty-five hundredths." Never say "three point four five" — that skips the place value meaning.
Many kids think 0.45 > 0.7 because 45 > 7. But tenths are larger than hundredths. 0.7 = 0.70, which is 70 hundredths.
