Decimals are a shorthand way to write fractions and mixed numbers with denominators that are powers of 10 , like 10,100,1000,10000, etc. If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. For example, the decimal 0.3 is the same as the fraction 310 .

Show them that tenths are always immediately to the right, followed by hundredths and thousandths. Over-pronounce tenths and hundredths to avoid confusing decimal place values with tens and hundreds.
