Words to know

decimal point: The dot that separates the ones from the tenths.

tenths, hundredths, thousandths: The columns to the right of the point, each 10 times smaller.

decimal places: How many digits are to the right of the point.

placeholder zero: A 0 that keeps a digit in the right column.

divisor: The number you divide by.

Common mistakes

Your child lined up the last digits instead of the decimal points. Try writing both numbers in columns with the points directly above each other, and fill the empty places with zeros.

Your child put the decimal point in the wrong place after multiplying. Try this together: count the decimal places in both numbers and add them. That is how many places the answer needs.

Your child moved the decimal point in the divisor but not in the number being divided. Try moving both points the same number of places, then dividing.
