Teaching tips and what to try next

Read the decimal point as "and" (4.07 is "four and seven hundredths"), and name the last place to know the word form. Expanded form (4 + 0.07) shows each digit's value. Next, try Comparing Decimals to Thousandths or Rounding Decimals.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

This fifth grade place value worksheet practices the three ways to write a decimal. Part A gives numbers such as 43.202 and asks for expanded form (40 + 3 + 0.2 + 0.002). Part B gives word form, such as "twenty-three and seventeen hundredths," and asks for standard form. Part C gives expanded form with fractions, such as 3 x 10 + 2 x 1 + 4 x (1/10) + 9 x (1/1000), and asks for the standard number.

Every number in Parts A and C has exactly one zero digit after the decimal point. Those zeros are where most mistakes happen, so they get extra attention here. Each of the 10 versions has new numbers.

How to use it: draw a quick place-value chart with tens, ones, tenths, hundredths and thousandths, and have your child write each digit in its column before answering. Point out that "and" marks the decimal point in word form, and that the last place named tells how many digits come after it: "seventeen hundredths" needs two digits (0.17), while "seventeen thousandths" needs three (0.017).
