About this resource
Description
Converting decimals is one of the first big ideas students meet when they move from whole numbers to fractions and decimals. This converting decimals worksheet helps 4th grade students see that tenths and hundredths can be written two ways, as a fraction or as a decimal, and that both forms name the very same amount.
The worksheet opens with a worked example that shows how to change 3/5 into 6/10 and then into 0.6. In Part A, students write six fractions as decimals, including fractions such as 3/5 and 1/4 that must first be changed to tenths or hundredths. In Part B, they turn six decimals back into fractions with a denominator of 10 or 100. Part C asks students to decide whether a classmate is correct and explain their thinking in writing. Use it as guided practice, independent work, or a quick check after a lesson on decimal notation.
What’s Included
- One printable converting decimals worksheet for 4th grade
- A worked example of changing a fraction to tenths and then to a decimal
- Twelve conversion problems: six fractions to decimals and six decimals to fractions
- One written-explanation problem about tenths and hundredths
- A complete answer key
Why This Worksheet Helps Kids
First, it builds a strong link between fractions and decimals, so students understand that 0.4 and 4/10 are the same number. Second, it practices equivalent fractions with denominators of 10 and 100, a key 4th grade standard. Third, the explanation question asks students to reason about place value instead of only following steps, which deepens understanding and helps prepare them for testing.
Ideas for Teachers and Parents
Before students begin, shade a hundreds grid together and name the amount as a fraction and as a decimal. Students can also use money, since a dime is one tenth of a dollar and a penny is one hundredth. After the page is done, have partners explain Part C to each other out loud. This 4th grade decimals worksheet also works well as homework or a math center review.
