Decimals and money notation
Written by Adi Ackerman, Head Teacher
"Decimals and money notation" is written for 4th Grade (Ages 9-10), and it covers Common Core 4.MD.A.2. If your little one is a year younger but already steady on decimals, the page still works. You may just need to read the instructions out loud. And if they are older and decimals and money notation never quite stuck, this is a short review rather than busywork.
Free printable decimals and money notation worksheet for 4th grade students. Part of our decimals and money notation collection. Aligned to Common Core standards.
How do I use this worksheet?
Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently, since students at this age benefit more from productive struggle than from being walked through each step, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These decimals and money notation worksheets work well as daily practice, homework, or a focused review activity.
What students will practice
- Students will recognize and apply decimals and money notation concepts using written strategies and place-value reasoning.
- Students will solve problems involving decimals and money notation with increasing accuracy and confidence.
- Students will connect decimals and money notation skills to real-world situations and explain their reasoning clearly.

Common Core State Standards
Measurement and Data · 4th Grade
Standard: Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

What does this worksheet teach?
⌄
These decimals and money notation worksheets for 4th grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter decimals and money notation from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 4th grade. Practicing decimals and money notation at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.
Can I use this decimals and money notation worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 4th Grade decimals, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with decimals and money notation. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How does money notation directly model decimal place value?
⌄
Dollars represent whole numbers, dimes represent tenths, and pennies represent hundredths - making money a perfect concrete model for two-decimal-place numbers in everyday life.
What common errors do students make when writing money as a decimal?
⌄
Students often write cents without the leading zero (e.g., writing $.75 as $0.7 instead of $0.75) or forget to include the dollar sign and decimal point in the correct positions.
How can these worksheets support financial literacy alongside decimal learning?
⌄
Connecting decimal computation to buying, making change, and comparing prices gives students functional money skills while reinforcing the decimal concepts they need for standardized math assessments.
What decimal skills do 4th graders learn?
⌄
4th graders learn decimals as another way to write tenths and hundredths (CCSS 4.NF.C.6). They write fractions like 7/10 and 37/100 as 0.7 and 0.37, place decimals on number lines and grids, and compare two decimals to hundredths using >, < and = (4.NF.C.7). Money and metric lengths give the decimals everyday meaning.
How do you compare decimals in 4th grade?
⌄
Line up the decimal points and compare place by place from the left: ones, then tenths, then hundredths. Writing 0.5 as 0.50 makes it easy to see that 0.5 is greater than 0.47.
Do 4th graders add decimals?
⌄
Yes, in a limited way. They add tenths and hundredths by writing tenths as hundredths (3/10 + 4/100 = 34/100), which is 4.NF.C.5. Adding and subtracting decimals with the standard method is a 5th grade skill.
Is there an answer key for each worksheet?
⌄
Yes. Every one of the 30 new decimals sheets has an answer key, and the two page sheets have a two page key.
