Understanding Decimals
Decimals are a way of representing fractions that have denominators that are powers of ten. For example, 0.5 represents the fraction 5/10, and 0.75 represents the fraction 75/100. Understanding decimals is crucial as they are used in various real-life situations, such as money, measurements, and data analysis.

2. Place Value Exercises
Place value is foundational for understanding decimals. Include exercises that ask students to identify the place value of a given digit in a decimal number. For example:
- What is the value of the digit 7 in the number 4.783?
- Write the decimal number for the following: 3 tenths, 6 hundredths, and 2 thousandths.
3. Comparing and Ordering Decimals
Create problems that require students to compare and order decimal numbers. For instance:
- Which is greater: 0.56 or 0.65?
- Arrange the following numbers in ascending order: 0.45, 0.504, 0.5, 0.55.
4. Addition and Subtraction of Decimals
Incorporate addition and subtraction problems that involve decimals. Use real-world scenarios to make the problems relatable. For example:
- Sarah bought a pencil for $0.75 and an eraser for $0.50. How much did she spend in total?
- If a fabric piece measures 1.2 meters and another measures 0.75 meters, what is the total length of the fabric?
5. Multiplication and Division of Decimals
Include multiplication and division exercises that help students practice these operations with decimals. Examples can include:
- Multiply: 3.6 x 2.5
- Divide: 4.5 รท 0.9
6. Converting Fractions to Decimals
Provide a section that focuses on converting fractions into decimals. Students can practice with common fractions:
- Convert the following fractions to decimals:
1. 1/2
2. 3/4
3. 2/5
7. Real-Life Application Problems
Real-life application problems help students see the relevance of decimals in everyday life. Include problems such as:
- A store is having a sale where all items are 25% off. If a shirt costs $19.99, what is the discounted price?
- John scored 85.5 points in a game, and his friend scored 90.2 points. How many points did they score together?
8. Challenge Section
For advanced learners, include a challenge section with more complex problems. This could involve multi-step problems or those requiring critical thinking. For example:
- If a recipe calls for 2.5 cups of flour and you want to make half the recipe, how much flour will you need?
- Maria read 1.75 books each month for six months. How many books did she read in total?
Tips for Using Worksheet on Decimals in the Classroom
