👉 Note: This worksheet is ideal for students who are new to decimals or need a review.
2. Decimal Addition and Subtraction Worksheet
This worksheet focuses on the practical application of adding and subtracting decimals through word problems:
- Problems involving money, measurements, or distance.
- Word problems that require alignment of decimal points for addition/subtraction.
Here's a sample problem:
| Alex bought 3.25 kg of apples and 1.75 kg of pears. How many kg of fruit did he buy in total? |
⚠️ Note: Make sure students understand that alignment of decimal points is critical for accuracy.
3. Decimal Multiplication Worksheet
Mastering multiplication with decimals can be tricky. This worksheet provides:
- Multiplication of decimals by whole numbers.
- Problems involving the multiplication of two decimals.
- Word problems that require multiplication to solve real-life scenarios.
Here's an example:
| If one liter of paint covers 4.5 square meters, how much paint is needed to cover 25.5 square meters? |
4. Decimal Division Worksheet
Division with decimals often requires extra care:
- Dividing decimals by whole numbers.
- Dividing a decimal by another decimal.
- Word problems to practice understanding division in context.
A sample question might look like this:
| 5 children share 12.5 apples equally. How many apples does each child receive? |
📌 Note: Encourage students to practice long division, as calculators often do not show the process.
5. Real-World Application of Decimals Worksheet
This final worksheet pushes students to apply their knowledge of decimals to everyday situations:
- Calculating tips, sales tax, and discounts in shopping scenarios.
- Estimating and measuring lengths, weights, and volumes.
- Financial word problems involving budgeting and savings.
