Lesson Plan: Decimals

Subject: Mathematics
Topic: Decimals
Grade Level: Year 5
Duration: 30 minutes

---

Objective

By the end of this lesson, students will be able to:

• Understand the concept of decimals and their relationship to fractions.
• Compare and order decimal numbers.
• Perform basic addition and subtraction operations with decimals.

Materials Required

• Whiteboard and markers
• Decimal place value chart
• Worksheets containing decimal exercises
• Small objects or counters (e.g., buttons, blocks) for group activities
• Projector (optional)

Introduction (5 minutes)

Begin the lesson with a brief review of fractions, explaining how decimals can represent parts of a whole, similar to fractions.

Key Points to Discuss:

• A decimal is a way to express a number that is not whole.
• Decimals are based on powers of ten.

Example:
Show the class a model of a fraction, e.g., 1/2 and its decimal equivalent, 0.5.
Ask students if they can think of other examples of fractions and their decimal equivalents (e.g., 1/4 = 0.25).

Explanation of Concepts (10 minutes)

What is a Decimal?

Introduce the concept of decimals with the help of a decimal place value chart:

• Tenths (0.1)
• Hundredths (0.01)
• Thousandths (0.001)

Decimal Place Value Chart:

|   | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|---|---|---|---|---|---|---|---|---|---|----|
|   |   |   |   |   |   |   |   |   |   |    |
|   |        | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|   |        | 0 | . | 1 | 2 | 3 | 4 | 5 | 6 |

Emphasise the significance of each place value. For example, the “3” in 0.34 is in the tenths place, indicating three tenths.

Comparing Decimals

Discuss how to compare decimal numbers by aligning decimal points. Use examples such as:

• 0.5 vs 0.45
• 0.78 vs 0.8

Ordering Decimals

Explain how to order decimals from smallest to largest. Use sample numbers to demonstrate.

Guided Practice (5 minutes)

Provide a few examples on the whiteboard for students to solve as a class:

1. Compare the following decimals: 0.6 and 0.66
2. Order these decimals from smallest to largest: 0.3, 0.35, 0.33

Encourage students to share their reasoning for their answers as a class discussion.

Group Activity (5 minutes)

Divide the class into small groups of 3-4 students. Provide each group with counters. Give them a task to:

• Create their own decimal numbers using the counters.
• Compare and order their decimal numbers within the group.

Allow groups to present their decimal numbers and explain their comparisons to the class.

Individual Practice (5 minutes)

Distribute worksheets with decimal exercises that may include:

• Comparing and ordering a set of decimals.
• Basic addition and subtraction involving decimals (e.g., 0.75 + 0.25).

Example Worksheet Questions:

1. Order the following decimals: 0.56, 0.42, 0.5
2. Solve: 1.2 + 0.3 = ?
3. Solve: 2.5 - 0.7 = ?

Conclusion (5 minutes)

Wrap up the lesson by summarising the key concepts learned today about decimals:

• Understanding decimals and their place values.
• How to compare and order decimals.
• Adding and subtracting decimal numbers.

Encourage students to practice more with decimals at home by giving them resources or recommending their parents engage them with daily activities involving money or measurements.

Assessment

To assess understanding, collect worksheets and review responses. Provide feedback on any errors and clarify misconceptions in the next lesson.

Further Reading/Homework

Assign students to find real-world examples of decimals, such as prices at a store or scores in a game, to bring them into the next class for discussion.
