Lesson Plan: Introduction to Fractions
Subject: Mathematics
Duration: 30 Minutes
Grade Level: 3-4
Objectives
By the end of this lesson, students will be able to:
- Understand the concept of fractions as parts of a whole.
- Identify and create simple fractions using visual aids.
- Compare and order basic fractions.
Materials Needed
- Whiteboard and markers
- Fraction circles or pie charts
- Printed fraction strips
- Worksheets for practice
- Scissors and glue
Introduction (5 Minutes)
- Warm-Up Activity: Begin the lesson with a short introduction about fractions. Ask students if they have ever shared a pizza or cake and how they would divide it among friends.
- Discussion: Explain that fractions represent parts of a whole, using the pizza example. Display a fraction circle on the board and explain how different sections represent different fractions (1/2, 1/4, etc.).
Direct Instruction (10 Minutes)
-
Define Fractions:
Explain the numerator and denominator. Use simple language:
- Numerator: The top number that indicates how many parts we have.
- Denominator: The bottom number that shows the total number of equal parts the whole is divided into.
-
Visual Representation:
Use fraction circles or pie charts to visually represent the concept of fractions. Show examples such as 1/2, 1/3, and 1/4.
-
Creating Fractions:
Demonstrate how to create fractions using the printed fraction strips. Cut them into different parts and encourage students to participate.
Guided Practice (10 Minutes)
- Activity: Hand out the fraction strips to each student. Ask them to color a specified fraction of the strip (e.g., color 1/3 of the strip red).
- Pair Work: Have students work in pairs to compare their fractions. Ask guiding questions such as:
- Which fraction represents more/less?
- How can we order these fractions from smallest to largest?
Independent Practice (5 Minutes)
- Worksheet: Distribute a worksheet that includes:
- Matching fractions to their visual representations.
- Simple fraction comparison (e.g., which is greater: 1/4 or 1/3?).
- A section for students to draw and shade a fraction of a shape (e.g., shade 1/2 of a circle).
Conclusion (5 Minutes)
- Review: Discuss the answers to the worksheet as a class.
- Key Takeaways: Reinforce the definition of fractions, the concepts of numerator and denominator, and the importance of understanding fractions in everyday life.
- Exit Ticket: Ask students to write down one thing they learned about fractions on a sticky note and place it on the board as they leave.
Assessment
- Assess student understanding through observations during pair work and the completion of worksheets.
- Use exit tickets to gauge individual student learning and identify areas needing reinforcement in future lessons.
This lesson plan provides a structured approach to teaching fractions, suitable for a 30-minute time frame, encouraging both group interaction and individual engagement.
