Lesson Plan: Introduction to Fractions
Subject: Mathematics
Grade: 5
Duration: 30 minutes
Learning Objectives
By the end of the lesson, students will be able to:
- Understand the concept of fractions as parts of a whole.
- Identify and create equivalent fractions.
- Compare and order fractions with like denominators.
Materials Needed
- Whiteboard and markers
- Fraction circles or bars
- Worksheets for practice
- Notebooks and pencils
Lesson Outline
Introduction (5 minutes)
- Start with a brief discussion about the concept of fractions. Ask students to share examples of fractions they encounter in real life (e.g., pizza slices, measuring ingredients).
- Explain that fractions represent a part of a whole and consist of a numerator (the top number) and a denominator (the bottom number).
Direct Instruction (10 minutes)
- Use fraction circles or bars to visually represent different fractions.
- Example: Show 1/2, 1/4, and 3/4 using the fraction circles.
- Explain equivalent fractions by demonstrating how different fractions can represent the same part of a whole. For example, show that 1/2 = 2/4 = 4/8 by dividing the circles.
Guided Practice (10 minutes)
- Distribute worksheets that include exercises on identifying and creating equivalent fractions.
- Problems might include:
- Write three equivalent fractions for 1/3.
- Compare the fractions 2/5 and 3/5 (which is larger?).
- Walk around and provide support as students work through the tasks.
Independent Practice (5 minutes)
- Give students a quick assessment where they must compare the following fractions:
- Students will also create equivalent fractions for 2/6.
Conclusion (5 minutes)
- Review key concepts learned during the lesson.
- Ask students to share what they learned about fractions and how they can see them in everyday life.
- Answer any remaining questions before dismissing students.
Homework
- Complete the following tasks:
- Write three equivalent fractions for 3/5.
- Compare and order the following fractions from smallest to largest: 4/6, 2/6, 5/6.
- Create a visual representation of 1/4 using drawings or cut-out shapes.
Homework Answers
- Three equivalent fractions for 3/5 could be: 6/10, 9/15, 12/20.
- Order from smallest to largest: 2/6, 4/6, 5/6.
- Acceptable visual representations will vary but should clearly illustrate a shape divided into 4 equal parts with 1 shaded.
Assessment
During independent practice, assess students on their ability to compare and create equivalent fractions. Homework will also provide further insight into their understanding of the material.
