Title: Simplifying Fractions
Grade Level: 4th Grade
Objective:  Students will understand the concept of simplifying fractions.  Students will be able to simplify fractions using common factors.  Students will practice simplifying fractions through handson activities and worksheets.
Materials:  Fraction manipulatives (e.g., fraction circles, fraction bars)  Whiteboard or chart paper  Markers or chalk  Simplifying Fractions Worksheet (prepared in advance)  Pencils
Procedure:

Introduction (10 minutes) a. Begin the lesson by reviewing the concept of fractions and their parts (numerator and denominator). b. Ask students if they have ever encountered fractions that seem complicated or difficult to understand. c. Explain that today, they will learn a strategy called “simplifying fractions” to make fractions easier to work with.

Exploring Simplifying Fractions (15 minutes) a. Distribute fraction manipulatives to each student or group. b. Model how to simplify fractions using manipulatives. For example, show how to simplify 4/8 by dividing both the numerator and denominator by their greatest common factor (GCF), which is 4. c. Provide additional examples and encourage students to simplify fractions using manipulatives. d. Discuss the importance of finding the GCF to simplify fractions.

WholeClass Practice (15 minutes) a. Write a few fractions on the whiteboard or chart paper, such as 6/12, 10/20, and 16/24. b. Ask students to identify the GCF for each fraction and guide them in simplifying the fractions. c. Discuss the simplified fractions as a class and reinforce the concept of simplification.

Independent Practice (15 minutes) a. Distribute the Simplifying Fractions Worksheet to each student. b. Instruct students to simplify the given fractions using the GCF. c. Circulate the classroom to provide assistance and monitor progress.

Group Activity: Simplifying Fraction Puzzles (15 minutes) a. Divide the class into small groups. b. Provide each group with a set of fraction puzzles (prepared in advance) that require simplification. c. Instruct students to work together to solve the puzzles by simplifying the fractions. d. Encourage students to discuss their strategies and reasoning with their group members.

Conclusion (5 minutes) a. Gather the class and review the concept of simplifying fractions. b. Ask students to share any challenges they faced during the lesson and how they overcame them. c. Summarize the importance of simplifying fractions to make them easier to work with in various mathematical operations.
Extensions:  Challenge advanced students to simplify fractions with larger numerators and denominators.  Introduce mixed numbers and guide students in simplifying them.  Provide additional worksheets or online resources for extra practice.
Assessment:  Observe students’ participation during wholeclass and group activities.  Review completed worksheets to assess individual understanding of simplifying fractions.  Ask students to explain the process of simplifying fractions in their own words.
