Title: Introduction to Fractions

Grade Level: 4th grade

Objective: - Students will understand the concept of fractions and be able to identify and represent fractions using models and symbols. - Students will be able to compare and order fractions. - Students will be able to add and subtract fractions with like denominators.

Materials: - Fraction manipulatives (e.g., fraction bars, fraction circles) - Whiteboard or chart paper - Markers - Worksheets or handouts with fraction problems - Pencils

Procedure:

1. Introduction (10 minutes) - Begin the lesson by asking students if they have ever shared a pizza or a cake with someone. Discuss how they divided the pizza or cake into equal parts. Explain that fractions are a way to represent these equal parts.

2. Understanding Fractions (15 minutes) - Introduce the concept of fractions by using fraction manipulatives. Show students a fraction bar and explain that it represents a whole. Demonstrate how to divide the bar into equal parts to represent fractions (e.g., 1/2, 1/3, 1/4). - Have students work in pairs or small groups to explore the fraction manipulatives and create their own fractions. Encourage them to write down the fractions they create.

3. Representing Fractions (15 minutes) - Review the concept of fractions using the whiteboard or chart paper. Write down different fractions and ask students to represent them using fraction manipulatives. - Discuss the different ways fractions can be represented, such as using fraction bars, fraction circles, or numbers.

4. Comparing and Ordering Fractions (15 minutes) - Introduce the concept of comparing and ordering fractions. Explain that when comparing fractions, the size of the denominator determines the size of the parts. - Provide examples of fractions and ask students to compare and order them. Use fraction manipulatives to help students visualize the fractions.

5. Adding and Subtracting Fractions (20 minutes) - Review the concept of adding and subtracting fractions with like denominators. Explain that when the denominators are the same, only the numerators need to be added or subtracted. - Provide examples of addition and subtraction problems with like denominators. Have students solve the problems individually or in pairs using fraction manipulatives or by writing the fractions.

6. Practice and Application (15 minutes) - Distribute worksheets or handouts with fraction problems for students to solve independently. Monitor their progress and provide assistance as needed. - After completing the worksheets, review the answers as a class and address any questions or misconceptions.

7. Conclusion (5 minutes) - Summarize the key concepts covered in the lesson, including understanding fractions, representing fractions, comparing and ordering fractions, and adding and subtracting fractions with like denominators. - Encourage students to continue practicing fractions in their daily lives, such as when dividing food or sharing objects equally.

Assessment: - Observe students’ participation and engagement during the lesson. - Review students’ completed worksheets or handouts to assess their understanding of the concepts covered. - Ask students to explain their thinking and reasoning when comparing, ordering, or solving fraction problems.
