Title: Introduction to Fractions

Grade Level: 4th Grade

Objective: - Students will be able to understand the concept of fractions and identify the numerator and denominator. - 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 circles, fraction bars) - Whiteboard or chart paper - Markers - Worksheets 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. - Introduce the concept of fractions by explaining that fractions represent parts of a whole. Write the fraction 1/2 on the board and explain that the numerator (top number) represents the number of parts we have, and the denominator (bottom number) represents the total number of equal parts.

2. Exploring Fractions (15 minutes) - Distribute fraction manipulatives to each student or group of students. - Instruct students to use the manipulatives to represent different fractions, such as 1/2, 1/3, and 1/4. Have them identify the numerator and denominator for each fraction. - Ask students to share their representations with the class and explain how they determined the numerator and denominator.

3. Comparing and Ordering Fractions (15 minutes) - Write several fractions on the board, such as 1/2, 1/3, and 1/4. - Discuss with students how to compare fractions by looking at the denominators. Explain that when the denominators are the same, the fraction with the larger numerator is greater. - Have students work in pairs or small groups to compare and order the fractions on the board. Provide guidance and support as needed. - Ask students to share their comparisons and ordering with the class, and discuss any misconceptions or difficulties they encountered.

4. Adding and Subtracting Fractions with Like Denominators (20 minutes) - Review the concept of adding and subtracting fractions with like denominators. - Provide students with worksheets containing addition and subtraction problems with fractions. Instruct them to solve the problems independently or in pairs. - Circulate the classroom to provide assistance and monitor student progress. - After completing the worksheets, review the answers as a class, discussing the steps taken to solve each problem.

5. Conclusion (5 minutes) - Summarize the key points of the lesson, emphasizing the concept of fractions, identifying the numerator and denominator, comparing and ordering fractions, and adding and subtracting fractions with like denominators. - Allow students to ask any remaining questions or share any insights they gained during the lesson. - Assign homework that reinforces the concepts learned in class, such as additional fraction problems or real-life fraction scenarios.

Assessment: - Observe students’ participation and engagement during class activities. - Review students’ completed worksheets to assess their understanding of comparing and ordering fractions, as well as adding and subtracting fractions with like denominators. - Use questioning techniques during class discussions to gauge students’ comprehension of the lesson objectives.
