Lesson Title: Exploring Equivalent Fractions with Related Denominators

Grade Level: Year 4

Objective: Students will be able to represent the equivalence of fractions with related denominators as lengths using concrete materials, diagrams, and number lines.

Materials: - Fraction strips (concrete materials) - Whiteboard or chart paper - Markers - Rulers - Colored pencils or crayons - Worksheets with fraction diagrams and number lines (optional)

Procedure:

1. Introduction (5 minutes):
   • Begin the lesson by asking students if they remember what fractions are and how they are represented.
   • Review the concept of fractions briefly, emphasizing the numerator and denominator.
   • Explain that today, they will be learning about equivalent fractions with related denominators and how to represent them using different tools.
2. Concrete Materials (10 minutes):
   • Distribute fraction strips to each student or group of students.
   • Instruct students to fold the fraction strip in half to represent the fraction 1/2.
   • Ask students to explore and find other fractions that are equivalent to 1/2 by folding the strip into different parts.
   • Encourage students to discuss their findings with their peers and record their observations on the whiteboard or chart paper.
3. Diagrams (15 minutes):
   • Provide each student with a worksheet containing fraction diagrams.
   • Instruct students to shade the fraction diagrams to represent the given fractions.
   • Start with simple fractions such as 1/2, 1/3, and 1/4, and gradually increase the complexity.
   • Encourage students to compare and discuss their diagrams with their peers, noting any similarities or differences.
4. Number Lines (15 minutes):
   • Introduce the concept of representing fractions on a number line.
   • Draw a number line on the whiteboard or chart paper, labeling the endpoints as 0 and 1.
   • Ask students to mark the fractions they have explored earlier on the number line.
   • Discuss with the class how the fractions with related denominators are located at equal intervals on the number line.
   • Encourage students to explain their reasoning and observations.
5. Consolidation (5 minutes):
   • Review the main concepts covered in the lesson, emphasizing the representation of equivalent fractions with related denominators using concrete materials, diagrams, and number lines.
   • Ask students to share any new insights or connections they have made during the lesson.
   • Provide feedback and address any misconceptions or questions.
6. Extension Activity (optional):
   • Distribute worksheets with fraction diagrams and number lines.
   • Instruct students to complete the worksheets independently, representing different equivalent fractions with related denominators.
   • Collect and review the completed worksheets to assess students’ understanding.

Note: The duration of each activity can be adjusted based on the pace and needs of the students.
