Lesson Title

Introduction to Fractions

Objectives

• Understand the concept of fractions as parts of a whole.
• Identify and create simple fractions with manipulatives.
• Compare and order fractions with like denominators.

Materials Needed

• Paper plates
• Scissors
• Markers
• Fraction strips (printed or drawn on paper)
• Whiteboard and markers

Standards Addressed

• CCSS.MATH.CONTENT.3.NF.A.1: Understand a fraction as a number on the number line; represent fractions on a number line diagram.
• CCSS.MATH.CONTENT.4.NF.A.1: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models.

Lesson Outline

Introduction (5 minutes)

• Begin with a brief discussion about what students know about fractions.
• Ask questions such as: "What do you think a fraction is?" and "Where do we see fractions in real life?"

Direct Instruction (10 minutes)

1. Define Fractions: Explain that fractions represent parts of a whole. Use visual aids and examples (e.g., pizza slices, pie charts).
2. Components of a Fraction: Illustrate the numerator and denominator using examples on the whiteboard.
3. Creating Fractions: Distribute paper plates and scissors. Instruct students to cut their plates into different fractions (halves, thirds, quarters).

Guided Practice (10 minutes)

• Using the fraction strips, ask the students to:
  • Create fractions using their strips.
  • Work in pairs to compare their fractions (e.g., 1/2 vs. 1/3) and decide which is larger or if they are equal.
• Encourage students to express their reasoning verbally.

Independent Practice (5 minutes)

• Hand out a worksheet with simple fraction problems, including:
  1. Identify the fraction for the shaded part of a rectangle.
  2. Compare two fractions (e.g., which is greater: 1/4 or 1/6?).
  3. Order a set of fractions (e.g., 1/3, 1/2, 1/4).

Conclusion (2 minutes)

• Wrap up by summarizing the key points about fractions.
• Encourage students to share one new thing they learned today.

Homework

Tasks

1. Draw a picture that represents 3/4 of an object (e.g., pizza).
2. Fill out the following comparisons:
   • Compare: 2/5 _____ 1/5
   • Compare: 3/8 _____ 1/2
3. Order the following fractions from least to greatest: 1/3, 1/6, 1/2.

Correct Answers

1. Drawings will vary but should accurately depict three-quarter portions of an object.
2. • 2/5 > 1/5 (greater than)
   • 3/8 < 1/2 (less than)
3. 1/6, 1/3, 1/2.

Assessment

• Review student understanding through their participation in discussions, the accuracy of the independent practice worksheet, and the completeness of their homework.

Reflection

• After the lesson, reflect on what went well and what could be improved for future sessions. Consider student engagement and understanding of fractions as concepts.
