Lesson Plan: Turning Mixed Numbers into Improper Fractions

Subject: Mathematics

Grade: 4

Duration: 30 Minutes

Topic: Turning Mixed Numbers into Improper Fractions

---

Lesson Objectives

By the end of the lesson, students will be able to:

1. Understand the concept of mixed numbers and improper fractions.
2. Convert mixed numbers into improper fractions using a step-by-step method.
3. Apply their understanding of improper fractions in problem-solving.

---

Materials Needed

• Whiteboard and markers
• Student workbooks
• Fraction circles (if available)
• Worksheets with practice problems
• Homework handouts

---

Introduction (5 Minutes)

1. Begin the lesson by asking students what they know about fractions.
2. Introduce mixed numbers as a combination of a whole number and a proper fraction (e.g., 2 1/3).
3. Explain that an improper fraction has a numerator that is greater than or equal to the denominator (e.g., 7/4).

Direct Instruction (10 Minutes)

1. Define Mixed Numbers:

   • A mixed number consists of a whole number and a fraction.
   • Example: 3 1/2 means three whole parts plus one-half.

2. Define Improper Fractions:

   • An improper fraction has a numerator larger than the denominator.
   • Example: 7/4 is improper because the numerator (7) is larger than the denominator (4).

3. Conversion Steps:
   To convert a mixed number into an improper fraction, follow these steps:

   • Multiply the whole number by the denominator of the fractional part:
   • (Whole Number × Denominator) + Numerator = New Numerator
   • Place this new numerator over the original denominator.

   Example: Convert 2 3/5 to an improper fraction.

   • Whole Number: 2
   • Fraction: 3/5
   • Calculation: (2 × 5) + 3 = 10 + 3 = 13
   • The improper fraction is 13/5.

---

Guided Practice (10 Minutes)

1. Write a mixed number on the board: 1 2/3.
2. Walk the students through the conversion step-by-step:
   • Multiply the whole number (1) by the denominator (3) → 1 × 3 = 3
   • Add the numerator (2) → 3 + 2 = 5
   • Therefore, 1 2/3 = 5/3.
3. Ask the students to try converting 3 1/4 into an improper fraction using the same steps.
   • Whole number: 3
   • Fraction: 1/4
   • Calculation: (3 × 4) + 1 = 12 + 1 = 13
   • Answer: 3 1/4 = 13/4

---

Independent Practice (5 Minutes)

1. Provide students with worksheets containing the following mixed numbers to convert to improper fractions:
   • 2 1/2
   • 4 3/10
   • 5 5/6
2. Monitor student progress and provide assistance as needed.

---

Conclusion (5 Minutes)

1. Review the key points of the lesson regarding mixed numbers and improper fractions.
2. Ask if there are any questions about the conversion process.
3. Reinforce that understanding how to convert mixed numbers is essential for further learning in fractions.

Homework

Assignment:

Convert the following mixed numbers into improper fractions:

1. 3 2/5
2. 1 3/8
3. 6 1/2
4. 4 4/7

Answer Key:

1. 3 2/5 = 17/5
2. 1 3/8 = 11/8
3. 6 1/2 = 13/2
4. 4 4/7 = 32/7
