Lesson Plan: Addition and Subtraction of Mixed Numbers

Grade Level: 5

Duration: 30 Minutes

Subject: Mathematics

Topic: Addition and Subtraction of Mixed Numbers

Objectives

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

1. Understand how to add and subtract mixed numbers.
2. Simplify their answers when possible.
3. Apply their knowledge to solve real-world problems involving mixed numbers.

Materials Needed

• Whiteboard and markers
• Printed worksheets for practice activities
• Rulers
• Visual aids (fraction circles or bars)

Introduction (5 Minutes)

• Begin the lesson with a brief review of fractions and whole numbers.
• Explain that mixed numbers consist of a whole number and a fraction (e.g., 2 ½).
• Ask students for examples of mixed numbers they encounter in daily life (e.g., cooking measurements, distances).

Direct Instruction (10 Minutes)

1. Adding Mixed Numbers:

   • Demonstrate how to add mixed numbers with the same denominator.

     • Example: 2 ⅓ + 1 ⅓
       • Step 1: Add the whole numbers: 2 + 1 = 3
       • Step 2: Add the fractions: ⅓ + ⅓ = ⅔
       • Step 3: Combine: 3 + ⅔ = 3 ⅔

   • Next, show how to add mixed numbers with different denominators.

     • Example: 1 ½ + 2 ⅓
       • Step 1: Convert to an improper fraction: 1 ½ = 3/2 and 2 ⅓ = 7/3
       • Step 2: Find a common denominator (6):
         • 3/2 becomes 9/6
         • 7/3 becomes 14/6
       • Step 3: Add: 9/6 + 14/6 = 23/6
       • Step 4: Convert back to a mixed number: 3 ⅔

2. Subtracting Mixed Numbers:

   • Demonstrate subtracting mixed numbers, similar to the addition process.
     • Example: 3 ¾ - 1 ⅔
       • Step 1: Convert to improper fractions: 3 ¾ = 15/4 and 1 ⅔ = 5/3
       • Step 2: Find a common denominator (12):
         • 15/4 becomes 45/12
         • 5/3 becomes 20/12
       • Step 3: Subtract: 45/12 - 20/12 = 25/12
       • Step 4: Convert to mixed number: 2 1/12

Guided Practice (10 Minutes)

• Provide students with a worksheet that includes several mixed number addition and subtraction problems.

• Examples:

  1. 2 ½ + 1 ⅔
  2. 4 ⅖ - 2 ¼
  3. 3 ⅗ + 2 ¾
  4. 5 - 2 ⅖

• Circulate around the room assisting students as needed and encouraging them to explain their thought process.

Independent Practice (5 Minutes)

• Allow students to complete a few more problems on their own:

  1. 6 ⅓ + 2 ⅘
  2. 7 ½ - 4 ⅓

• Collect their answers for assessment.

Closing (2 Minutes)

• Review the key steps in adding and subtracting mixed numbers.
• Highlight the importance of simplifying the final answers.

Homework

Assign students the following problems related to the day’s lesson:

Homework Problems:

1. 1 ¾ + 2 ⅗
2. 3 ⅖ - 1 ⅘
3. 4 ⅔ + 2 ¼
4. 5 ⅗ - 3 ⅖

Homework Answers:

1. 1 ¾ + 2 ⅗ = 4 1/10
2. 3 ⅖ - 1 ⅘ = 1 ⅗
3. 4 ⅔ + 2 ¼ = 6 ⅔
4. 5 ⅗ - 3 ⅖ = 2

Assessment

• Monitor student performance during guided practice.
• Review homework to assess understanding and identify areas needing reinforcement.

Accommodation

• For students needing additional help, provide one-on-one support.
• Provide visual aids or fraction manipulative tools to help with understanding fractions.

This lesson should effectively engage Grade 5 students with the topic of addition and subtraction of mixed numbers, promoting both comprehension and application skills.
