Lesson Plan: Adding Fractions

Grade Level: 6
Subject: Mathematics
Topic: Adding Fractions
Duration: 30 minutes

Objective

By the end of this lesson, students will be able to add fractions with like and unlike denominators.

Materials Needed

Introduction (5 minutes)

  1. Warm-up Activity: Start with a quick review of fractions. Ask students to define fractions and provide examples of already named fractions.
  2. Objective Overview: Explain the goal of the lesson: to learn how to add fractions. Pose the question, “What do we do when we need to add different pieces of a pie?” to engage students.

Instruction (15 minutes)

Adding Fractions with Like Denominators

  1. Definition: Explain that fractions with like denominators can be added by simply adding their numerators while keeping the denominator the same.
  2. Example:
    • ( \frac{2}{5} + \frac{1}{5} = \frac{2 + 1}{5} = \frac{3}{5} )
  3. Demonstration: Solve a couple more examples on the board with the class.

Adding Fractions with Unlike Denominators

  1. Finding a Common Denominator: Explain the process of finding a common denominator.
  2. Example:
    • To add ( \frac{1}{4} + \frac{1}{6} ):
      • Find the least common denominator (LCD) which is 12.
      • Convert fractions: ( \frac{1}{4} = \frac{3}{12} ) and ( \frac{1}{6} = \frac{2}{12} )
      • Now add: ( \frac{3}{12} + \frac{2}{12} = \frac{5}{12} )
  3. Practice Problem: Have students convert another set of fractions and solve together.

Guided Practice (5 minutes)

  1. Hand out worksheets with a variety of problems including both like and unlike denominators.
  2. Walk around to assist and ensure understanding.
  3. Example worksheet problems:
    • Add ( \frac{2}{3} + \frac{1}{3} )
    • Add ( \frac{1}{2} + \frac{1}{4} )

Independent Practice (5 minutes)

  1. Students will complete the remaining problems on the worksheet independently.
  2. Encourage students to show their work step-by-step.

Conclusion (5 minutes)

  1. Review key points of adding fractions. Reinforce which steps to take for like and unlike denominators.
  2. Ask students questions to recap their understanding of the lesson objectives.

Homework

Complete the following tasks:

  1. Add the following fractions:

    • ( \frac{5}{8} + \frac{3}{8} )
    • ( \frac{2}{5} + \frac{1}{10} )
    • ( \frac{7}{12} + \frac{1}{4} )
  2. Explain in one or two sentences how to find a common denominator.

Homework Answers

  1. ( \frac{5}{8} + \frac{3}{8} = \frac{8}{8} = 1 )
  2. ( \frac{2}{5} + \frac{1}{10} = \frac{4}{10} + \frac{1}{10} = \frac{5}{10} = \frac{1}{2} )
  3. ( \frac{7}{12} + \frac{1}{4} = \frac{7}{12} + \frac{3}{12} = \frac{10}{12} = \frac{5}{6} )
  4. Students should mention finding the least common multiple or the method of cross-multiplying denominators to find a common denominator.

Assessment

Evaluate students based on their participation in guided practice, completion of independent practice, and accuracy in homework.

Let’s add fractions with confidence!
