Lesson Title:Adding and Subtracting Fractions

Lesson Objective: Students will be able to add and subtract fractions with confidence and accuracy.

Materials:

  • Whiteboard and markers
  • Fraction worksheets
  • Manipulatives (fraction circles, fraction bars, etc.)
  • Calculator

    • Introduction (5 minutes):

  • Begin by reviewing the concept of fractions and their parts (numerator and denominator).
  • Write the fraction “3/4” on the board and ask students to identify the numerator and denominator.
  • Introduce the concept of adding and subtracting fractions and why it is important.

    • Direct Instruction (20 minutes):

  • Provide students with manipulatives and have them create fractions.
  • Have students practice adding and subtracting fractions using the manipulatives.
  • As they work, circulate the room and provide individual assistance as needed.
  • Introduce the process of finding the least common denominator (LCD) when adding and subtracting fractions with different denominators.

    • Guided Practice (20 minutes):

  • Provide students with fraction worksheets and have them complete a set of problems together as a class.
  • Go over the answers together, discussing any misconceptions or difficulties that students may have had.
  • Have students practice finding the LCD when adding and subtracting fractions with different denominators using the calculator.

    • Independent Practice (20 minutes):

  • Give students additional fraction worksheets to complete on their own.
  • Encourage students to check their work and ask for assistance if needed.
  • Provide students with a real-life scenario where they have to add and subtract fractions, for example, calculating the cost of buying different fruits.

    • Closure (5 minutes):

  • Review the key concepts covered in the lesson, such as the process of adding and subtracting fractions, finding the LCD, and why it is important.
  • Give students an opportunity to share any strategies or tips they found helpful during the lesson.
  • Preview the next lesson and the related homework.

    • Assessment:

  • Observe students during independent practice to assess their understanding of the concepts taught during the lesson.
  • Collect and review completed worksheets as a form of summative assessment.
  • Observe students during their real-life scenario activity and assess their ability to add and subtract fractions correctly.

    • Note: The above plan is a general outline and may need to be adapted depending on the specific needs and capabilities of the students in your class.
