Key Concepts

  • Factors
  • Greatest Common Factor (GCF)
  • Equivalent Fractions
  • Simplest Form

Learning Objectives

  • Students will be able to identify factors of given numbers.
  • Students will be able to find the Greatest Common Factor (GCF) of two numbers.
  • Students will be able to simplify fractions to their lowest terms by dividing by the GCF.
  • Students will understand that simplifying a fraction does not change its value.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about fractions. Introduce the concept of simplifying fractions and explain that it means finding an equivalent fraction with smaller numbers. Show the 'Simplifying Fractions Step by Step' video by Math with Mr. J (https://www.youtube.com/watch?v=oFVzcnJfYkg).
  • Factors and GCF (10 mins)
    Review the concept of factors. Have students brainstorm factors for various numbers. Then, introduce the Greatest Common Factor (GCF). Work through examples of finding the GCF of two numbers, using the method shown in the video (listing factors).
  • Simplifying Fractions (15 mins)
    Explain that to simplify a fraction, you divide both the numerator and denominator by their GCF. Work through the examples from the video again, step-by-step, emphasizing the importance of dividing both parts of the fraction. Provide additional examples for students to practice simplifying. Remind them that you are not changing the value of the fraction, just making it simpler.
  • Practice and Application (15 mins)
    Provide students with a worksheet containing various fractions to simplify. Encourage them to work independently or in pairs. Circulate the room to provide support and answer questions. After they complete the worksheet, review the answers as a class.
  • Wrap-up (5 mins)
    Summarize the key concepts of the lesson: factors, GCF, and simplifying fractions. Emphasize the importance of simplifying fractions in later math concepts. Briefly discuss how simplifying fractions can be useful in real-life situations (e.g., sharing pizza, measuring ingredients).

Interactive Exercises

  • Fraction Simplification Game
    Play a game where students are given a fraction and must simplify it as quickly as possible. This can be done individually or in teams.
  • Online Fraction Simplifier
    Use an online fraction simplifier tool to check student work and demonstrate the simplification process. (e.g., https://www.mathpapa.com/simplify-fractions/)
