Key Concepts

  • Fraction
  • Numerator
  • Denominator
  • Greatest Common Factor (GCF)
  • Simplest Form (Lowest Terms)
  • Equivalent Fractions

Learning Objectives

  • Students will be able to define numerator and denominator.
  • Students will be able to define simplest form of a fraction.
  • Students will be able to identify the Greatest Common Factor (GCF) of two numbers.
  • Students will be able to simplify a fraction to its simplest form by dividing the numerator and denominator by their GCF.
  • Students will be able to recognize that simplest form and lowest terms are synonyms.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they know what a fraction is. Briefly review what a fraction is. Briefly discuss the video's backstory involving Godzilla and his quest to simplify fractions to grab the students' attention. Explain that today, they will learn how to simplify fractions.
  • Video Viewing (5 mins)
    Play the NUMBEROCK 'Simplest Form Song: Simplifying Fractions' video (https://www.youtube.com/watch?v=U-1KjlJAA6M). Encourage students to sing along and pay attention to the steps for simplifying fractions.
  • Concept Explanation (10 mins)
    After the video, discuss the key concepts. Define numerator and denominator, greatest common factor (GCF), and simplest form (lowest terms). Write examples of fractions on the board (e.g., 2/4, 4/12, 5/15). Explain the process of finding the GCF of the numerator and denominator. Show how dividing both by the GCF results in the simplest form.
  • Guided Practice (15 mins)
    Work through example problems together as a class. For example: Simplify 6/8. What are the factors of 6? (1, 2, 3, 6). What are the factors of 8? (1, 2, 4, 8). What is the GCF? (2). Divide both by 2. 6/8 = 3/4. Therefore, 3/4 is the simplest form. Repeat with other examples, inviting students to participate and explain each step.
  • Independent Practice (15 mins)
    Provide students with a worksheet or online activity with fraction simplification problems. Have them work independently. Circulate to provide assistance as needed.
  • Review and Closure (5 mins)
    Review the answers to the independent practice problems. Reiterate the steps for simplifying fractions. Ask students to summarize what they learned about fractions and simplifying them. Emphasize that fractions are happiest when they are in the simplest form, just like in the video.

Interactive Exercises

  • Fraction Simplification Race
    Divide the class into teams. Give each team a set of fraction cards. On your signal, teams race to simplify the fractions correctly. The first team to simplify all their fractions wins.
  • Simplest Form Bingo
    Create bingo cards with simplest form fractions. Call out unsimplified fractions. Students mark the corresponding simplest form on their bingo cards. The first student to get bingo wins.
