Key Concepts

  • Fair sharing means dividing something into equal parts.
  • Fractions represent parts of a whole.
  • Different fractions (halves, fourths, tenths) represent different divisions of the whole.

Learning Objectives

  • Students will be able to define fair sharing and explain its importance.
  • Students will be able to divide a whole object into equal parts (halves, fourths, and tenths).
  • Students will be able to identify and name fractions (halves, fourths, and tenths) that represent equal parts of a whole.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students about times they've had to share with others. Discuss what makes sharing 'fair'. Introduce the video and explain that it will teach them about sharing equally using fractions.
  • Video Viewing (7 mins)
    Play the "How to use Fractions to Show Equal Parts" video by Miacademy Learning Channel. Encourage students to pay attention to the examples of sharing cakes and jelly beans.
  • Discussion (8 mins)
    After the video, lead a class discussion using the discussion questions below. Focus on understanding the concept of 'fair share' and how it relates to dividing objects into equal parts.
  • Interactive Exercise: Cake Cutting (10 mins)
    Divide students into small groups and give each group a paper circle representing a cake. Provide different sharing scenarios (e.g., share the cake with 2 people, 4 people, 10 people). Have them cut the 'cake' into equal pieces to represent fair shares. Discuss the resulting fractions (halves, fourths, tenths).
  • Assessment (5 mins)
    Administer the multiple-choice and fill-in-the-blank quizzes to assess student understanding of the concepts.

Interactive Exercises

  • Cake Cutting
    Students divide a paper circle (representing a cake) into equal parts to simulate fair sharing scenarios. They then identify the fraction that represents each share.
  • Jelly Bean Sorting
    Provide students with a set of jelly beans or other small objects. Give them scenarios where they must divide the jelly beans equally between different numbers of people. This reinforces the concept of equal sharing with individual items.

Discussion Questions

  • What does it mean to share something fairly?
  • Why is it important for everyone to get an equal share?
  • Can you think of a time when you had to share something? Was it fair?
  • How does cutting a cake into equal pieces help us share it fairly?
  • What are some other things we can divide into equal parts?
