Key Concepts

  • Data Representation
  • Line Plots
  • Data Interpretation

Learning Objectives

  • Students will be able to create a line plot from a given set of data.
  • Students will be able to interpret a line plot and answer questions about the data.

Educator Instructions

  • Introduction (5 mins)
    Start by asking students if they have ever made a list or chart to organize information. Explain that today they will learn a new way to organize information called a line plot.
  • Watch the Video (7 mins)
    Play the Khan Academy video 'Introduction to line plots | Measurement and data | Early Math | Khan Academy'. Encourage students to pay attention to how the line plot is created and how it's used to answer questions.
  • Creating Our Own Line Plot (10 mins)
    Provide students with a simple data set, like the number of siblings each student in the class has (0, 1, 2, or 3). Guide them step-by-step in creating a line plot on a whiteboard or paper. Make sure they label the categories and use dots or X's to represent each student.
  • Answering Questions (8 mins)
    Once the line plot is created, ask questions about the data, such as: * 'How many students have 1 sibling?' * 'What is the most common number of siblings?' * 'How many students have more than 2 siblings?'
  • Wrap-up (5 mins)
    Review the key concepts of line plots and data representation. Emphasize how line plots make it easier to see and understand information.

Interactive Exercises

  • Classroom Survey Line Plot
    Conduct a quick survey in the classroom (e.g., favorite color, favorite animal). Have students create a line plot based on the survey results.
  • Line Plot Puzzles
    Give students pre-made line plots and ask them to create a data set that could match the line plot. This encourages reverse thinking and deeper understanding.

Discussion Questions

  • What is a line plot used for?
  • How can a line plot help us understand information better?

Skills Developed

  • Data Analysis
  • Problem-Solving
