Lesson Plan

Graphing a Story

Students will be able to sketch a graph that reflects the key features of a given real-world narrative or event.

This lesson helps students translate real-world narratives into mathematical graphs, specifically focusing on time-distance relationships. It's crucial for developing analytical skills and understanding how data can tell a story.

Audience

9th Grade

Time

65 minutes

Approach

Students will explore narrative examples, analyze key events, and translate them into graphical representations.

Prep

Teacher Preparation

15 minutes

Step 1

Introduction & Hook: What's Your Story's Graph?

10 minutes

  • Engage: Begin by asking students: "Can a story be drawn as a graph?" Project an intriguing image or a simple narrative (e.g., a person walking to a store, stopping, and returning home).
    * Discuss: Facilitate a brief discussion about how movement or change over time could be represented visually. Introduce the idea of time-distance graphs. (Refer to Graphing a Story Slide Deck - Slides 1-3)

Step 2

Direct Instruction: Graphing the Narrative

15 minutes

  • Explain: Use the Graphing a Story Slide Deck (Slides 4-8) to explain key concepts: variables (time, distance), axes, and how different actions (constant speed, stopping, changing direction) translate into parts of a graph.
    * Model: Present a simple narrative and model how to sketch its corresponding time-distance graph step-by-step on the board, emphasizing identifying key events and changes. (Refer to Graphing a Story Narrative Handout - Example 1)

Step 3

Guided Practice: Sketching Together

15 minutes

Step 4

Independent Practice: Your Turn to Graph

15 minutes

  • Application: Students will independently work on the remaining narratives on the Graphing a Story Worksheet, sketching graphs for each. Circulate to provide support and answer questions. Encourage peer discussion. (Refer to Graphing a Story Worksheet - Questions 2-3)

Step 5

Wrap-up & Assessment: Share & Reflect

10 minutes

  • Share: Have students share and compare their graphs for one of the independent practice narratives, explaining their choices. Project the correct graph if needed.
    * Assess: Distribute the Exit Ticket: Graphing a Story Quiz for individual completion to gauge understanding. Collect it before students leave.
    * Introduce Project: Briefly introduce the Create-a-Graph Story Project Guide and explain that students will be using the Peer Feedback Rubric for an upcoming activity.

Slide Deck

Can a Story Be Drawn as a Graph?

What do stories and graphs have in common?

Think about:

  • A journey to school
  • A growing plant
  • A rising and falling temperature

How can we visually represent changes over time?

Welcome students and introduce the intriguing question for today's lesson. Encourage initial thoughts and predictions. This sets the stage for thinking about how stories and data connect.

Let's Tell a Visual Story!

Narrative:
A person leaves their house, walks to a friend's house, stops to chat for a while, and then walks back home at a slightly faster pace.

How could we show this journey without words, using lines and points?

Focus on a simple narrative to get students thinking visually about changes in position over time. Ask questions like: 'What's happening at each point?' and 'How would you show stopping?'

Introducing Time-Distance Graphs

Time-distance graphs help us visualize motion and position over a period of time.

  • X-axis: Represents Time
  • Y-axis: Represents Distance from a starting point

What kind of 'story' can these graphs tell?

Introduce the concept of a time-distance graph as a tool for storytelling. Emphasize that we're looking at patterns of movement. Set the stage for direct instruction.

Key Concepts: Variables & Axes

To graph a story, we need to understand a few things:

  • Variables: What changes in our story?
    • Time (x-axis): How much time has passed.
    • Distance (y-axis): How far away something is from a specific starting point.
  • Origin (0,0): This is usually your starting point or 'home.'
  • Units: Always remember to label your axes with appropriate units (e.g., minutes, meters).

Explain the importance of variables and how they relate to the axes. Clarify 'distance from start' as the y-axis measure.

Different Movements, Different Lines

The way a line looks on a time-distance graph tells us about the motion:

  • Horizontal Line: No change in distance over time. What does this mean?
    • Think: Standing still!
  • Slanted Line (upwards): Distance is increasing over time. What does this mean?
    • Think: Moving away from the start!
  • Slanted Line (downwards): Distance is decreasing over time. What does this mean?
    • Think: Moving back towards the start!

Discuss how different types of movement translate to different slopes or lines on a graph. Use simple, clear examples.

Speed and Steepness

The steepness (or slope) of the line tells us about the speed.

  • Steeper Line: Faster speed.
  • Less Steep Line: Slower speed.
  • Straight Line: Constant speed (not speeding up or slowing down).
  • Curved Line: Changing speed (speeding up or slowing down).

Elaborate on speed and how it's represented by the steepness of the line. Connect 'steeper' to 'faster.'

Story Features & Graph Features

Match the story action to the graph feature:

  • Starting Point: Origin (0,0)
  • Moving Away: Line going up
  • Moving Towards: Line going down
  • Stopping/Resting: Flat, horizontal line
  • Faster Speed: Steeper line
  • Slower Speed: Less steep line

Summarize the key connections between narrative elements and graphical features. This is a good slide for students to internalize the relationships.

Ready to Graph a Story?

When you read a narrative, look for:

  1. Starting Point: Where does the story begin?
  2. Key Events: What happens? (Movement, stops, changes in direction/speed)
  3. Order of Events: What happens first, next, last?
  4. Distance Changes: Is the distance from the start increasing or decreasing?
  5. Time Elapsed: How much time passes during each event?

Let's try one together!

Transition into guided practice. Remind students of the steps to take when analyzing a narrative to graph it.

Reading

Graphing a Story Narrative Handout

Read the following narratives carefully. You will use these stories to practice sketching graphs that represent the movement described.


Example 1 (For Direct Instruction)

The Morning Commute

Maria leaves her house and walks at a steady pace to the bus stop, which is 500 meters away. She waits for the bus for 5 minutes. The bus arrives and quickly takes her to school, which is 2000 meters from her house, much faster than she walks. After school, she takes the bus directly home.

Key Events to Consider:

  1. Leaving house, walking to bus stop.
  2. Waiting at the bus stop.
  3. Bus ride to school.
  4. Bus ride home from school.

Example 2 (For Guided Practice)

The Jogger's Journey

A jogger starts from their home and runs at a constant speed for 10 minutes, covering a distance of 1.5 kilometers. They then stop for a 5-minute water break. After the break, they jog back towards home, but at a slightly slower constant speed, until they reach their home.

Key Events to Consider:

  1. Running away from home.
  2. Stopping for a water break.
  3. Running back home at a slower speed.

Worksheet

Graphing a Story Worksheet

Instructions: For each narrative below, sketch a time-distance graph that accurately represents the story. Label your axes (Time and Distance from Start) and include approximate units (e.g., minutes, meters). Pay attention to changes in speed, stops, and direction.


Question 1: The Jogger's Journey (Guided Practice)

Recall the narrative from the Handout: A jogger starts from their home and runs at a constant speed for 10 minutes, covering a distance of 1.5 kilometers. They then stop for a 5-minute water break. After the break, they jog back towards home, but at a slightly slower constant speed, until they reach their home.

Sketch your graph here:













Explain your graph choices for the jogger's journey:








Question 2: The Delivery Driver

A delivery driver starts from the depot and drives 3 miles to the first house in 6 minutes. They spend 2 minutes at the first house. Then, they drive another 2 miles to the second house in 3 minutes. After delivering the package, they drive directly back to the depot, covering 5 miles in 8 minutes.

Sketch your graph here:













Explain your graph choices for the delivery driver:








Question 3: The Rollercoaster Ride

A rollercoaster starts at the base of the first hill, slowly climbs to the top for 30 seconds, reaching a height equivalent to being 100 feet from the starting horizontal point. It then plunges down the hill very quickly for 5 seconds. After a brief, flat section for 10 seconds, it slowly climbs another smaller hill for 20 seconds, reaching 70 feet from the start, before smoothly descending back to the starting point in 15 seconds.

Sketch your graph here:













Explain your graph choices for the rollercoaster ride:

Project Guide

Create-a-Graph Story Project Guide

Project Goal

Your task is to create your own real-world narrative and a corresponding time-distance graph that accurately reflects the events in your story. You will then present your story and graph to a small group of classmates for peer feedback.

Project Components

  1. Original Narrative (Written):

    • Write a short, clear story (5-8 sentences) about a journey or movement.
    • Your narrative should include at least four distinct phases of movement:
      • Moving away from a starting point at a constant speed.
      • Stopping/resting for a period of time.
      • Moving back towards the starting point at a constant speed.
      • A change in speed (either speeding up or slowing down, or moving faster/slower than another segment).
    • Be creative! You can write about a person, an animal, a vehicle, or even an object (e.g., a drone delivering a package).
    • Do not include the graph in your written narrative. Your classmates will try to graph it!
  2. Time-Distance Graph (Drawn):

    • On a separate piece of graph paper, draw a time-distance graph that precisely matches your narrative.
    • Label your axes: Make sure to clearly indicate "Time" on the x-axis and "Distance from Start" on the y-axis.
    • Include units: Use appropriate units for both time (e.g., seconds, minutes) and distance (e.g., meters, blocks, miles).
    • Accurately represent:
      • Your starting point.
      • Periods of movement away from and towards the start.
      • Periods of no movement (stops).
      • Changes in speed (represented by the steepness of the line).
      • Any changes in direction.
    • This graph will be your answer key for your narrative.

Presentation & Peer Feedback

  1. You will work in small groups. When it's your turn, read your narrative aloud to your group members.
  2. Your group members will listen to your story and attempt to sketch a time-distance graph based on your narrative on a blank piece of paper.
  3. After they have completed their sketches, you will reveal your own graph. Discuss the similarities and differences, and explain your choices.
  4. Your group members will then use the Peer Feedback Rubric to provide constructive feedback on your narrative and their interpretation of it. You will also provide feedback to your peers.
