Technology-Enhanced Item Graph PlotterWe’ve decided to kickoff our Technology Enhanced Items Showcase with an essential question type that serves as a stellar introduction to the interactive features of next generation assessments. Introducing Graph Plotter!

As simple as this question type is—it enables students to practice a deeper, more meaningful, level of interaction with graphs. Graph Plotter questions also give students the opportunity to demonstrate some of the problem solving skills the Common Core State Standards assess.   

Quick tip: When crafting questions with our items you want to mirror the features and concepts of the new online testing experience—making your assessments a surefire way of introducing blended learning models to your students on a daily basis.

Overview

TEI Graph Plotter

Standards & Learning Objectives Covered

| 7.RP – Ratios & Proportional Relationships | 7.RP.A.2 – Analyzing and identifying proportional relationships |

Ratios & Proportional Relationships

Analyze proportional relationships and use them to solve real-world and mathematical problems.

CCSS.MATH.CONTENT.7.RP.A.2

Recognize and represent proportional relationships between quantities.

What You Want Students To Do

Answer a question by creating, manipulating, or drawing on an online graph. Compare quantities in data and demonstrate a understanding of ratios.

Pedagogical Value

Tests students’ math, graphing, and data visualization skills. No guessing. Highly interactive. Students have to identify and explain proportional relationships. Gives instructors insights into how they’re using problem solving to contextualize mathematical relationships.

Notes

Used in Reading & Mathematics Assessments. Student drags bars on the graph to the correct value positions on the y-axis. Teacher sets x and y axes, along with the starting values for the bar chart. Grading = auto-scoring.

Creating a Graph Plotter Question

Below I’ll cover step-by-step how you can create a Graph Plotter question to add to your technology-enhanced assessments. *Click each image for an enlarged view.

The question featured in the following example:

A recipe requires the following ingredients to make 16 gingerbread men:

  • Flour: 100 grams
  • Sugar: 60 grams
  • Butter: 50 grams
  • Ginger: 20 grams

Cecily wants to make 24 gingerbread men. Use the following graph to indicate how much of each ingredient she will need: 

Step 1

Step 2

From your dashboard click on the main menu button to access Assessment. From there, click on + New Assessment and then Create New Assessment.

Make sure you have the correct subject and grade level—and then select the standard you’d like to assign. 

Step 3

Step 4

Click Create and then choose Graph Plotter from the TEI and interactive question types list.

Use the text editor to customize your question.

  • Start by adding your text-based question
  • Choose the table insert option in Text Editor, or other important features like insert image or equation

Step 5

Step 6

Modify Labels, Scale, and Categories

  • Give the x- and y-axis their appropriate titles
  • Modify y-axis scale to incorporate the highest value(s)
  • Add or subtract your x-axis categories and label them
  • Drag each x-axis bar to its correct answer on the graph

Modify the Starting Values & Optional Categories

  • Drag each x-axis bar to the value you’d like the students to see when they start the assessment, or you can leave them at the default
  • Choose to enter a solution or hint 
  • Modify the question difficulty level
  • Tag other learning objectives depending on how you craft the question 

Step 7

Click Save and then Review to make sure your question is correct before assigning it to your class.
