Interpret Qualitative Graphs of Real Situations
Written by Adi Ackerman, Head Teacher
"Interpret Qualitative Graphs of Real Situations" is written for 8th Grade (Ages 13-14), and it covers Common Core 8.F.B.5. A 7th grader who is already steady on functions can use it too, and an older student can use it as a short review.
8th grade math worksheet: label parts of graphs for a bus, a tub and a swing as increasing, decreasing or constant. Answer key included. Part of our qualitative graphs functions collection. Aligned to Common Core standards.
How do I use this worksheet?
Start with the labeling sheet, then the matching sheet. Finish with sketching and writing, which work well as partner tasks.
What students will practice
- Students will mark each part of a graph as increasing, decreasing or constant.
- Students will match sentences, such as the bus is stopped, to parts of a graph.
- Students will read graphs that have no numbers on the axes.

Functions · 8th Grade
Standard: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

FAQ
How do I use this qualitative graphs worksheet?
⌄
Start with the labeling sheet, then the matching sheet. Finish with sketching and writing, which work well as partner tasks.
What does this worksheet teach?
⌄
Label parts of graphs for a bus, a tub and a swing as increasing, decreasing or constant. The directions on the page read: In the row of boxes, write I if the graph is increasing in that part, D if it is decreasing and C if it is constant. Then write the letter of the part that matches each sentence. An answer key is included.
Can I use this qualitative graphs worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 8th grade functions, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What does a flat part of a distance graph mean?
⌄
The distance is not changing, so the person has stopped. Match Stories to Qualitative Graphs uses this when Ravi shops for a while before walking home.
How do you show speeding up on a qualitative graph?
⌄
The graph gets steeper as it goes. A part that gets flatter shows slowing down, and a straight part shows a steady rate.
How do you sketch a graph from a story?
⌄
Break the story into parts and decide whether the quantity rises, falls or stays level in each one. Sketch a Graph From a Story asks students to show this without numbers.
