8th Grade Analyzing Graphs Quizzes

Use a claim-evidence-reasoning routine. Students first identify a trend or relationship, cite coordinates or intervals as evidence, and then explain how the evidence supports a prediction or conclusion.

Prioritize tasks that ask students to identify trends, estimate or calculate rates of change, make predictions, and compare representations. Line graphs and scatter plots are especially useful for connecting visual patterns to relationships between variables.

Watch for students who ignore unequal scale intervals, calculate a rate of change using the wrong coordinate order, or extend a trend beyond what the data reasonably supports. Asking them to mark the two points used in a calculation makes many of these errors visible.

The quizzes can be hosted as digital quizzes on Wayground or distributed as printable PDFs. Each includes a complete answer key; for paper assignments, teachers can capture student work and grade it with the Wayground for Teachers app.

Common Core expects Grade 8 students to connect graphs with relationships between variables. Students progress from describing plotted data to interpreting rates of change, recognizing linear patterns, and using trends to make predictions, which supports later work with functions and statistics.

Use extended time for students who need longer to inspect scales and compute rates of change, or reduce answer choices when the interpretation load is too high. Alternate printable versions can use larger text and wider spacing to make labels and directions easier to process.

This collection is designed for Grade 8, when students increasingly connect graphical patterns to rates of change, relationships between variables, and evidence-based predictions.
