Linear vs. Non‑Linear Functions sorting activity for 8th grade Math students analyze tables, graphs, sequences, and equations.

Help your students master the difference between linear and non‑linear functions with this engaging Collaborative Sorting Task. Designed for 8th grade Math, this resource strengthens conceptual understanding by having students compare tables, graphs, sequences, and equations to determine whether each representation is linear or non‑linear.

Students justify their reasoning, discuss patterns, and build deep understanding across multiple representations—perfect for math talks, partner work, small groups, or independent practice.

What’s Included:

✔️ Linear & Non‑Linear Example Cards

✔️ Multiple representations: tables, graphs, sequences, equations

✔️ Student recording sheets

✔️ Answer keys

✔️ Teaching notes & instructional suggestions

✔️ Blank templates for students to create their own examples

Skills Students Practice:

• Identifying linear vs. non‑linear functions
• Recognizing constant rate of change
• Analyzing patterns in tables and sequences
• Interpreting graphs for linearity
• Classifying equations using structure

Perfect For:

• Collaborative learning
• Guided practice
• Intervention & reteaching
• Warm‑ups or math talks
• Formative assessment
• Homework or independent practice

Why Teachers Love It

This task makes abstract concepts visual and accessible. Students compare representations side‑by‑side, discuss their thinking, and build confidence with functions—an essential 8th grade standard.
