Cladograms Reading Comprehension and Worksheets

This cladograms reading comprehension is a clear and approachable way to help high school biology students understand how to read and interpret cladograms, identify common ancestors, and use shared derived characteristics to compare evolutionary relationships.

Perfect for high school biology students, this cladograms activity uses scaffolded reading support, helpful diagrams, text-dependent questions, vocabulary practice, a CER worksheet, and an interpreting and drawing cladograms activity to guide students through the key ideas.

This cladograms lesson includes two versions (guided and traditional) with the same content and same questions. Also included is are 2 bonus practice worksheets you can use as extra practice, homework, sub plans, or quiz review.

Cladograms Comprehension Package Includes:

• Cladograms Guided Reading: This 4-page guided reading is chunked into sections, with questions placed between each subtopic of information. This format has many benefits because it allows students to focus on one topic at a time, reflect on what they’ve read, and answer questions as they progress.

• Traditional Cladograms Reading Comprehension: This 3-page cladograms reading comprehension follows a traditional format, with the content presented first and the questions provided on a separate sheet to be completed afterward. Two versions of the questions are included: a 2-page handout where students can write directly on the sheets, and a 1-page question list that prompts students to write their answers on a separate sheet of paper.

• 2 Bonus Cladograms Worksheets: Two text-dependent worksheets are included for extra practice. They include a cladograms CER activity, vocabulary matching, and an interpreting and drawing diagrams practice worksheet.

• Answer Keys: Answer keys are included for all questions.

• Digital and Print: PDF and Google Slides versions for all activities

This is a perfect student-led cladograms lesson! All questions are text-dependent and do not require prior knowledge. Students will learn how to identify nodes, roots, clades, taxa, common ancestors, and shared derived characteristics. They will also practice using trait tables, interpreting branching diagrams, building cladograms, and supporting claims with evidence from a cladogram.
