Why is This Skill Important?
Teaching similarities and differences are essential for students in grades 4-12. This skill is crucial because it helps students develop critical thinking and analytical skills necessary for academic success and lifelong learning. If you have read Marzano’s research in his book, Classrooms That Work, you know that helping students identify similarities and differences is considered a “high yield” strategy. It is an essential skill for teaching content and helping students improve academic performance in all content areas.
How to Teach Similarities and Differences with Graphic Organizers
One effective way to teach similarities and differences is by using graphic organizers. Graphic organizers are visual tools that help students organize and synthesize information. They provide a framework for students to compare and contrast different concepts and ideas. You use this technique with literature, for example, by asking students to write about how two stories connect. Students should describe all the ways the two stories are similar and how they are different. Provide a graphic organizer to help students organize their information before writing their papers.
Many graphic organizers can be used to teach similarities and differences. One common type is the Venn diagram. Venn diagrams are circles that overlap to show the similarities and differences between two or more items. They are an excellent tool for comparing and contrasting different concepts and ideas.
Another type of graphic organizer that can be used to teach similarities and differences is the T-chart. T-charts are charts with two columns, one for similarities and one for differences. They are a simple yet effective tool for organizing information and identifying similarities and differences between concepts or ideas.
Using Real World Examples to Deepen Thinking Skills
In addition to using graphic organizers, teachers can also use real-world examples to teach similarities and differences. For example, teachers can ask students to compare and contrast different types of food or different countries. This approach helps students understand the practical applications of similarities and differences and makes the topic more relatable and engaging.

Teaching Similarities and Differences Through Text
Another effective way to teach similarities and differences is with text. Teachers can use books and stories to teach students how to compare and contrast different characters, settings, and plot points.
In content areas, teachers can use two or more informational articles to help students understand how different authors might have different perspectives or viewpoints on a topic. This approach helps students develop critical thinking skills and helps them see the importance of reading to build knowledge.
Teachers can create activities that require students to compare and contrast different concepts and ideas. For example, teachers in younger grades might ask students to create a Venn diagram comparing and contrasting two different animals. Teachers in middle or high school might use this skill to complete a T-chart comparing two different types of technology, a scientific process or the perspectives of two or more versions of a historical event.
Another effective activity for teaching similarities and differences is a gallery walk. Gallery walks involve displaying different objects or images around the classroom and asking students to compare and contrast them. This activity encourages students to think critically and analyze information from different perspectives.
Using Similarities and Differences to Deepen Thinking Skills
Since teaching similarities and differences are essential for students in grades 4-8, including these strategies in your teaching is essential. A critical aspect of teaching similarities and differences is to provide students with opportunities to practice the skill. Understanding how to compare and contrast concepts helps students develop critical thinking and analytical skills. Both of these skills are essential for academic success and lifelong learning. By using graphic organizers, real-world examples, literature, and engaging activities, teachers can help students master this skill and become confident, competent learners.
