Compare and contrast charts have sections for the two ideas' shared common traits or similarities. If you are using a Venn diagram, write the shared details in the area where the circles intersect. In the column-style diagram, as shown in the below compare and contrast chart, write these details in the shared rectangle you drew near the chart's top. It should be noted here that comparing and contrasting activities use critical thinking skills to recognize similarities and differences in two ideas. A graphic organizer helps students sort out the details as they compare and contrast. The following compare and contrast organization chart is created using EdrawMax Online and shows two different items under two different columns, representing the images, differences, and similarities.
