A compare/contrast or Venn diagram is used to
identify the similarities and differences between
two or more concepts. The most commonly used
organizer, this instructional tool is found in
textbooks, on standardized tests, and in teacher
resource materials.

Cause-and-Effect Diagram
A cause-and-effect diagram highlights the direct
relationship between different events or concepts.
This tool is one of the most beneficial organizers
because of its many applications in all subject
areas.
For example, this diagram might be used to
analyze characters and events in reading, to
discuss major events in social studies, or to study
the impact of a science experiment.
Causes Effects
Main Idea and Details Chart
A main idea and details chart shows the
hierarchical relationship between major concepts
and their subordinate elements. This organizer is
extremely beneficial in helping students
distinguish central ideas and their corresponding
details from less important information.
When using the type of graphic organizer, clearly
label the main idea and the details as such. Use a
different shape or area for the main idea and the
details.
