Some styles of elementary graphic organizers include Venn diagrams, Know, Want to Know, Learn (KWL) charts and concept maps. Instructors utilize these organizers in a variety of ways and for a variety of subjects.
Venn diagrams allow students to study information for its similarities and differences. KWL charts give students the opportunity to examine their own knowledge base, guiding them towards the things they know and need to know. Concept maps allow students to describe the information they have about an idea.
These graphic organizer styles, and many sub-styles based on them, are available free of charge at teaching resource websites such as Teacher Vision and Theteachertoolkit.com.
