Venn diagrams are used for dealing with two or more interconnecting concepts. The diagrams are illustrated by two or more circles that overlap, with the overlapped area representing commonalities. In language arts, a teacher might use a Venn diagram to help students compare and contrast characters or points in a story, especially prior to beginning a writing project along those lines, according to Think Port. In mathematics, a Venn diagram can show common members of two or more sets.
A teacher might use a W's organizer to help students sort out concepts according to the questions "who, what, when, where and why," suggests Think Port. This can be especially useful in establishing a sequence of events, such as in a social studies lesson or in analyzing the plot of a story in language arts. Teachers might also add the sixth traditional journalism question, "how?"
A cycle diagram is a graphic organizer that illustrates how things that happen as part of a cycle contribute to a predictable result over and over again. In a cycle organizer, events that occur as part of the cycle are represented by boxes arranged in a circle, with each box describing an event in clockwise order according to Write Design Online. A science teacher might use this type of organizer to explain the rain cycle, for example.
A problem/solution outline is a graphic organizer that describes the steps of problem solving, says Write Design Online. The user begins with a problem box in which he answers the questions "who, what, when, where, why and how" about the problem. In a second connecting box, he lists each solution that he has attempted, and the results of each attempt. This could be used in a science class to test hypotheses.
