The Frayer model is a vocabulary organizer built around one word in a center box and four quadrants around it. The usual four are definition, characteristics, examples and non-examples — and it is the non-examples quadrant that makes it work. Asking a student what is not a mammal, or what is not a polygon, exposes the edge of their understanding far faster than asking for a definition, which they can often produce word-perfect without knowing what it excludes.
Blank Frayer model sheets with a central oval or box for the target word and four labeled quadrants around it. Standard versions use definition, characteristics, examples and non-examples; alternative versions leave the quadrant labels blank so you can set your own headings. All quadrants are ruled and large enough for a short list. Black and white, one per US Letter page.
Most commonly definition, characteristics, examples and non-examples, with the word itself in the center. Variations swap characteristics for essential and non-essential features, or replace one quadrant with a drawing space for younger students. Blank-label versions let you choose.
Why include non-examples?
Because a concept is defined as much by what it excludes as by what it includes. A student who lists square, triangle and pentagon as polygons but cannot say why a circle is not has a fragile definition. The non-examples quadrant surfaces that gap immediately, which is the main reason teachers keep using this format.
Is the Frayer model only for vocabulary?
It started as a vocabulary tool and remains best at that, but it transfers well to any concept with a boundary — a mathematical property, a scientific classification, a genre of writing. Anything where the interesting question is what counts suits it.
What age does it suit?
As an editorial suggestion, roughly age 8 upward, and it stays useful into secondary and adult study. Younger students usually manage best with a drawing quadrant replacing characteristics, since the abstraction of listing features develops later than the ability to give examples.
