This is how I set up vocabulary in my world history classroom. There are 5 columns - term, guess, definition, picture, and significance.
As a bellringer, students will complete their "guess" for the vocabulary words that we haven't covered yet. After the lesson, we complete the definition together.
The next day (or for homework) students will draw a picture of the word covered the day before.
After the lesson is finished, students will fill in the "significance" column, which determines why the term is significant in our studies of world history.
I have attached a blank vocabulary graphic organizer, one with terms, and the last is completely filled in.
The file is editable, so you can change it to fit your needs.
Completing vocabulary using this method is extremely helpful and I find that students come away with a better understanding of the terms.
