This word wall occupied one of the walls of my room. I put colored borders around each word depending on the category the word belonged in. (Physical Geography/ Political Geography, Government, Economics, Culture, Environmental Issues). As the year went on and I introduced more vocabulary I would put up the words we were studying and constantly refer to the wall as I was teaching. My students, especially my English Language Learners, loved walking up to the wall, reading through the definition, seeing the Spanish/English translation, and looking at the picture(s).
Some of the words may not fit perfectly into a category or you may find another way you would like to organize the wall depending on the needs of your students. I separated each section on my word wall with a long piece of yarn.
