This is a 24 x 36 anchor chart for plate tectonics. It covers convergent, divergent, and transform boundaries. I recommend getting it printed professionally on 55 lb paper because it will make the colors pop really well. I usually get mine printed at Office Depot by uploading the file on their website although I know many schools have large printers which will work just fine.
I use anchor charts to front load vocabulary during the year. Every three weeks my students do a "word wall walk around" where they answer questions about all of my posters in my classroom. Then, when we learn about the content, students are already familiar with the vocabulary and know where the poster is, so they can reference it while practicing the content.
