What do you put on your word wall for upper elementary? Weekly spelling words? Vocab words from the reading unit? Vocab words from social studies/science/other? Words that come up because the kids want to know how to spell them during writer's workshop? Words from a word wall program? I've meant to start a word wall every year in 4th grade, but it never seems to get up and running. I'm not sure how to work it. It seems like either there would be waaaaaaaaaay too many words on it over time (do you switch them around and rotate words off the wall?) and I never know exactly what's supposed to be on there. Your ideas are appreciated. I need to make this happen next year!
