I think the key is to have them practice.
Have you read this thread that discussed individual lists?

This is going to sound offensive to some, and I am soooo sorry!! If I am missing the point, please explain to me (nicely

) what I have missed!
I think a lot of the spelling contracts and centers miss the point. For example-I don't have mine type on the computer a few times b/c I don't want them copying & pasting. I do not have students cut letters out of magazines to spell words. I really want students practicing how to spell the words.
Along with the practice work, we spend time daily reviewing spelling patterns, sorting the words, etc.
