Cues, Questions, and Advanced Organizers

Hey everyone!  I have been reading a lot about the use of cues, questions, and advanced organizers in ELL classrooms as well as general education classes.  I am very interested in potentially integrating more of these into an elementary setting.  I was wondering if anyone has successfully used them in the lower elementary grades.  I have had some experience using them in 4th-6th, but am finding it especially difficult to see how advanced organizers could be used in K-3.  Any thoughts or suggestions?
