Summarization Strategies for Elementary Teachers

I am currently in my third year working with a school that was in school improvement. They are now a Missouri school recognized with distinction, but the work continues. My next visit with them will be to help them understand Summarization and Note taking as an instructional strategy as described by Marzano. While I can find lots of ideas for summarization in reading (although mostly at the upper elementary to senior high grades), I am not finding good examples of this strategy at the lower elementary grades. In addition, I would love some specific examples of using summarization in elementary mathematics. If you have any suggestions, I would love to hear from you.
