Twenty Eleven Sidebars

I want to create a two column template for my Pages. I’m using Twenty Eleven and I have all my pages’ left columns populated. See https://www.continuumbakersfield.com. But now I want to put three kinds of content down the right column (a sidebar column): a short paragraph; another short paragraph (such as a short quote); and a little highlight box. The content needs to be unique to each page (I’ll have maybe 9 pages total). I cannot figure out how to do this. When I use the Widget function, I get the same content on each of my pages. How can I fix this?
