10 things... layout ideas

I'm currently working on the new idea I've had for my "10 things you should know about graphic design" brief. Which is now, not to make a book, but I've been looking at new formats, and I've decided to produce a small concertina booklet.
So I pretty much had the content sorted out, so the next step is to figure our what size and the layout I want to sit in on each page/fold/side of the concertina booklet.
Here are a few designs I've been trying out (the first one I did at the bottom, working it's way to the top with the more recent)
...more to come...



This is the most recent one that I've produced. Big difference between this one and the others is that the number of the 'thing you should know' is fairly large in the top left corner of the page/fold/side with the thin blue line underneath. I haven't yet decided whether I prefer this idea to the one where the number is positioned inside the blue circle....hummm....
but I really like the positioning of the text and the imagery. I think that works really well.



The number in the blue circle....not too sure what I think to this. I like it, but I don't know if it's appropriate. I guess it works with the '10 things..' because I think the numbers definitely need to be there, counting each of the 'things' as you read it. So that's something to think about.
Not sure if I like the positioning of the text and the images as much as I do on some of the other ideas.



The 'thing you should know' in the blue circle.
It's definitely missing the number, that should be included somewhere. It looks good, but I'm not sure how big I'd have to make the circle on some of the pages/sides/folds due to the length of the title, which might look a bit stupid.
Like the image being on the same 'side' as the title then the body of text and the list on the next page.



Like the image being completly on it's own on this one. The all the other information on the next page. Think it works well with the way you might read it. Finding the image more intriguing first that a page full of text. This then making you want to read the text perhaps.



Although this was the first idea I tried, I think it's one of the strongest, the one I think I prefer the most. Just needs a few alterations, such as the number which I now know I need.
Like the layout of the lis, spreading across both pages for each 'thing'.
