I'm using a similar method with my content creation... Bubbles inside the big bubble... and at the end, I connect the bubbles... :) (If the topic isn't chronological...)
Thanks for sharing... And yes, it would be great if children would learn more about organizing things and thoughts...
I was actually thinking of doing a post this week or next talking about doing the connections in different styles (e.g. how you might do it for a nonfiction narrative or creative writing context), so you've successfully anticipated my next move 😛
Hehehe... As you have written it down, now you have to do it!
I did some silliness with the blog schedule that pushed the bubbles thing back a week, but I've written something of a follow-up to this and I've got a couple more planned.
