This was interesting. Mostly just visually interesting. Other than a pleasing way to present text, it more mattered what would you do with it. It could just be eye-candy or a purposeful graphic organizer.
My daughter (10) loves to use this when looking at vocab that all links to a subject she is studying. My 6th grade students would probably enjoy this as well!
When I looked at this one I thought it would be fun, but also a great way for my high school students to describe age groups that we're covering in our child development classes or even early childhood theorists.
