Basically you the free pdf onto card and it slots together in a sort of honeycomb style. It's a very clever design - completely glue free but very solid. Anyway, I had great fun putting it all together before I passed it on to Joplin! I would imagine that maybe 7 plus years would be able to precisely cut and put this together with a bit of help, but this time I got play!
A great activity I would thoroughly recommend! You can down load it at http://joachimesque.com/globe/
